Cuisinart CBM-20 Review

What it is and who it's for

The Cuisinart CBM-20 is a 40mm conical-burr electric grinder in the sub-$100 bracket, marketed almost entirely at the household filter-coffee drinker. The spec sheet tells the story: stepped adjustment across 18 settings, a fixed 450 rpm motor, a 250g hopper up top, and a grounds bin (or filter basket) below.

Nothing here is aimed at the espresso crowd, and nothing is trying to be.

That positioning lines up with Cuisinart's wider catalogue, and the CBM-20 sits comfortably between their cheaper DBM-8 blade-adjacent model and the pricier CBM-22. If you drink drip, pour-over, or French press, and you want a set-and-forget hopper machine that grinds into a bin at the press of a button, this is squarely in the wheelhouse.

Grind quality

For a 40mm steel conical at this price, the particle distribution is acceptable rather than impressive.

Multiple Best Buy owners describe grinds that are "fairly evenly" produced, and the Cuisinart marketing claims "uniform" output, but the burrs are small enough that you'll see a meaningful spread of fines and boulders at the coarser end of the range. For V60 or Chemex, it produces a workable bed.

For French press, you'll get a consistent coarse grind without the dust you'd see from a blade grinder.

Stepped adjustment with 18 stops is enough range to find a setting that works for each brew method, but the jumps are coarse.

The grinder does claim an espresso setting, though this should be treated as advisory only — without fine pitch adjustment and with a 100W motor, pulling a clean modern espresso shot consistently isn't realistic. Treat the fine end as a turbo-charged AeroPress or moka option, nothing more.

Build and daily workflow

The unit is a plastic-and-stainless skin over a relatively light internal chassis, weighing 1.7kg. It feels closer to a small kitchen appliance than to a piece of coffee gear, which is exactly the trade-off the price demands.

Multiple long-term owners on Best Buy report solid reliability over months of daily use, though one noted the cord storage is fiddly to close with the cable inside.

Daily use is straightforward: fill the 250g hopper, select the number of cups (1–14, or manual mode), and the grinder runs until the chamber is full. The grounds bin is removable with a lid, so you can dose into a filter or scoop out what you need.

The interface is a simple LCD with a few buttons — no app, no grind-by-weight, no profiles.

One real friction point: static and spillage. The spec sheet lists no anti-static treatment, and owners report grounds clinging to the lid and a little mess when pulling the bin out. It's manageable but real, especially on the finer filter settings.

Noise and footprint

At 450 rpm with a 100W motor, the CBM-20 is loud by enthusiast standards. Several Best Buy reviewers flagged it as the kind of grinder that will wake the household. It's not a Baratza Encore in terms of refinement, but it's not a grinder that hides either.

Footprint is reasonable at roughly 8.7" wide by 14" tall, and the bean hopper is removable for storage, which helps in small kitchens.

How it compares at the price

In the $80–$100 range, the most obvious alternatives are the Baratza Encore and the Breville Smart Grinder Pro. The Baratza Encore uses a slightly larger 40mm conical with stepless micro-adjustments, which gives meaningfully better repeatability for pour-over, and has stronger long-term parts support.

The Breville Smart Grinder Pro adds a digital timer and a larger burr, but its stepped dial and harder-to-clean chute make it more of a feature comparison than a quality one.

For someone who wants absolute grind consistency in this bracket, neither Cuisinart leads — but the CBM-20 holds its own on features-per-dollar, particularly with the cup-count presets and the direct-grind-into-filter workflow.

For purely manual, single-dose use, something like the 1Zpresso K-Ultra plays in a completely different category, with hand-grinding in exchange for far better grind quality.

Who should buy it

Buy the CBM-20 if you want a low-friction, hopper-fed electric grinder for daily drip or pour-over, you don't intend to pull espresso, and you'd rather spend under $100 than chase marginal particle distribution. Skip it if grind consistency is the priority, if you want stepless adjustment, or if a quiet machine matters to your household.
