Best Espresso Accessories

Making espresso at home involves several small steps before and after the shot, and the right accessories make those steps cleaner and easier to repeat.

A knock box gives spent pucks somewhere to go, a pitcher holds milk for steaming and pouring, a scale tracks your dose and shot time, and a puck prep kit helps you build an even coffee bed before you lock in the portafilter.

The catch is fit: tamper kits are sized for specific portafilters, so the size on the listing matters more than the number of pieces in the box.

To find the best espresso accessories for a home coffee bar, we compared listing specifications and product descriptions with Amazon owner reviews where they were available.

The group covers knock boxes from Breville and MHW-3BOMBER, an Adorever milk pitcher, scales from Fellow and TIMEMORE, puck prep kits from Reoszeank, JOEZEST, troletoi, and Y-Step, and Fellow’s Monty espresso cups.

How to Choose the Best Espresso Accessories

Knock Boxes for Spent Pucks

After each shot, the used coffee stays in the basket as a compact puck.

A knock box catches it: you strike the portafilter against the knock bar and the puck drops into the bin, which keeps wet grounds out of the sink.

The Breville BEA501BSS Knock Box 10 holds up to 10 pucks, pairs brushed stainless steel with plastic, and has a removable knock bar so the inner vessel is easy to clean.

Breville says the compact body can be stored on the drip tray when not in use, and it is designed to complement the Breville range of espresso machines.

The MHW-3BOMBER GB5967B has the larger bin of the two: a square 1.2L design that MHW-3BOMBER rates for up to 15 pucks.

Its ABS body has a slanted mouth meant to keep residue inside, a metal knock bar with a rubber sleeve to reduce noise, and a silicone non-slip pad on the bottom to protect the counter.

MHW-3BOMBER says it rinses clean with water without disassembly. For more options, see our picks for the best espresso knock boxes.

Milk Pitchers for Steaming and Latte Art

If your machine has a steam wand, a stainless steel pitcher is where you steam the milk, and its spout controls the pour into the shot.

The Adorever Milk Frothing Pitcher is chrome-finished stainless steel with a pointed spout that Adorever says helps prevent leaks and shape the pattern, and it comes with a latte art pen for drawing details in the foam.

This listing is the 12oz size, and the title lists the same pitcher in sizes from 8.5oz up to 66oz. Adorever says it is dishwasher safe and describes the joint between the handle and body as firmly welded.

The Y-Step kit also includes a small milk pitcher, which Y-Step says has measurement markings inside and outside. Our guide to the best milk frothing pitchers covers more shapes and sizes.

Scales for Dose and Shot Time

A scale lets you weigh the ground coffee going into the basket and the espresso coming out, and a built-in timer tracks how long the shot runs. Both scales here are listed as espresso scales with a timer.

The Fellow Tally Pro Coffee Scale with Timer has an OLED display, a metal dial, a removable weigh pan, a glass top, and USB-C charging, plus a Brew Assist mode that lets you set a ratio and follow an on-screen target.

Some owners describe its readings as nearly instant. One owner, who brews other methods, noted that its size may make it a poor fit as an espresso scale, so check its footprint against your drip tray before you buy.

The TIMEMORE Basic 2.0 is a compact, low-profile scale with a backlit LCD, an automatic timer, a water flow rate function, a tare button, and a reset button on the bottom.

It is built from acrylic with a waterproof dial surface, a closable charging port, and an included silicone pad, and TIMEMORE says it shuts off automatically after a short standby period.

Our list of the best coffee scales includes more models.

Tampers, Distribution Tools, and Puck Prep Kits

Puck prep tools work in sequence. A dosing funnel sits on the portafilter so grounds stay in the basket while you dose and stir.

A WDT tool uses thin needles to break up clumps, a distributor levels the bed, and the tamper compresses the grounds into an even puck.

A puck screen then goes on top of the tamped coffee: troletoi and Y-Step say theirs spread water evenly over the grounds and help keep the brew head clean, and JOEZEST says its screen helps reduce channeling.

The four kits differ in what they include. The Reoszeank 51mm kit has a dual-head tool with a distributor on one side and a tamper on the other, a WDT tool, and a magnetic dosing funnel.

