If you own an espresso machine and keep wondering why one shot tastes sharp while the next tastes sour, the fastest fix is usually a piece of equipment that costs less than a bag of beans. A bottomless portafilter removes the spout so you can watch the water move through the puck instead of guessing at it from the stream coming out the other end.
We spent weeks running shots through ten different naked portafilters across 54mm, 58mm and 51mm group heads, weighing basket choices and watching how each body seals into the group. What follows is the honest version: which ones actually made our shots more consistent, which ones just look good on the counter, and which machines each one actually fits. We also link to our guides to espresso machines for home baristas and espresso grinders for the bigger picture.
What Is a Bottomless Portafilter?
A bottomless portafilter, also called a naked portafilter, is an espresso machine portafilter with the spout and solid basket floor removed. The coffee puck sits exposed inside a ring, so you can watch the entire extraction as it happens rather than inferring it from the stream that exits below.
With the puck in plain sight you can spot four things a spouted portafilter hides:
- Channeling – one side of the puck draining faster than the other
- Poor distribution – clumps and uneven colour showing before the first drop
- Tamping errors – a tilted or over-tamped puck visible from the side
- Basket defects – blocked holes or a loose basket rim distorting the flow
Do Bottomless Portafilters Actually Make Better Espresso?
No, not by itself. A bottomless portafilter does not change how water moves through coffee. It changes what you can see while it happens, and taste only improves when that visibility makes you correct a mistake you could not previously detect.
The consensus across espresso forums is blunt about this. One thread put it plainly: a bottomless gives you more visual feedback on the quality of your puck prep, and it will not change the taste of your espresso unless you decide to change something. Another thread pushed readers toward the basket as the more meaningful upgrade, arguing that precision baskets from brands like IMS and VST do more for shot quality than the portafilter body does.
That framing matters if you are buying. A bottomless is a diagnostic tool, and its value scales with your ability to read flow. If you have just started pulling shots and cannot yet tell a fast channelled shot from a slow one, a better grinder or a precision basket will pay you back faster.

1. Normcore 54mm Bottomless Portafilter – Best Overall for Breville and Sage Machines
Normcore 54mm Bottomless Portafilter, Naked Portafilter Fits Breville Sage Barista Express Machines, 18g Filter Basket Included, Genuine American Walnut Handle
Stainless steel body
Genuine American walnut handle
18g basket included
320 g
Pros
- Solid all-metal build that feels premium
- Flat rim that lays on the counter for tamping
- Extra clearance under the group for taller cups
- Accepts any Breville single double or triple basket
Cons
- Black finish on some variants wears thin
- Handle shape less ergonomic than the factory Breville one
- Lugs oversized so dosing rings may not lock fully
This is the one we kept reaching for. The Normcore 54mm carries the deepest review history of anything in this roundup at over 2300 ratings, and that volume shows in the details rather than the specification sheet. The rim is flat enough to set the ring on the counter while you tamp, which speeds up puck prep noticeably on a busy workflow.
Fitment is the selling point. It covers the Bambino, Bambino Plus, Barista Pro, Barista Express and Barista Express Impress, and because there is no floor, any basket you already own drops straight in. Swapping in a different basket size changes your dose and flow rate, so expect a short re-dial.
Owners also point out that the low-hanging body gives real cup clearance, which matters if you weigh your shot on a scale with the portafilter still locked in.
The criticisms are worth weighing. The lugs sit slightly large, so third-party dosing rings may not engage fully, and the handle geometry does not match the moulded grip of the factory Breville portafilter. If you upgrade your machine to a 58mm Breville or an E61 group later, this one becomes a paperweight.
Basket Choice and Dose With the Included 18g
The included 18g basket is serviceable, but several owners report it running fast for their roast and grinder combination. A better-machined 54mm basket from a specialist maker changes flow noticeably. If you want to compare grinder setups first, our guide to espresso grinders is worth a read before you re-dial.
Why the Stainless Body Matters Over Months of Use
At 320 g this is a substantial tool rather than a thin shell, and the stainless body with a threaded collar resists the corrosion that creeps into cheaper plated zinc at the group seal. The walnut handle stays cool through a run of back-to-back shots. Wipe it under running water rather than putting the whole ring through a dishwasher cycle.
