Why is it permitted to drink wine on Passover when it is fermented with yeast? Isn't yeast forbidden on Passover?


Of the hundreds of species of yeast, the Passover prohibition only applies to yeast which is a product of one of the following five grains: wheat, barley, oat, spelt, or rye. Yeast which is the product of grapes, or its sugars, is not considered chametz (leavened food).
