It is well rated by buyers, with dozens of ratings, which makes it the best rated low retention espresso grinder with 83 mm burrs we found.

Highlights:

• 83 mm burrs, the largest here.

We did not do hands on testing. We picked only grinders whose listings state low or near zero retention, then compared brew quality (burr type and size), temperature stability (keeping grounds cool and consistent), ease of use, cleaning and build quality. Retention figures are the makers' claims. We read low retention espresso grinder reviews on Amazon as star ratings and counts only. If you have searched for best low retention espresso grinder reddit, our practical answer stays the same: stated retention, burrs and adjustment come first.

Type

• Single dose: Load one shot's beans at a time; all three picks. See our best single dose espresso grinder guide.
• Flat burr: Parallel rings, like both MiiCoffee grinders.
• Conical burr: A cone inside a ring, like the AMZCHEF.
• Stepless: Infinite adjustment, as on the DF64 II.
• Doserless: Grinds on demand with no doser chamber.
• Manual: Hand grinders; see our best hand espresso grinder guide.
• Commercial: Café grinders built for volume, usually with hoppers.
• Low retention: Keeps leftover grounds to a fraction of a gram.
• Budget: Under $150; see our best budget espresso grinder roundup.
• 64mm: The DF64 II's burr size, a popular home flat burr size.

Features worth paying for

• Timer: The best low retention espresso grinder with timer here is the AMZCHEF; single dose grinders usually stop when the beans run out.
• Grind by weight: None of our picks does this; you weigh beans before grinding instead.
• Portafilter holder: The DF64 II has a portafilter rest, but MiiCoffee recommends the dosing cup.
• Bellows: A puffer that pushes out retained grounds; MiiCoffee instead supplies a blow out funnel.

Brew temperature (195-205°F) & SCA certification

Grinders do not heat water; your espresso machine handles the common 195 to 205°F range. The grinder's part is an even grind so that water extracts evenly. None of our picks claims SCA certification.

Water reservoir, filters & descaling

A grinder has no water parts to descale. Its equivalent is brushing burrs and clearing the chute, which is easier on low retention designs.

Counter footprint

Single dose grinders are compact because they have no big hopper. Leave room in front for a dosing cup and a scale. The 58 mm dosing cups suit Gaggia Classic and Rancilio Silvia baskets, and the AMZCHEF's 51/54 mm stand makes it a best low retention espresso grinder for Breville Bambino owners (54 mm).

How much should you spend?

• Under $150: Single dose conical grinders like the AMZCHEF.
• Under $200: More compact single dose models; the best low retention espresso grinder under 200 tier.
• Under $300: Stepless conical models; the best low retention espresso grinder under 300 tier.
• Under $500: 64 mm and entry 83 mm flat burr grinders like the DF64 II and DF83 Gen 2.
• Under $1000: Variable speed and premium burr sets.

A low retention espresso grinder is built for weighing beans in and getting the same weight out. That makes bean switching easy and dosing precise.

If you drink one espresso blend and value speed, a hopper grinder is simpler. For everything else, see our best espresso grinder guide.

What is the best low retention espresso grinder?

The MiiCoffee DF64 II is the best low retention espresso grinder for most home baristas. It pairs 64 mm flat burrs with stepless adjustment and a stated retention under 0.1 gram, and it is well rated by buyers. The AMZCHEF is the budget pick, and the DF83 Gen 2 is the upgrade.

Are low retention espresso grinders worth it?

Yes, if you switch beans or want exact doses. Low retention means old grounds do not end up in your next shot and you waste fewer grams purging. If you drink one bean and prefer pressing a button, a hopper grinder is more convenient.

How long does an espresso grinder last?

No official lifespan figure is published. Burrs wear with use and eventually need replacing, and motors age with heavy grinding. Buying a grinder with replaceable or upgradable burrs, cleaning it regularly and keeping moisture out help it last longer.

Is an espresso grinder worth it?

Yes, if you own an espresso machine. Espresso needs a fine, even grind adjusted in small steps, which preground coffee cannot give you. Grinding fresh right before brewing keeps aroma and sweetness that preground coffee loses within days.

How do you clean an espresso grinder?

Unplug the grinder, remove any beans and open the burr chamber if your model allows. Brush the burrs, chute and outlet, then use the blow out funnel or knock tool to clear fines. Avoid water on burrs unless the maker says it is safe.

What is the most reliable espresso grinder brand?

No single brand is the most reliable for everyone. MiiCoffee lists a one year warranty on its DF grinders, and larger brands such as Baratza are known for spare parts. Compare warranty, parts availability and rating pool size before you buy.

The MiiCoffee DF64 II is our best low retention espresso grinder 2026 pick and the top rated low retention espresso grinder by rating pool. The AMZCHEF is the budget choice under $150, and the DF83 Gen 2 is the premium upgrade. Check prices on Amazon for the best low retention espresso coffee grinder for your setup.
