Japanese White Koji

Regular price $14.99

This White Koji is formulated specifically for brewing sour beer with citric acid.

Koji (Aspergillus luchuensis) is a fungus that is grown on rice during the Shochu making process and citric acid is naturally generated. Koji is grown on rice which breaks down starch in the rice to a more fermentable sugar source. Yeast can then use these sugars during fermentation to add a bright and refreshing citric acid character.

White Koji should be used at a rate of 20% - 25% of total grain in your recipe.
