To use this – Make up a soup with 15 L of water and 4 kg of starch. Add the 4 g sachet of Alpha Amylase and keep at 70 degrees C overnight and your starch will be converted to sugar. Measure using a refractometer or simply taste for sweetness. If you want a higher temperature, our Alpha Amylase unlike many others can handle temperatures up to 85 degrees before denaturing. To be used with Distiller’s Yeasts when starch is used in your recipe.
