Fiorenzato Pietro (M-Modal Burrs)

What it does well

The burrs are the draw. Per Espresso Parts, their "unimodal curve reduces the concentration of fine particles and has a high peak of boulders," a profile aimed at extracting more flavor from filter brews. The page lists 58 mm burrs, large for a hand grinder.

The layout is meant to cut retention. Espresso Parts says vertical positioning "uses gravity to eliminate retention," and that the handle position increases leverage. The same page says the burr chamber releases with a push button and no tools, and the hopper and catch cup have airtight seals.

Adjustment is fine. The external dial moves about 15 microns per click, per Espresso Parts. That is stepped adjustment with enough resolution for pour-over and AeroPress.

It is easy to store. The lever retracts, and the page lists a size of 8.2 x 4.5 x 3.1 inches. A stabilizing baseplate, dosing funnel and cleaning brush come with it.

Forum posters rated the taste. In the launch thread, one poster wrote that "the taste was excellent" for a versatile hand grinder, before saying the user experience was "90% there." That comment came from an early impression of the grinder.

Where it falls short

It does not do espresso. Espresso Parts is plain about that, and the finder rates espresso at 0. Buyers who want one hand grinder for both should look at the multipurpose B-Modal burr set instead. Espresso Parts says the multipurpose burrs "grind for filter AND espresso."

Stability was an early complaint. In the Home-Barista launch thread, one poster said the grinder was "just missing some form of a stabilizing base," and another said it did not stay put under grinding. The current product page lists a "non-slip base + included stabilizing plate," so Fiorenzato appears to have answered, though no owner confirmation turned up.

It is heavy. Espresso Parts lists 3.3 lb (1.5 kg), and the casing is aluminum with a silicone base. A traveler may not want it in a bag.

Opinion was divided at launch. Forum posters in the same thread argued over whether the design was good value and whether critics had used it. Most posts predate wide ownership, so they are weak evidence either way.

Specifications vary slightly: the spec table lists a body of plastic and aluminum, while the description says "solid food-certified aluminum."

Who should buy it, and who shouldn't

Buy it if you brew pour-over, AeroPress, drip or French press and want a large flat burr hand grinder with low fines in the profile. It suits someone who grinds one or two cups at a time.

Skip it for espresso. Skip it too if you travel light: the weight and the baseplate are not made for a pack.

How it compares

The Pietro with B-Modal burrs is the multipurpose version. The 1Zpresso J is rated 1/2/3 here and is tagged for travel. The Timemore Chestnut C3 Max is rated 0/2/2 here, a lower-cost option. The grinder finder lets you sort them.

Owning it

Tool-free burr removal makes cleaning quick, and our guide to cleaning a hand grinder covers the routine. Espresso Parts says most items carry a 365-day guarantee for refunds or replacements, and equipment has a limited warranty linked from the page; the term is not stated there.

If you buy the M-Modal unit now, Espresso Parts says it only carries the Pro Brewing version as a complete unit, with multipurpose burrs sold separately.