2. CAPFEI 51mm Bottomless Portafilter – The Practical Choice for 51mm Three-Ear Machines
51mm Bottomless Portafilter 3 Ears Compatible with CASABREWS CM5418 and 3700 Series | with Stainless Steel Double Shot Capacity Cup Filter Basket
51mm three-ear pattern
Ear thickness 3.88-4mm
16g two-cup basket
304 food-grade stainless
Pros
- Only true 51mm three-ear option in this roundup
- Fully detachable for easy cleaning
- Two-cup basket included
- Corrosion-resistant 304 stainless
Cons
- Compatibility wording centres on Mr. Coffee models
- Included basket caps out near 16g
- Minimal published detail on machining tolerances
Thin 51mm machines have the worst aftermarket support of any group size, so finding a real bottomless ring for them is worth a look. This one is a plain, honest piece of stainless engineering. The detachable construction means the basket lifts straight out, which matters on a small machine where a fixed basket is awkward to clean.
The ear thickness spec of 3.88 to 4mm is the detail that decides whether it works on your machine. CASABREWS CM5418 and 3700 series owners generally find the fit correct, and the listing also targets 51mm three-ear groups on other brands.
Where it falls short is dose capacity. The included two-cup basket holds up to 16g, which is fine for most drinks but smaller than the 18 to 20g baskets used on larger machines. You cannot fit a bigger basket inside the ring.
Why 51mm Fitment Is Its Own Category
A 58mm basket will not physically sit inside a 54mm group, let alone a 51mm one, and this is the single most common return in the category. Measure the inside diameter of your group basket seat before ordering anything on this list. A cheap caliper or a printed template takes under a minute and saves the return.
Cleaning and Build on a Small Machine
The 304 stainless body handles constant rinsing without staining, and the fully detachable layout means no hidden corners to trap grounds. Machining tolerance detail is not published, so test the lock-in with a dry basket and empty group first.
3. CREMA 58mm Bottomless Portafilter – Best Value for Breville 58mm Groups
CREMA Coffee Products 58mm Bottomless Naked Portafilter | Compatible with 58mm Breville Machines | Includes Double Shot Filter Basket | Walnut
Breville 58mm lug pattern
Machined stainless body
Solid walnut handle
Non-pressurized double basket
Pros
- Weighty feel with a long handle for leverage
- Bare basket design speeds up puck resets
- Walnut handle is comfortable and handsome
- One of the few clean fits for Breville 58mm
Cons
- Handle can loosen during use
- Junction feels cheap after long service
- Included basket not interchangeable with factory Breville baskets
The long handle does more work than it looks. On a 58mm Breville lug pattern, the extra length gives you real control when you twist the ring to seat it, and the weighted body removes the rattle you get with thin rings. The polished interior means the basket drops in cleanly instead of catching on the collar.
Read the fit note carefully before buying. This is built to the Breville 58mm pattern used on the Dual Boiler, Oracle and Oracle Touch, and it is explicitly not interchangeable with E61 group heads. That distinction catches a lot of buyers who assume all 58mm rings are interchangeable.
Owners with a Breville 58mm machine often report it is the only bottomless ring that seated cleanly on their unit, which is worth more than an extra accessory in the box.
Why the Handle Loosens and What to Do About It
Several owners report the handle wanting to back off and the junction feeling loose after extended use. A quarter turn by hand before each session, and periodic tightening with the correct driver, keeps it solid. It is a serviceable annoyance rather than a defect.
Basket Compatibility on 58mm Breville
The included non-pressurized double basket is a sensible starting point, but it does not swap with the factory Breville basket. Bring your existing 58mm basket with you rather than assuming it fits.
4. Teyearlife 54mm Bottomless Portafilter – Best Budget Route Into a 54mm Bottomless Set-Up
Teyearlife 54mm Bottomless Portafilter for Breville Barista Express Pro Touch Bambino Infuser Espresso Accessorie produced with original porta filter as mold Not damage BES500’s brewing head
Fits Breville 8-series models
5mm lug thickness
18-20g basket
53.3mm puck screen
Pros
- Cheapest way to try a bottomless on a 54mm Breville
- Thin 5mm lugs avoid marking the group
- Basket and puck screen both included
- Clear visibility of channeling
Cons
- Handle texture can vary between batches
- Long-term durability not well documented
- One-star share runs higher than premium rivals
The thing that separates this from other budget rings is the puck screen in the box. Most entry listings give you a bare ring and a basic basket, and then you spend the difference on a screen anyway. Here the 18 to 20g basket and a 53.3mm screen both come in the kit, and the screen does more for early puck stability than most people expect.
