Distilling Conditioner is an anti-foaming product, made of silicones and is suitable for human consumption.
Distilling conditioner reduces the chance of foaming in the boiler and promotes optimum distillation conditions. The wash can froth when boiling (this may be due to the presence of residual sugar not entirely fermented, or a wash not cleared). Froth can enter the column/condenser and then make its way through the output as undistilled liquid.
To help prevent foaming we recommend adding 4-5 capfuls (for brown spirit washes), or 3 capfuls (for other washes) of Still Spirits Distilling Conditioner.