Some owners describe its metal pieces as heavy and sturdy, and some say the funnel cuts down on mess.

The JOEZEST 51mm kit pairs a stainless steel tamper with an ergonomic handle with a WDT tool, a magnetic dosing funnel, and a reusable puck screen.

If you want a spring-loaded tamper, look at troletoi and Y-Step.

The troletoi 7 PCS kit has a 53.3mm spring-loaded tamper whose force adjusts by rotating the handle, an adjustable distributor, a WDT tool, a dosing funnel, a reusable puck screen, a tamper mat, and a silicone air blower for clearing loose grounds.

The Y-Step 25 PCS kit has a calibrated spring-loaded tamper with a ripple base and a visual scale for pressure, a magnetic dosing funnel, a puck screen, a WDT tool, and a tamper mat, plus latte art extras: a milk pitcher, stencils, a latte art pen, a stirring spoon, and a towel.

Several Y-Step owners like having everything in one set, but one owner reports that the tamper’s threads wore out after a few months.

Matching Portafilter Size to Your Machine

A tamper kit only works if it matches your portafilter. The Reoszeank, JOEZEST, and Y-Step kits are all 51mm. Reoszeank lists DeLonghi, CASABREWS, and atatix machines with 51mm portafilters, and Y-Step asks buyers to measure the portafilter diameter before ordering.

The troletoi kit is built for Breville 54mm espresso machines and portafilters and uses a 53.3mm tamper.

Check your machine’s manual or measure the basket before you order, since a tamper or funnel in the wrong size will not sit properly in the portafilter.

The knock boxes, scales, pitcher, and cups in this list are not tied to a portafilter size in their listings.

Espresso Cups

Espresso is served in small cups, and the inside shape affects how a milk pour settles on top.

The Fellow Monty Milk Art Espresso Cups come as a set of 2 double-wall ceramic demitasse cups with a 3 oz capacity, a matte black finish, and a graphite base.

Fellow says the curve of the interior base is designed for latte art, lifting the crema as you pour, and the cups stack for storage. Fellow also says not to microwave them.

The feature list calls them dishwasher safe, while a specification line says hand wash only, so check the packaging before you put them in the dishwasher.

Who Should Look Elsewhere

If you only need a tamper and already own the other tools, a full kit adds pieces you may not use; our guide to the best espresso tampers focuses on tampers alone.

If your portafilter is not 51mm or 54mm, none of the kits in this list will fit, so look for a kit sized for your machine.

If your espresso machine has no steam wand, a pitcher on its own will not froth milk, and our picks for the best milk frothers are a better starting point.

Anyone who wants cups that can go in the microwave should skip the Fellow Monty, since Fellow says not to microwave it.

Frequently Asked Questions

Which espresso accessories should I buy first?

Start with what your setup is missing. A tamper that fits your portafilter and a scale with a timer cover the core steps of pulling a shot, and a knock box keeps cleanup tidy.

Add a milk pitcher if your machine has a steam wand, and cups once the rest of the routine is in place.

How do I know which tamper kit fits my machine?

Check the portafilter size in your machine’s manual or measure the basket. In this list, the Reoszeank, JOEZEST, and Y-Step kits are 51mm, and the troletoi kit is for Breville 54mm portafilters. Y-Step specifically asks buyers to measure the portafilter diameter before ordering.

Why is the troletoi tamper 53.3mm if the kit fits 54mm portafilters?

The tamper diameter and the portafilter size are listed separately. troletoi sells this kit for Breville 54mm espresso machines and portafilters with a 53.3mm tamper, so go by the stated machine compatibility rather than the tamper number alone.

What does a puck screen do?

A puck screen sits on top of the tamped coffee in the basket. troletoi and Y-Step say their screens spread water evenly over the grounds and help keep the brew head clean, and JOEZEST says its screen helps reduce channeling.

All three describe their screens as reusable.

Are the Fellow Monty cups dishwasher safe?

The listing is not consistent. Its feature list says Monty is dishwasher safe and does not need hand washing, while a specification line says hand wash only. Fellow is clear that the cups should not go in the microwave.
