New espresso machine owners face a wall of accessories: scales, funnels, distributors, WDT tools, puck screens, bottomless portafilters, knock boxes, and a dozen gadgets that promise café-quality shots. The truth is more reassuring. You need surprisingly little to make excellent espresso, and the first accessories worth buying are the ones that remove a variable you cannot see or control — not the ones that look the most impressive on the counter.
This guide organizes the buying decision into three tiers: what genuinely changes your shots, what improves your workflow once you are consistent, and what can wait until you hit a specific limit. If you already own a machine with a built-in grinder and built-in scales, skip the duplicate purchases and start at tier two.
The honest starting point
Before you buy anything, take stock of what your machine already gives you. A modern espresso machine with a built-in grinder removes the two biggest first purchases: a grinder and, in machines with integrated scales, a way to weigh dose and yield. The what-comes-in-the-box guide lists the accessories that ship with the Meraki, and the full accessories guide gives you the complete landscape if you want to browse everything at once.
The principle that decides every purchase below is simple: espresso fails when a variable changes between shots. A scale removes guessing, a consistent tamp removes uneven pressure, and a distribution tool removes clumps. Buy in that order — measurement first, then consistency, then convenience.
Tier one: the things that change every shot
An accurate scale. If your machine does not have built-in scales, a 0.1 g scale is the single highest-value accessory you can own. Espresso recipes are defined by the weight of ground coffee in and liquid coffee out; a difference of a gram changes the strength and flavor noticeably. You do not need a connected, app-driven scale — you need one that fits under your cup, reads in 0.1 g steps, and has a timer. If your machine weighs dose and yield for you, this purchase disappears entirely.
A tamper that fits your basket. If the tamper that came with your machine sits flat and matches the basket diameter, use it and spend your money elsewhere. What matters is not the handle material or the brand — it is that the tamper fits without rocking and that you can apply even pressure. A poorly fitting tamper leaves one side of the puck denser than the other, and no other accessory fixes that. The Meraki tamper page shows the fit and finish to look for when you do upgrade.
Tier two: consistency once the basics are stable
Once your dose and tamp are consistent, the next source of shot-to-shot variation is distribution: how evenly the grounds sit in the basket before you tamp. Two inexpensive tools solve the most common version of that problem.
A dosing funnel keeps coffee in the basket while you grind or transfer grounds, which sounds minor until you have swept coffee off the counter for the tenth time. More importantly, it lets you level the bed without knocking grounds off the rim, which improves how evenly the puck compresses. If you single-dose into a portafilter, a funnel is the first workflow upgrade worth buying.
A WDT tool uses a few thin needles to stir the grounds in the basket before you tamp. Grinders produce clumps, and clumps create channels that let water race through part of the puck; the result is a shot that is sour and bitter at the same time. Thirty seconds of stirring with a WDT tool is the most reliable way to reduce channeling without changing anything else. The dosing-funnel article explains why the funnel and WDT pair so well, and the puck-screens guide covers a related accessory that some people add at this stage.
The basket: your machine’s real interface
One accessory category deserves special attention because beginners skip it: baskets. The basket is where dose, grind, and water meet, and its size sets the range of shots you can pull. A standard 58 mm basket holds the industry-standard dose range, which is why the Meraki uses that format and why its 58 mm basket is worth checking if you are replacing a worn one. If you mostly make single doses, a 12 g basket can make those shots easier than under-dosing a larger basket — the espresso basket guide explains the relationship in detail.
The reason baskets belong in the “buy first” conversation is that they interact with every other accessory. A dosing funnel and WDT tool are sized to the basket, a tamper must match its diameter, and a precision basket changes how much headroom your dose needs. Buy the basket first, then buy the tools that fit it — not the other way around.
Tier three: workflow and cleaning
When your shots are consistent, the accessories that matter next are the ones that make the routine faster and cleaner. A knock box gives you a padded bar and a container for spent pucks, so you stop tapping the basket on the edge of the trash bin. A barista cleaning brush makes the post-shot group-head wipe a two-second habit, and a blind basket is needed for the backflush cycle that many manuals prescribe. The knock-box guide and the cleaning-tools guide cover what to look for in each.
For machines whose manuals recommend backflushing, the blind basket is not optional shopping — it is a maintenance requirement. If your machine came without one and the manual describes a backflush, buy the manufacturer’s basket rather than a random third-party one; the fit matters because the seal is the point.
What can wait
Several popular accessories only earn their place after you can pull a clean shot with basic gear. A bottomless portafilter is a diagnostic tool as much as a visual upgrade — it shows you channeling in real time, but only useful if you already know what to look for. A bean hopper or single-dose workflow matters when you start switching beans often. Precision baskets, puck screens, and dosing cups all refine variables that beginners usually cannot isolate yet. The accessories-you-can-skip guide goes through this list in detail and names the items that rarely earn their counter space.
A useful habit is to give every potential purchase a one-line job description before you order it. If you cannot write “this tool fixes X, and X happened to me this week,” the accessory is a decoration, not an upgrade. When you can name the specific failure — grounds on the counter, channeling in the puck, or a shot that runs fast — the tool that fixes it will be obvious, and it will probably be one of the items on this list.
A sample first-order list
| Stage | Buy first | Why |
|---|---|---|
| Day one | 0.1 g scale (if no built-in scales); check your tamper fits | You cannot dial in what you cannot measure |
| First month | Dosing funnel; WDT tool | Even distribution removes the most common beginner inconsistency |
| When routine feels stable | Knock box; cleaning brush; blind basket | Faster workflow and proper maintenance |
| Later, on purpose | Bottomless portafilter; puck screen; precision basket | Each solves a limit you can name |
Buying in this order also protects your budget: most tier-two and tier-three items are small, and the mistakes you make early — buying the wrong basket size, or an accessory for a machine you replace — happen less when you buy fewer things.
The bottom line
Your first espresso accessories should do three jobs in order: weigh the coffee, distribute it evenly, and keep the routine clean. A scale (if you need one), a fitting tamper, a dosing funnel, and a WDT tool cover almost all of the measurable improvement available to a beginner. Everything else — bottomless portafilters, puck screens, and the rest — can wait until you can say exactly which problem it solves. Start with the machine you already own, add the tools that remove variables, and let your shots tell you when it is time for the next purchase.
