Still Spirits Distilling Conditioner is a defoaming agent to prevent foaming in the boiler!
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 foaming of unfermented sugars during distillation.
