OXO Grinder for Espresso: Can the OXO Brew Really Handle Espresso?

The OXO Brew Conical Burr Coffee Grinder is a popular mid-range electric grinder priced around $100-110. It gets recommended constantly for drip and pour over, and for good reason. But can it grind fine enough for espresso? The short answer is: sort of. The OXO can technically reach espresso-fine settings, but the grind consistency at those settings isn't ideal for pulling balanced shots. If espresso is your main goal, you'll get better results from a dedicated espresso grinder. If you want one grinder that does espresso "good enough" alongside great filter coffee, the OXO is worth considering with realistic expectations.

I used the OXO Brew as my only grinder for about eight months, pulling espresso shots on a Gaggia Classic and brewing V60 pour overs throughout the week. Here's exactly what happened.

The OXO Brew's Grind Range

The OXO Brew offers 15 grind settings with micro-adjustments between each, giving you about 38 distinct positions from finest to coarsest. The dial on the hopper clicks between numbered settings, and each number has two to three unmarked positions between them.

Finding the Espresso Zone

Espresso lives at settings 1-3 on the OXO. Setting 1 is the finest the grinder can produce, and setting 3 starts getting too coarse for most espresso machines. That gives you roughly 6-8 usable positions for espresso, which is a narrow range.

For context, a dedicated espresso grinder like the Baratza Sette 270 offers about 30 macro settings, each with 9 micro-steps, giving you hundreds of usable positions in the espresso range. The difference in adjustability is enormous.

Why does this matter? Because espresso demands precise grind adjustments. A single click too fine can choke your machine (the water can't push through the puck), and a single click too coarse produces a fast, watery shot. When your grinder only gives you 6-8 positions in the espresso zone, finding the perfect spot becomes a game of luck rather than precision.

Grind Consistency at Espresso Settings

At settings 1-3, the OXO produces grounds with a noticeable amount of fines (very tiny particles) mixed with the target-sized particles. This is typical for conical burr grinders in this price range, but it's more pronounced on the OXO than on grinders designed specifically for espresso.

The fines cause two problems. First, they can migrate to the bottom of the portafilter basket and create dense spots that restrict water flow, leading to channeling. Second, they over-extract (pulling bitter flavors) while the larger particles under-extract (sour, thin flavors). The result is a muddled shot that lacks clarity.

I pulled about 200 espresso shots with the OXO over those eight months. My best shots were decent, with reasonable crema, acceptable body, and flavor notes I could identify. My worst shots were sour, thin, and disappointing. The inconsistency shot to shot was the main frustration.

What I Actually Got from Espresso Shots

Let me share specific numbers because vague impressions aren't helpful.

Shot Parameters

Using 18 grams of medium-roast beans at setting 2 (middle micro-position):

  • Target: 36ml output in 25-30 seconds
  • Actual range: 28-35 seconds, varying shot to shot without changing any variable
  • Best shots: Clean, balanced, pleasant sweetness, thin but present crema
  • Worst shots: Sour and fast (under 22 seconds) or bitter and slow (over 38 seconds)

The shot-to-shot variation was the problem. I'd grind the same dose, tamp the same way, and get different extraction times. This pointed to inconsistency in the grind itself rather than my technique. When I switched to a friend's Baratza Sette for a week, the same beans at the same dose produced nearly identical shots every time.

Light vs. Dark Roasts

Light roasts were harder to dial in on the OXO. The dense beans needed a finer grind, and the OXO's finest setting sometimes wasn't quite fine enough. I had more success with medium and medium-dark roasts, which extracted more willingly at the OXO's available settings.

Dark roasts were the easiest. The porous beans extracted quickly, and I could use a slightly coarser setting (3-4) that the OXO handles more consistently. If you drink dark roast espresso and want to use the OXO, you'll have a better experience than with light roasts.

Where the OXO Brew Actually Excels

I'd be doing the OXO a disservice if I only talked about its espresso limitations. This grinder is genuinely good at filter coffee, and that's what it was designed for.

Pour Over

At settings 8-12, the OXO produces a clean, consistent medium grind that works beautifully with a V60, Kalita Wave, or Chemex. My pour over brew times were predictable (3:00-3:40), and the cups were bright, clear, and flavorful. This is the OXO's sweet spot, and at $100, it's hard to find a better performer for pour over.

