Mixing Instructions: Shake well before use. Use 1 capful when using the Air Still, 4.9 L Boiler, or other smaller stills. Use 3 capfuls for the T500 and other large stills. This releases carbon dioxide & stops the foaming of unfermented sugars during distillation. Since the bottle contains 50ml of food-grade silicone surfactant this should be enough for the distillation of 67 liters of wash
