Sufficient Capacity: This alcohol still provides you with a fermentation capacity of 3 gallons. Boiler barrel: 9.8' x 9.8' (25 x 25 cm), condenser: 7.9' x 4.3' (20 x 11 cm), thumper keg: 7' x 4' (18 x 10 cm), which can ferment up to 11.4 liters of raw materials. Perfect for family-together parties. All parts are made of food-grade materials, including silicone, stainless steel, and copper. Rapid Cooling: The distillery kit adopts an open cooling method. The copper coil has rapid thermal conductivity and has a large contact area with the coolant, providing a lower distillation temperature. A circulating water pump is attached to save cooling water. The rubber pad under the condenser can insulate and accelerate cooling. Easy to Operate: The alcohol still kit has a real-time thermometer on the lid, with a dual-display of Celsius and Fahrenheit, which is convenient for monitoring the temperature of the wine during the distillation process
