The copper coil has rapid thermal conductivity and has a large contact area with the coolant, providing a lower distillation temperature. The rubber pad under the condenser can insulate and accelerate cooling.· Easy to Operate: The moonshine 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. · Durable & Tight Seal: Unlike regular tubes, we use food-grade silicone tubes, which are flexible and tough, and are not easy to bend to ensure a good seal. Four buckles and silicone gaskets inside the lid help to seal tightly. In addition, the package has a one-way exhaust valve, which can be easily used during the fermentation process. · Versatile Application: There are many ways to use our alcohol still kit. According to your preferences, you can make Whiskey, Wine, Brandy, Rum, Tequila, Vodka, Water Distiller, Ethanol, Essential Oils, etc. The thickened bottom allows various heating methods, including gas stoves, firewood, electric ceramic heaters, etc.
