TUNI has introduced the G3 Flat Burr Coffee Grinder for the North American market — a home coffee grinding device featuring 64-millimetre stainless steel flat burrs and a stepless adjustment system with a whopping 100 distinct grind settings to make anything from Turkish coffee to French press.
TUNI's efficient G3 Flat Burr Coffee Grinder also includes a dual hopper design consisting of an 8.8-ounce container for daily convenience and a 1.7-ounce micro-hopper for single-dosing. The company boasts that its product comes with near-zero retention, which aims to prevent stale grounds from mixing with fresh beans.
Flat burrs are known to produce a more unimodal particle distribution compared to conical burrs, which reduces fine particles and allows the natural sweetness, floral notes, and bright acidity of specialty coffee to come forward more clearly.