Fitment covers the common 54mm Breville models including the 880BSS, 878BSS, 870XL, 840XL and 500BSS. The cast stainless head is moulded from the factory portafilter profile, which is the reason it seats without a fight.
The 5mm lug thickness is a deliberate choice over the 5.5 to 6mm alternatives, and it reduces the risk of marking the group head collar on a machine where the brewing head is easier to damage.
What the Puck Screen Actually Fixes
A puck screen is not a channeling cure, but it holds the top of the bed together while the basket fills and it reduces the amount of loose coffee that lifts and sprays. On a 54mm machine with tight cup clearance it also cuts the number of grounds that end up in the drip tray. Paired with WDT and a level tamp, it makes the first weeks far less messy.
Where the Budget Tier Shows
Handle texture varies a little between batches and the long-term durability record is thin, with a higher share of one-star ratings than the premium 54mm options. If you want a ring that looks as good on the counter as it performs, pay up. If you want to see flow tomorrow for the least outlay, this works.
5. YMWVH 58mm Two-Ear Bottomless Portafilter – The Rare Pick for Gaggia Two-Ear Groups
YMWVH 58mm Bottomless Portafilter 2 Ears for Gaggia Espresso Machines
58mm two-ear pattern
Food-grade stainless head
Natural rosewood handle
18g basket included
Pros
- Fills a fitment gap most listings ignore
- Mirror-polished head and rosewood handle
- 18g basket in the box
- Listing includes real troubleshooting guidance
Cons
- Long exclusion list of Gaggia models
- Splashing common before the grind is dialed
- Wood handle must be hand-washed
- Highest one-star share here
Most 58mm bottomless rings sold online are built for E61 groups, which is not what a Gaggia Classic uses. This one is cut for the two-ear 58mm pattern, and that specificity is the entire reason to consider it.
It covers the Baby, Classic, Espresso Deluxe, Evolution, New Baby, New Baby 06, New Espresso 06 and Tebe. It explicitly excludes the Carezza, Cubika Plus and Gran Gaggia Prestige and Deluxe, and it does not fit Breville Dual-Boiler or Oracle machines.
The head is hand-polished stainless steel with a natural rosewood handle, and an 18g stainless basket comes in the box. The listing even explains why uneven dose and distribution cause spray and why you should tamp after distributing.
Gaggia Generations Are Not All the Same
Owners on Gaggia forums repeatedly point out that pre-2015 Classic, Classic Pro and Evo Pro units are all called 58mm but do not share identical group dimensions. Measure the basket seat diameter on your specific machine before ordering, and expect a tight fit that takes some force. Several owners accept this once they know it is normal.
The Rosewood Handle and Hand-Wash Routine
Rosewood looks the part and stays cool during a long session, but it rules out the dishwasher entirely. Pull the basket out, rinse the ring under running water, and dry the handle promptly. That is a few extra minutes of work in exchange for a grip that does not slip when wet.
6. KNODOS 54mm Bottomless Portafilter – Best for Third-Party Basket Flexibility
KNODOS 54mm Bottomless Portafilter Breville Compatible, Rosewood Handle
54mm Breville and Sage fitment
18-21g capacity basket
Accepts IMS and VST baskets
Rosewood handle
Pros
- Snug leak-free fit on listed Breville models
- Wide basket compatibility including IMS and VST
- Well balanced rosewood handle for tamping
- Larger 18-21g basket than the 18g standard
Cons
- Only three handle finishes offered
- Limited detailed customer write-ups available
The reason to like this ring is the basket. It accepts third-party 54mm baskets from IMS and VST directly, and the included one runs 18 to 21g rather than the standard 18g. On a 54mm Breville that extra capacity lets you push a slightly larger dose without a different basket, which changes the flow profile and the shot profile with it.
It covers a wide slice of the Breville and Sage line-up including the Barista Express, Barista Pro, Barista Touch, Bambino, Bambino Plus, Infuser and Duo Temp Pro. Owners report a snug seal with no weeping at the ears, and the rosewood handle stays comfortable over a multi-shot session.
