Cuisinart DBM-8 Supreme Grind: Everything You Need to Know
The Cuisinart DBM-8 Supreme Grind Automatic Burr Mill is one of the bestselling coffee grinders in its price range, typically landing between $45-65. It's been on the market for years, has tens of thousands of reviews, and sits at the most common entry point for people moving from blade grinding to burr grinding.
If you're trying to figure out whether it's the right grinder for you, or whether you've been using it for a while and want to know how to get more out of it, this covers the full picture. I'll go through what the DBM-8 actually does, where it performs well, where it falls short, and how it compares to other grinders you might be considering.
What the Cuisinart DBM-8 Is
The DBM-8 is an automatic electric burr grinder. It uses a pair of flat burrs to mill coffee beans into grounds, which is a fundamentally better approach than blade grinding. With blade grinding, a spinning blade chops beans unevenly, giving you a mix of coarse chunks and fine dust. With burr grinding, beans are crushed between two abrasive surfaces, producing much more consistent particle sizes.
The "automatic" part means it has a built-in timer that lets you set a grind dose (8-12 cups in labeled increments), press the button, and walk away. It stops grinding when the timer runs out. You can also stop it manually mid-cycle.
Key Specs
- 18 grind settings (very fine to very coarse)
- Grind directly into a portafilter or into the removable grounds bin
- 8 oz bean hopper
- 1-12 cup timer setting
- Around 200 watts
- Dimensions: roughly 6 x 10 x 11 inches
Grind Settings: What They Actually Cover
The 18 settings span from very fine (labeled for espresso) through extra coarse (labeled for French press). In practice, the useful range breaks down like this:
| Settings | Use |
|---|---|
| 1-4 | Very fine, nominally espresso |
| 5-8 | Fine to medium-fine, drip coffee, pour-over |
| 9-12 | Medium, standard drip |
| 13-16 | Medium-coarse, Chemex, coarser drip |
| 17-18 | Coarse, French press |
The sweet spot for the DBM-8 is the middle range (settings 7-13) for standard drip coffee. This is where it produces its most consistent grounds and where the majority of buyers use it.
What the DBM-8 Does Well
Budget Burr Grinding
The DBM-8's primary job is moving you from blade grinding to burr grinding at a low entry price. On that measure, it succeeds. Drip coffee made with DBM-8 grounds is noticeably more consistent and cleaner in flavor than the same beans ground in a blade grinder. The improvement is real and repeatable.
Drip Coffee Performance
For auto-drip coffee makers (Cuisinart, Breville, OXO, Mr. Coffee), the DBM-8 produces results that work well at settings 8-12. If you drink 8-12 cups a day from a drip carafe machine, the DBM-8 is a practical tool sized appropriately for that use.
Convenience Features
The grind-by-cup timer is genuinely useful for consistent morning routines. Once you find the right setting for your preferred strength, you can program the dose and get consistent cups without weighing every day.
The portafilter notch lets you grind directly into an espresso portafilter, which reduces the mess of transferring grounds. This works better in theory than practice for espresso (more on that below), but for Moka pot users it's a convenient feature.
Price
At $45-65, the DBM-8 is competitive against any burr grinder at this price. It's not the cheapest option, but it's one of the most established and consistently available ones.
Where the DBM-8 Falls Short
Fine Grinding and Espresso
The DBM-8 has a settings range that includes "fine" and "very fine" positions, but the reality of espresso-quality grinding at this price is disappointing. The burrs don't produce enough fine-end consistency for dialing in espresso on a semi-automatic machine. The particle distribution at settings 1-4 is wide, meaning you get a range of particle sizes rather than a tight cluster at the espresso target.
This isn't unique to the DBM-8; it's a limitation of any burr grinder under $100-150 for espresso purposes. But worth knowing before you assume the fine settings will handle your espresso machine.
Grounds Retention
The DBM-8 retains a meaningful amount of grounds in the exit chute between grinds. If you change your grind setting or haven't used the grinder in a day or two, the first grams out will be old grounds from the previous session. For drip coffee drinkers, this is a minor issue. For specialty brewing where dose precision matters, it's more significant.
Noise
The DBM-8 runs at high RPM and is noticeably noisy. At 80-85 dB, it's louder than slow-speed grinders like the Capresso Infinity (450 RPM vs. The DBM-8's higher motor speed). This matters if you're grinding early morning while others sleep.
