Question 1

The name of the French chemist and biologist who made significant contributions to chemistry, medicine, and, indirectly, the food and beverage industry that have greatly benefited civilization.&#10;A) Albert Schmid&#10;B) Robert Mondavi&#10;C) Napoleon&#10;D) Louis Pasteur

Accepted Answer

Louis Pasteur was a French chemist and biologist renowned for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization, which have had a profound impact on medicine and the food and beverage industry.

Question 2

The unintentional natural process of fermentation&#10;A) precedes human history&#10;B) 10,000 B.C.&#10;C) 10 B.C.&#10;D) none of the above

Accepted Answer

Fermentation is a natural process that occurs without human intervention and has been happening long before recorded human history.

Question 3

Fermentation occurs in&#10;A) beers&#10;B) wines&#10;C) spirits&#10;D) all of the above

Accepted Answer

Fermentation is a process used in the production of beers, wines, and spirits, where yeast converts sugars into alcohol and other byproducts.

Question 4

Yeast consumes sugar and produces alcohol and carbon monoxide.

Accepted Answer

Yeast consumes sugar and produces alcohol and carbon dioxide, not carbon monoxide, through the process of fermentation.

Question 5

In general, wine is produced from grain.

Accepted Answer

Wine is typically produced from fermented grapes, not grain. Grain is used to produce beverages like beer and whiskey.

Question 6

The amount of alcohol from fermentation depends on the amount of sugar available for the yeast to consume.

Accepted Answer

The amount of alcohol produced during fermentation is directly related to the amount of sugar available for the yeast to consume, as yeast converts sugars into alcohol and carbon dioxide through the fermentation process.

Question 7

If there is limited sugar (or food for the yeast to consume), there will be a lot of alcohol expelled by the yeast.

Accepted Answer

Yeast produces alcohol through fermentation when it consumes sugar. If there is limited sugar available, there will be less alcohol produced because the yeast has less food to convert into alcohol.

Question 8

When does yeast stop consuming sugar?

Accepted Answer

The answer of When does yeast stop consuming sugar?...