Why Basket Precision Outranks the Portafilter Body
Owners repeatedly tell us to spend the money on the basket if shot quality is the goal, and precision baskets from IMS and VST carry the strongest reputations in that category. A better-machined basket with tighter hole tolerance controls flow rate more directly than the metal ring around it. This is the ring that lets you act on that advice without hunting for a matching basket.
Swapping Baskets Means Re-Dialing
Moving from an 18g basket to a 21g basket, or to a higher-extraction IMS or VST pattern, changes dose and resistance. Expect to grind finer and re-check yield before blaming the portafilter. Weigh every shot during this period rather than trusting the cup.
7. CASABREWS 58mm Three-Ear Bottomless Portafilter – Best Match for Casabrew Ultra and 5700 Owners
CASABREWS 58mm Bottomless Portafilter with 3 Ears for Ultra and 5700 Series
58mm three-ear pattern
Ear thickness 5.9mm
Basket and puck screen included
Solid wood handle
Pros
- Same-maker tolerances as the machine itself
- Better machined basket than the factory one
- Reduced hang height fits a taller cup on a scale
- Sealed wood handle resists staining
Cons
- Very tight initial fit needs real force
- Included puck screen is undersized
- Basket spring stiff for the first dozen shots
Buying a spare from the same manufacturer as your machine removes the tolerance guesswork that dominates forum threads about this category. It fits the 5700Gense, 5700Pro, CM5700, Neutron Pro, Ultra and 4700Gense. It does not fit the 3700Gense, which is a 51mm group.
The basket is the quiet upgrade here. Owners note a machined groove in place of a printed maximum line, which is a small detail that signals better machining than the original part. The lower hanging height also lets a taller cup sit on a scale, which our guide to home espresso machines under 500 dollars covers in more depth.
Managing the Tight Fit
This ring seats tighter than the factory portafilter and can take real force on first installation. Push it on with the handle and check that both ears are fully engaged before pulling the lever. Once in place it loosens marginally with use and settles into a reliable seal.
Buy a Better Puck Screen Separately
The included screen is consistently reported as undersized, letting fines creep through. Measure the screen diameter yourself and pick a matched puck screen from a specialist maker. It is a small cost against how much it reduces spray and keeps the group cleaner.
8. IKAPE 58mm Bottomless Naked Portafilter – Best Open Sightlines for E61 Machines
IKAPE 58mm Bottomless Naked Portafilter, Black Compatible with E61,Rocket,Sanremo,Slayer,Flair 58,ECM,etc.Espresso Machines(20g Basket Included)
58mm two-ear E61 pattern
20g stainless precision basket
Open-work head with arc cut-outs
Detachable handle and basket
Pros
- Seals cleanly with no weeping on E61 groups
- Arc cut-outs give excellent sightlines
- Solid wood-to-metal joint stays dry
- Accepts standard 58mm baskets
Cons
- Included basket has a fine mesh layer that is hard to clean
- Unpolished hexagonal hole edges
- Untapered basket increases flow rate and spray
The open-work head is the detail that sets this apart. Rounded arc cut-outs in the ring wall give you a wider sightline to the puck than a solid wall, so you can watch the bed from the side without tilting the machine forward.
It fits the 58mm two-ear E61 pattern used by E61 groups, Rocket, Sanremo, Slayer, Flair 58 and ECM machines. Owners running Slayer and Lelit Victoria units report a clean seal with no leaking at the ears. The wood-to-metal join stays dry through repeated rinsing, and both handle and basket detach.
Replace the Included Basket for Cleaner Results
The high-extraction basket that comes in the box has a fine mesh layer that traps fines, can pop loose during washing and leaves unpolished edges on the hexagonal holes. Several owners swap it for a standard 58mm basket. That single change removes most of the splashing people attribute to the portafilter itself.
E61 Interchangeability and Its One Exception
Forum threads on Lelit Elizabeth and ECM machines make the general rule simple: any E61 portafilter fits any E61 group. The exception is older VBM units, whose lugs were thinned at the factory and will not accept a standard ring. Check the ear thickness on an older commercial machine before ordering.
