🔧 Espresso Machines · 2026Every espresso accessory we have verified against a live listing, in one place: bottomless and spouted portafilters by size, WDT tools, and the honest take on what a new machine owner actually needs first.

This page is our accessories catalog in the open: every espresso accessory below was verified against its live listing - fitment claims are the listings' own words, sizes match machines we actually chart, and nothing is here because a marketplace algorithm liked it. The honest priority order for a new machine owner: a scale first (unglamorous, transformative), a WDT tool once you chase consistency, and a bottomless portafilter when you want the machine to tell you the truth about your prep.
Zeroth: a gram scale - not carded below because any accurate $15 kitchen scale works, and it improves shots more than everything else here combined; the manufacturer recipes on our how-to-use guide are unusable without one. First: a WDT tool, the needle distributor that breaks up grinds clumps before tamping - our WDT guide covers the 2005 origin and technique. Second: a bottomless portafilter in your machine's size, which turns every prep flaw into visible spray and channeling - the cheapest diagnostic in espresso. Spouted spares and brushes follow as ownership items, not upgrades.
Every portafilter accessory is size-specific, and the number is your machine's group diameter: 54 mm across most home Brevilles, 58 mm on the commercial standard (Gaggia, Rancilio, Lelit, La Marzocco), 51 mm on several compact De'Longhis. Our portafilter size chart documents every machine we cover with sources - check it before buying anything below, because the fitment lines on the cards are the listings' claims for specific machines, quoted as such.
Distribution levelers that spin a flat blade over the puck surface (they decorate the top millimetre; WDT works the full bed), knock boxes and tamping mats as accessories-of-urgency (buy them when the counter tells you to), and the infinite shelf of dosing rings, funnels and stirrers that arrive free with other tools - our WDT picks include the funnel case where the listing bundles one. The absence of a category below usually means we have not verified a listing worth trusting, not that the category is worthless - the milk frother and Flow Control cap pages carry their own verified gear.
The complete verified accessories catalog - eight items, every fitment line paraphrasing the listing's own statement, sizes matched to the machines we chart.

Check price on Amazon →In honest priority order: a gram scale (any accurate one), a WDT distribution tool, and a bottomless portafilter in your machine's size. Everything else - spare spouted portafilters, brushes, mats - is ownership convenience rather than shot improvement.
Match your group size: 54 mm for most home Brevilles, 58 mm for the commercial-standard machines (Gaggia, Rancilio, Lelit, La Marzocco), 51 mm for several compact De'Longhis. Our portafilter size chart documents every machine we cover, with sources.
As a diagnostic, absolutely - it makes channeling and uneven prep visible as spray and dead spots, which is information a spouted portafilter hides. As a daily driver it is a preference. Every bottomless option below states its machine fitment from its own listing.
The technique is the most broadly adopted prep step in modern espresso: needle-stirring the dosed grounds breaks clumps and evens density before tamping, and its effect shows immediately through a bottomless portafilter. Our WDT guide covers technique and the verified tools.
Because your machine almost certainly shipped with a workable one, and premium tampers are among the most marketed, least shot-relevant upgrades in espresso. Spend that money on a scale and a WDT tool first; revisit tampers only if yours is genuinely poor-fitting.
