Still Spirits Glucoamylase Enzyme 12g | Distilling Enzyme

Glucoamylase Enzyme for Grain and Starch Mashes

Still Spirits Glucoamylase is a powdered, fungal-derived enzyme used to convert short-chain dextrins in liquefied starch and grain mashes into simple, fermentable sugars.

It improves starch conversion and fermentability, helping distilling yeast access more of the available sugar. Glucoamylase can be used after mashing or added during fermentation for simultaneous saccharification and fermentation.

Each 12g sachet treats up to 7.5kg of liquefied starch in a fermentation volume of up to 25 litres.

Why You'll Love It

• Suitable for up to 7.5kg of liquefied starch

• Treats fermentation volumes up to 25 litres

• Can be used after mashing

• Can also be added during fermentation

• Suitable for grain, corn, rice and other starch-based washes

• Convenient single-batch 12g sachet

What Does Glucoamylase Do?

Glucoamylase breaks down short-chain dextrins and other complex carbohydrates into smaller, fermentable sugars such as glucose.

This allows the yeast to ferment more of the available carbohydrates, helping produce:

• Greater starch conversion

• Improved attenuation

• A drier finished wash

• More fermentable sugar for the yeast

• Better use of grain and starch ingredients

How Much Does One Sachet Treat?

One 12g sachet is sufficient for:

• Up to 7.5kg of liquefied starch

• Fermentation volumes up to 25 litres

How to Use Glucoamylase After Mashing

1. Complete the starch liquefaction or grain-mashing process.

2. Cool the liquefied starch slurry or malted grain mash to 65°C or below.

3. Add the complete sachet of Glucoamylase.

4. Stir thoroughly to distribute the enzyme.

5. Cover and hold the mash between 50–60°C for approximately one hour.

6. Cool to the correct temperature before adding yeast and beginning fermentation.

Do not add the enzyme above 65°C, as excessive heat may reduce enzyme activity.

Can It Be Added During Fermentation?

Glucoamylase may also be added to the mash or wort together with the yeast for simultaneous saccharification and fermentation.

When using this method, maintain a fermentation temperature that is suitable for the chosen yeast. Always follow the temperature and dosage instructions supplied with the yeast.

Do I Need Alpha-Amylase as Well?

Glucoamylase works on starch that has already been gelatinised and liquefied.

When using unmalted corn, rice or other starch-rich ingredients, an Alpha-Amylase enzyme may be required first to liquefy the starch. Glucoamylase is then used to convert the resulting dextrins into fermentable sugars.

Malted grain contains natural enzymes, but additional enzymes may still be useful when working with high percentages of unmalted grain or when maximum fermentability is required.

What Mashes Can Glucoamylase Be Used With?

Still Spirits Glucoamylase is suitable for starch-based fermentations containing ingredients such as:

• Malted grain

• Corn or maize

• Rice

• Wheat

• Barley

• Rye

• Other properly gelatinised and liquefied starch sources