9. Rocket Espresso 58mm Bottomless Portafilter – Best Full 90-Degree Lock-In for Rocket Owners
Rocket Espresso 58mm Bottomless Portafilter
58mm E61 and Rocket fitment
21g basket included
Made in Italy
Heavier body than factory
Pros
- Turns fully through 90 degrees in E61 groups
- Heavier and more precise than the factory ring
- Deep body clears taller cups
- Rated highly by Rocket and Profitec owners
Cons
- 21g basket is proprietary and not interchangeable
- Larger basket diameter makes the bed shallower
- One owner found the basket sizing unsuited to their machine
This is the factory answer for anyone who wants a Rocket ring that actually behaves like a Rocket part. Owners running Rocket, Profitec, Quickmill and Brazilia machines give it the strongest rating profile of anything we tested here, and the reason keeps coming back to lock-in.
Generic E61 rings can stop part way and never fully seat. This one turns all the way through 90 degrees, which removes that partial-fit risk and the channeling that follows from it.
It is also made in Italy, and the extra weight compared with the factory ring gives it a more precise feel when you twist it into the group.
The Proprietary 21g Basket Trade-Off
The included 21g basket does not swap with the one from the factory portafilter, and its larger diameter spreads the bed shallower and wider than you are used to. That changes extraction even though the ring is identical. Dial in by weight from scratch rather than copying your old settings, and expect a slightly drier, less heavy shot.
Clearing a Taller Cup Under the Group
The deeper body gives more vertical clearance than the factory part, which matters when weighing shots or working with a larger cup on a low counter.
10. Normcore 58mm Slim Bottomless Portafilter – Best Slim Profile for Counter Clearance
Normcore 58 mm Silm Naked Bottomless Portafilter Fits E61 Group Head, ECM, Rocket, Sanremo, Synesso, Slayer, VBM, Black Anodized Aluminum Handle and 18g Basket
58mm E61 group fitment
Slim flat-laying body
Manually lathed anodized handle
18g basket included
Pros
- Slim profile gives real cup and scale clearance
- Flat rim makes tamping on the counter easy
- Smooth anodized handle stays comfortable
- Widely reported to reduce or stop channeling
Cons
- Lug tabs do not match the ECM wedge shape
- Handle twists loose and needs tightening
- Included high-extraction basket yields little crema
- Will not fit Ascaso Decent or Flair 58
The slim body is the whole point. It hangs lower and less than most 58mm rings, so a cup sits on a scale underneath it without you tilting the machine, and the flat rim lets you set it down for tamping instead of balancing it on a knock box.
It fits 58mm E61 group heads, ECM, Rocket, Sanremo, Synesso, Slayer and VBM. It explicitly does not fit Ascaso, Decent or Flair 58 machines, so check your group before ordering.
The ECM Lug Tab Mismatch Explained
The rectangular lug tabs on this ring do not match the tapered wedge tabs used by ECM. On an ECM group it may not lock fully, and a partial lock is exactly what produces channeling. If your machine is an ECM, choose a ring built for the ECM tab shape rather than forcing this one.
Choosing a Basket That Suits Milk Drinks
The included high-extraction basket wants a much finer grind and produces a thin, translucent crema that suits straight espresso but disappoints in a latte. For milk drinks, fit a standard 18g basket instead and re-dial. Basket choice matters more here than the ring itself.
How to Choose a Bottomless Portafilter That Actually Fits
Measure Your Group Before Anything Else
Port size is the only dealbreaker in this category. A 58mm basket will not drop into a 54mm group, and it will not sit properly in a 51mm group either. Check the diameter stamped into your factory basket or measure the seat directly, then match it to the listing before you order anything.
- 54mm – Breville Barista Express, Barista Pro, Barista Touch, Bambino, Bambino Plus, Infuser, Duo Temp Pro, Sage models
- 58mm E61 two-ear – Rocket, ECM, Profitec, Lelit Victoria and Bianca, Sanremo, Slayer, Flair 58
- 58mm Gaggia two-ear – Gaggia Classic, Baby, Evolution, Espresso Deluxe
- 58mm three-ear – CASABREWS Ultra, 5700 series, Neutron Pro
- 51mm three-ear – DeLonghi Dedica, CASABREWS 3700 series, Mr. Coffee machines
Machine generations inside a single product line matter too. Gaggia Classic, Classic Pro and Evo Pro units are all sold as 58mm and do not share identical dimensions, so measure your specific unit rather than the product line.
Straight Handle or Angled Handle?
This is the question that never gets answered in other roundups. Angled handles, the pattern associated with ECM-style designs, drop the grip below the group head as you lock in. That helps with tall cups and gives the wrist a natural angle on prosumer machines. Straight handles stay horizontal, which some owners prefer for tamping leverage and scale clearance. Neither changes the cup.
