Still Spirits Distiller's Enzyme Alpha Amylase 12gr - distillers

Still Spirits Distiller's Enzyme Alpha Amylase is a 12g sachet of the first enzyme in a grain mash. Still Spirits describes it as "a bacterially-derived enzyme which breaks down starch into dextrins and simple sugars during mashing". One sachet treats up to 7.5kg of starch for a 25 litre wash.

What it does

Raw starch is not fermentable. Alpha amylase works hot and cuts the long starch chains into shorter dextrins, thinning the gluey cooked mash into something a yeast can eventually use. It is step one; the glucoamylase then turns those dextrins into fermentable glucose at a lower temperature.

How to use it

Bring the starch and water to the boil, simmer for 30 minutes, cool to 80 degrees or just under, stir in the enzyme and let it stand for 60 minutes. It works between 65 and 80 degrees. Then cool to 65 or below for the glucoamylase. Still Spirits carries a warning on the pack: the powder may cause allergy or asthma symptoms if inhaled, so open it away from your face.

When you need it

Any wash built on grain, potato or other starch. Sugar and dextrose washes do not need it.