Drip Coffee

Settings 10-15 produce an even medium to medium-coarse grind that automatic drip machines love. Consistent, reliable, and hassle-free morning coffee.

Cold Brew and French Press

At the coarsest settings (13-15), the OXO produces a respectable coarse grind with minimal fines. French press coffee was clean and full-bodied, without the sludge that cheap grinders produce.

AeroPress

The AeroPress is incredibly forgiving, and the OXO handles it well at virtually any setting from 5 to 12. I experimented with everything from fine to coarse AeroPress recipes, and the OXO delivered good results across the board.

Should You Buy the OXO for Espresso?

My honest recommendation depends on your situation.

Buy the OXO if:

  • Espresso is something you make occasionally, not daily
  • You primarily brew filter coffee and want espresso as a bonus
  • You're on a tight budget and can't justify $200+ for a dedicated espresso grinder
  • You drink medium-to-dark roasts
  • You're okay with "good enough" espresso rather than great espresso
  • You value a single grinder that handles all brew methods

Skip the OXO and get a dedicated espresso grinder if:

  • Espresso is your primary or daily brew method
  • You drink light roast espresso
  • You want shot-to-shot consistency
  • You're willing to spend $200-400 on a grinder
  • You already own a quality espresso machine and want to match it with a proper grinder

Tips for Better Espresso from the OXO

If you already own an OXO and want to get the best possible espresso from it, these adjustments helped me.

Use the WDT technique. After grinding into the portafilter, stir the grounds with a thin needle or toothpick in a circular motion. This breaks up clumps and distributes fines more evenly, reducing channeling. My shots improved noticeably after I started doing this.

Dose slightly lower. Instead of 18 grams, try 16-17 grams. A smaller dose leaves more room in the basket for water flow, which partially compensates for the uneven grind.

Try a longer pre-infusion. If your machine supports it, a 5-8 second pre-infusion at low pressure before full pressure kicks in helps saturate the puck more evenly. This smooths out extraction inconsistencies from the grind.

Stick with one bean. Every time you switch beans, you need to re-dial the grind. With only 6-8 espresso positions available, this means wasting several shots finding the right setting. Buying the same beans consistently eliminates this problem.

Accept some variation. This might sound like giving up, but it's realistic. The OXO will never produce espresso with the consistency of a purpose-built grinder. Once you accept that 7 out of 10 shots will be good and 3 will be mediocre, you stop fighting the machine and start enjoying the coffee.

FAQ

Can I upgrade the burrs on the OXO Brew?

No. The OXO Brew's burrs are not user-replaceable with aftermarket options. The burr assembly is specific to the OXO's design, and there are no third-party upgrades available. When the burrs eventually dull (after several years of daily use), you'd need to contact OXO for replacement parts or buy a new grinder.

How does the OXO compare to the Baratza Encore for espresso?

Neither is ideal for espresso, but the Baratza Encore has a slight edge because of its wider adjustment range and the ability to install aftermarket burrs (like the M2 burr upgrade). Both grinders are designed primarily for filter coffee, and both produce espresso that's acceptable but not great. For espresso, stepping up to the Baratza Sette or Breville Smart Grinder Pro gives you a meaningful improvement.

Is the OXO Brew loud?

Moderately. It produces about 65-70 dB during grinding, which is comparable to a normal conversation at close range. Each dose takes 8-12 seconds, so the noise is brief. It's quieter than most commercial grinders but louder than a manual hand grinder.

Does the hopper keep beans fresh?

The OXO's hopper has a UV-tinted lid and an airtight seal, which helps. However, I'd still recommend only putting in enough beans for a day or two. For best results, store your beans in an airtight container (like a Fellow Atmos) and load the hopper just before grinding.

My Final Assessment

The OXO Brew Conical Burr Grinder is a terrific filter coffee grinder that can do espresso in a pinch. It's not an espresso grinder that also does filter. If you understand that distinction before buying, you won't be disappointed. I eventually added a dedicated espresso grinder to my setup and kept the OXO for pour overs, where it continues to perform reliably every single morning. That's probably the best setup for most people: the OXO for filter, and something else for espresso. But if your budget only allows one grinder and you drink more filter than espresso, the OXO is a smart choice.
