Turin DF64 Gen 2 Review 2026: Tray Fixes the V5

Which DF64 is this review? This page covers the DF64 Gen 2, the current model with a single-dose tray.

The two share the same 64mm flat burrs, stepless collar, motor and ionizer, so the choice is about workflow rather than cup quality. The Gen 2 swaps the bellows for a tray, which removes a technique step from every shot.

• New buyer: choose the Gen 2. It costs about the same range and you skip the squeeze routine and most of the alignment fuss.
• Current V5 owner: only upgrade if the bellows routine genuinely irritates you or your unit never aligned well. A well-aligned V5 produces the same burr performance, so money is often better spent on aftermarket burrs or fresh beans.
• Trade-off: the Gen 2's gains are workflow and consistency of build, not a new grind profile. Expect a smoother morning, not a different espresso.

• 64mm flat burrs: Larger burrs grind the same dose with less heat build-up per gram and tend to give a narrower particle spread at espresso fineness. In practice that shows up as clearer, more distinct flavors, especially on light roasts. The trade-off is more fines than a dedicated brew grinder produces, which is why filter coffee is serviceable but not the strength.
• Stepless adjustment: There are no fixed clicks, so you can land on any grind size between two settings. Espresso is sensitive enough that a small nudge changes shot time noticeably, so this suits people who like to chase a precise target. The cost is patience: with no markings, you need your own reference mark, and returning to a previous setting after a trip to filter grinding is guesswork.
• Single-dose tray: You weigh your dose, grind it, and everything that went in comes out. That suits bean rotation and small bags, and it keeps stale grounds out of the chute. The trade-off is a few seconds of extra handling per drink compared with a hopper that fills a portafilter with one button press.
• Anti-static ionizer: Clumping is one of the main causes of uneven puck density. The ionizer helps in moderate humidity; in very dry rooms, a light water spritz on the beans is the usual fix.
• Slow motor: A 10-15 second grind per dose sounds long, but a slower motor also generates less heat and noise, which keeps the sound lower-pitched than fast grinders, though it is not silent.

The DF64 Gen 2 is a single-dose flat burr grinder. Two large flat burrs, 64mm across, face each other. Beans fall between the rings and are cut as the top burr spins. Wider burrs cut more beans per rotation, so the motor can run slower and cooler for a given output.

Flat burrs usually give a more uniform particle size, which makes espresso taste more defined and layered, with brighter acidity on lighter roasts. They also expose differences in beans more clearly than conical burrs.

The stepless collar lets you move between settings with no fixed steps, so you can fix a shot that runs a second too fast. Single-dose design means you weigh beans in and grind them out, keeping retention low and letting you switch coffees freely.

Who this mechanism suits: This is the grinder for people who already know their way around an espresso machine and want sharper flavor from lighter roasts. First-time buyers may prefer a simpler, numbered adjustment while learning.

The main issues are alignment, static, and dialing in.

• Burr alignment: a misaligned burr set makes uneven particles and a sour, thin shot. Check the gap and re-seat if needed.
• Static and clumping: RDT mist, then stir with WDT. A puck screen helps with even water flow. See channeling.
• No scale on the collar: mark your favorite settings with tape. Work from dialing in espresso.
• Retained grounds: brush out the chute and tray; the Gen 2 has no bellows.
• Sour or bitter shots: read sour espresso and bitter espresso before changing coffee.
• Upgrade path: aftermarket burrs and anti-static parts are common modifications.

• Eureka Mignon Specialita: choose it if you want a hopper-fed, stepless grinder with a more finished body and do not need a single-dose tray.
• Fellow Opus: a better pick if your coffee is mostly filter, with some espresso. Stepped adjustment is friendlier, but it is not an espresso specialist.
• Baratza Encore ESP: the simpler, lower-cost option for newer espresso drinkers who want fixed steps and less setup.
• Mavo Phantox Pro and manual grinders such as the 1Zpresso K-Ultra: relevant if you want to grind by hand and skip electric power entirely.