Build Durability
The DBM-8 is primarily plastic construction. The bean hopper, grounds bin, and most of the exterior are plastic. This isn't unusual at the price point, but it contributes to a less premium feel and more wear over time compared to stainless steel or aluminum-body grinders.
Burr grinders in this category (under $60) generally have a realistic lifespan of 3-5 years with daily use before motor or burr issues appear. The DBM-8 is consistent with that pattern.
Cuisinart DBM-8 vs. Competitors
vs. Baratza Encore ($170)
The Encore has 40 settings vs. 18, higher quality burrs, significantly better fine-end consistency, quieter operation, and better long-term durability. It costs 2-3x more. If you're willing to spend $170, the Encore is clearly better. At $45-65, the DBM-8 is the right price for what it delivers.
vs. Capresso Infinity ($100-130)
The Capresso Infinity's slow-speed motor produces less heat and fewer fines at comparable settings. For drip and pour-over, the Infinity outperforms the DBM-8. The Infinity is $50-80 more expensive. If your budget is $100+, the Infinity is the better buy.
vs. OXO Brew Conical Burr Grinder ($100)
The OXO uses conical burrs, 15 settings with labeled brew methods, and is significantly quieter than the DBM-8. For drip coffee use, the OXO produces cleaner results. At $100 vs. The DBM-8's $45-65, you're paying for measurably better performance.
vs. Hario Mini Mill Hand Grinder ($40-50)
Here's an interesting comparison. A Hario Mini Mill hand burr grinder at $40-50 produces better-tasting drip coffee than the DBM-8 because its burrs are more consistent. You're trading electric convenience for hand-grinding time. For 1-2 cups daily, the Hario wins on value and cup quality. For 4+ cups or for people who can't use a hand grinder, the DBM-8 makes more sense.

Tips for Getting the Most Out of Your DBM-8
Find Your Setting and Mark It
Test the DBM-8 at settings 8, 10, and 12 with your normal brewing method. Make a cup at each setting and taste the difference. When you find the right one, mark it with a small sticker or tape so you always return to the same position without guessing.
Use the Right Grind-by-Cup Increment
The cup timer markings on the DBM-8 are calibrated for standard cups (about 5-6 oz per cup in Cuisinart's measurement). Actual coffee mugs are usually 8-12 oz. If you're making a 12-cup batch in an actual 12-cup carafe, you likely need to set the timer at 12 cups (the max) and possibly run it twice.
Clean Regularly
Coffee oils accumulate on the burrs and chute. Monthly cleaning keeps the machine performing well and prevents stale flavors from contaminating fresh beans. Remove the top burr (unscrew it) and brush off grounds with a stiff brush. Wipe down the chute and grounds bin.
Don't Grind Dark Oily Roasts Constantly
Very dark, oily roasts coat the burrs in oil that accumulates quickly. If you drink dark roast, clean the grinder every 2 weeks rather than monthly.
FAQ
How do you clean the Cuisinart DBM-8?
Remove the bean hopper and top burr. Brush the burr plates with a stiff cleaning brush (Cuisinart includes one; use it). Wipe the chute and grounds bin with a dry cloth. Run grinder cleaning tablets monthly. Avoid washing the burrs with water; they can rust.
What grind setting should I use for drip coffee?
Settings 8-10 work for most auto-drip machines. If your coffee tastes bitter, go one step coarser. If it's weak or sour, go one step finer. Taste the result before making larger adjustments.
Can the Cuisinart DBM-8 grind for espresso?
Technically the fine settings exist, but performance for espresso dial-in is limited. Fine-end consistency isn't tight enough for quality espresso on a non-pressurized semi-automatic machine. For pressurized portafilter machines or very basic espresso setups, you can get workable results.
Is the Cuisinart DBM-8 loud?
Yes, louder than average. If you're grinding early morning with people sleeping nearby, the noise level is significant. Consider the Capresso Infinity or OXO Brew if quiet operation matters.
The Bottom Line
The Cuisinart DBM-8 is the right grinder for a specific buyer: someone who wants to upgrade from a blade grinder, makes auto-drip coffee primarily, and wants reliable performance at the lowest reasonable price for a burr grinder.
It's not the right grinder for espresso enthusiasts, specialty coffee obsessives, or people who want quiet operation. At $45-65, it delivers a genuine improvement over blade grinding with the convenience features that make daily drip coffee effortless.
If you can spend $100, step up to the OXO Brew or Capresso Infinity. Both perform better across every metric. But if the budget caps at $60, the DBM-8 is the most established and field-proven choice in its price range.
