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](https://www.trendhunter.com/trends/single-shot-coffee-grinder). 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.
