Can Angie's liqueur koji still be used after its expiration date?
You can't. Angel's starter has passed the shelf life, and its taste and function have changed. If expired koji is used, there will be some harmful substances in yellow rice wine, which will have an impact on people's health after drinking. Angie's distiller's yeast has expired and can't be used. Distiller's yeast is to transplant conidia of Aspergillus into boiled white rice, and then keep warm, so that hyphae will grow vigorously on rice grains.