Body Material Decides How Long It Lasts
Stainless steel bodies survive years of daily rinsing and group-seal wear. Zinc alloy bodies feel fine on day one and can pit at the collar over time. Beyond material, weight tells you more than the listing copy does. A ring that feels thin and light usually has thin ears, and thin ears are where leaks start.
Basket Precision Is Where the Money Goes
A stamped basket with punched holes gives uneven flow compared with a precision-machined basket with tighter tolerances. If your ring accepts third-party baskets, you can upgrade later instead of being stuck with what was in the box. That matters because the included basket is often the weakest part of an otherwise good ring.
Adding the Rest of the Kit
A WDT tool and a puck screen do more for early consistency than any portafilter upgrade. If you are still choosing a machine, our espresso machine picks for small kitchens guide is useful for compact setups where clearance is the deciding factor.
Downsides and When to Skip a Bottomless Portafilter
The honest answer is that bottomless brewing is messier for the first few weeks. Here is what you are signing up for:
- Splash and spatter, especially before the grind, distribution and tamp are dialed in
- A learning curve of roughly one to two weeks where you read flow instead of just drinking
- No spout to split the stream, so double shots must be jugged from a single flow
- Hand-washing for any ring with a wooden handle
- Zero tolerance on fitment, since the wrong port size means it never locks in at all
If you pull shots without weighing, cannot tell a channelled shot from a slow one, or have a machine where clearance under the group is already tight, a precision basket will serve you better. Many owners who reverted to a spouted ring during the messy phase came back once their dial-in was solid.
Frequently Asked Questions
Do bottomless portafilters make better espresso?
Not on their own. Removing the spout lets you see channeling, uneven distribution and tamping errors in real time. Flavor changes only when that visibility makes you correct a puck-prep or grind mistake you could not previously detect. Baristas who are already dialing in by weight get the most value; beginners who cannot read flow yet should upgrade the grinder or the basket first.
What are the disadvantages of using a bottomless portafilter?
Five things to expect: splash and spatter during the first weeks, a one to two week learning curve, no spout to split the stream so double shots must be jugged from one flow, hand-washing if the handle is wooden, and the need to get the port size exactly right or it will not fit at all. Once the grind and tamp are dialled in, the mess largely stops.
Does a bottomless portafilter make more crema?
Not directly. Crema is driven by dose, grind fineness, roast freshness, temperature and basket precision. What a bottomless does is reveal uneven flow so you can fix it, which can improve perceived crema quality. Some high-extraction precision baskets shift the result toward a thinner, more translucent crema that some drinkers read as less crema overall.
Is there a difference between bottomless portafilters?
Yes. The differences that matter are port size, body material and weight, basket precision, handle profile, and whether the ring is straight or angled. Cosmetic details like the wood species of the handle do not change the cup. Port size is the only one that decides whether the ring fits at all.
Why is my bottomless portafilter spurting and splashing?
Work through this order. First, grind finer and check yield in grams rather than by time. Second, distribute with a WDT tool after dosing and before tamping. Third, level the bed in the basket so the coffee sits flat before you tamp. Fourth, tamp once, level, with no twist. If it still spurts, look at the grinder distribution and the dose weight against your basket capacity.
Which Bottomless Portafilter Should You Buy in 2026?
If you run a Breville or Sage 54mm machine and want the most proven option, the Normcore 54mm Bottomless Portafilter is our top pick. It has the deepest review history here, comes with an 18g basket, and accepts any basket you already own.
If you own a Breville 58mm group, the CREMA 58mm offers the best balance of weight, handle length and price. For Rocket, Profitec and other E61 machines, the Rocket Espresso 58mm gives you a full 90-degree lock-in that generic rings cannot match, while the IKAPE 58mm is the pick when you want the widest sightline to the puck.
Gaggia Classic owners should look at the YMWVH 58mm Two-Ear after measuring their specific machine. Casabrew Ultra and 5700 owners will find the maker-matched CASABREWS 58mm Three-Ear the least frustrating install. If you are on a 51mm machine, the CAPFEI 51mm is realistically your only route in.
Whichever you choose, measure the group first and pair it with a WDT tool and a puck screen. Our roundup of home espresso machines covers the machines these rings fit, and the full ten-product table above sits right after our top three if you want to compare everything side by side before you commit.
