Does hops fermented noodles contain alcohol?

"Bread made of hops contains a certain amount of alcohol.

Bread, biscuits and snacks in Russia are all cultivated and domesticated by hops (Leba flowers), and then hops yeast is mixed with corn flour or rye flour and dried with grains. Wild hops yeast can be preserved for a long time (2-3 years or longer, without refrigeration).

This way is a differentiated way to distinguish wild yeast from Western Europe, Northern Europe and the United States, which must be refrigerated or frozen. This unique way is also the most prominent feature of Russian cake culture. Leba in Russia was fermented with hops yeast for three times.
