DF is a family of single-dose grinders with flat and conical burrs, made in China. The official DF64 page on dfgrinders.com states «Manufactured in: China» and notes that the same grinders are authorised for sale under private labels such as Turin, MiiCoffee, G-IOTA and Solo, identical except for the name on the label. No official page names the factory behind them or gives a founding year: dfgrinders.com itself says it handles warranty support directly so that customers never have to go through overseas manufacturers. A second site, df64coffee.com, calls itself «DF64 Official Dealer» and does not name the manufacturer either.
dfgrinders.com describes itself as an online retailer focused exclusively on DF grinders, serving the US market: orders ship from a warehouse in Carrollton, Texas, and its mailing address is in Mississauga, Ontario (Canada). The stated warranty covers defects in materials and workmanship under normal home use for one year, fulfilled in-house, and can be extended to two or three years through the Premium Protection Program. The terms carry real conditions: single-dose use only, with cooling time between doses, cleaning with a dry cloth only, and operation on standard US household voltage. Buyers who purchased elsewhere are referred to their own retailer.
The range listed on the site covers the DF54 (V4), DF64 Gen 2, DF64V Gen 3, DF83 (V3) and DF83V, with 54, 64 and 83 mm flat burrs, plus the DC63 with conical burrs. Bodies are powder-coated aluminium; the grind chute and dosing cup are food-safe plastic, the bellows silicone and the lid wood. Stock burrs are either plain stainless steel or stainless steel with a titanium carbonitride coating (Red Titanium), and for the 64 mm platforms the site also sells LeBrew and SSP aftermarket burrs. The site claims near-zero retention thanks to a short, direct chute, a tilted burr chamber and the bellows, along with stepless grind adjustment.
