The Sweetened Nutrient Medium Formed Prior To Alcoholic Fermentation Is Called

A: Mash
B: Wash
C: Malt
D: Wort

The answer is: D

Explanation

The sweetened nutrient medium formed prior to alcoholic fermentation is called D: Wort.

Wort is a sweet liquid that is created during the brewing of beer. It is made by soaking crushed malted barley in hot water to extract the sugars, proteins, and other components of the grain. The liquid is then boiled with hops to impart bitterness and flavor to the final product.

After the wort has been boiled and cooled, it is inoculated with yeast to begin the process of alcoholic fermentation, in which the yeast consumes the sugars in the wort and produces alcohol and carbon dioxide as byproducts.

Mash is a term used to describe the mixture of crushed grains and hot water that is used to create the wort in the brewing process. Wash is a term used to describe the liquid that remains after the wort has undergone alcoholic fermentation. Malt is the term used to describe grain that has been soaked in water and allowed to germinate before being dried and used in brewing.
