Cup profile
- With Pro Brew it's the most unimodal hand grinder Lance Hedrick has measured. The cup is clear, silky and balanced, and sifting out fines makes it hollow 4:05.
- Pro Brew gives high clarity, sweetness and texture, with a wider sweet spot than SSP multi-purpose 64 mm burrs 2:02. With ultra-light roasts it has better texture and clarity than the Femobook A4Z 0:00.
- The multi-purpose burr makes robust traditional espresso, similar to a Eureka Specialità but higher quality, and it also does pour-over 15:35.
Strengths
- Lance Hedrick says Pro Brew beat his favourite filter hand grinders and an SSP-equipped Fellow Ode in blind cupping and particle tests 1:01.
Weaknesses
Verdict
In 2023 Lance Hedrick named it the best filter hand grinder, while pointing out his involvement 1:01. His 2024 tier list gave both burr versions a B 9:07. In 2025 it was his top filter pick, on some days ahead of the EG-1 2:02, and a fantastic traditional espresso grinder with multi-purpose burrs 15:35.
Daddy Got Coffee's take
- In 2023 he found the cups superb and the ergonomics frustrating. The B-Modal burr gives balanced espresso. The M-Modal Pro Brew gives some of the cleanest filter he has tasted, but its espresso is thin and hard to dial in 0:00 5:35.
- From 2024 to 2026 it was still his favourite cup for clarity. Expect muddy, astringent, slow brews until you've put about 3 to 5 kg through it to season the burrs 4:43 14:57 10:16.
