Beers are broken into two basic types, of which sub-types are created. What are the two basic types of beer?
Correct Answer
B. Ales and Lagers
Explanation
Ales and Lagers are the two basic types of beer. Ales are brewed with top-fermenting yeast at warmer temperatures, resulting in a more robust and fruity flavor profile. Lagers, on the other hand, are brewed with bottom-fermenting yeast at cooler temperatures, which leads to a cleaner and crisper taste. These two types of beer have distinct characteristics and are differentiated by the type of yeast used and the fermentation process.

3.
The color of a beer is measured using which of the following?
Correct Answer(s)
B. SRM - Standard Reference Model

Explanation
SM = Single Malt, "and" "SH" = Single Hops
6.
"Noble" hops are identified as hops which are:
Correct Answer
C. Any of four hops, low in bitterness and high in aroma
Explanation

7.
One way (there are many) to sour a beer during the mashing step (sometimes called Turbid Mashing), requires what to be introduced into the mash?
Correct Answer
E. All of the above
Explanation
Some sort of foreign "funk" must be added to give those off flavors which are required for soured beers.
8.
Beer yeasts are generally set into two major categories. These two categories are:
Correct Answer
C. Top fermenting and bottom fermenting yeast
Explanation
Beer yeasts are generally categorized into two major types based on their fermentation behavior: top fermenting and bottom fermenting yeast. Top fermenting yeast, also known as ale yeast, ferments at warmer temperatures and rises to the top of the fermentation vessel. It is used to produce ales and other top-fermented beers. On the other hand, bottom fermenting yeast, also known as lager yeast, ferments at cooler temperatures and settles at the bottom of the fermentation vessel. It is used to produce lagers and other bottom-fermented beers. Therefore, the correct answer is top fermenting and bottom fermenting yeast.
9.
A belgian style beer is named "belgian" due to which of the following:
Correct Answer
B. The type of yeast which is used to ferment the beer
10.
In order to darken a beer during brewing, which of the following methods could be employed?
Correct Answer
E. All of the above
Explanation
Any of these will darken the finished beer. Base grains will have the least effect but eventually will darken it.
11.
A "phenolic" taste in a finished beer can be identified with what type of taste when drinking the beer?
Correct Answer
A. Medicinal
Explanation
Phenol tastes are medicinal - sometimes called a "band-aid" taste.
12.
Yeast can survive and continue to ferment in environments as high as 15% alcohol by volume.
Correct Answer
A. True
Explanation
Some yeasts can survive in 20% abv or higher.
13.
Beers which are made out of grains other than barley, oats, rye or wheat are called _______ beers.
Correct Answer
C. Gluten Free
Explanation
Beers which are made out of grains other than barley, oats, rye or wheat are called gluten-free beers. This means that these beers do not contain gluten, which is a protein found in these grains and can cause adverse reactions in individuals with gluten intolerance or celiac disease. Therefore, the correct answer is "Gluten Free".
14.
The boiling of grains during the mash step is called a __________ step.
Correct Answer
D. Deconcoction
Explanation
The correct answer is "Deconcoction" because during the mash step, the boiling of grains is a process known as decoction. Decoction involves removing a portion of the mash, boiling it, and then returning it to the main mash to raise the temperature. This technique is used to increase the temperature of the mash and extract more fermentable sugars from the grains.
15.
Commercial beer production volumes are measured in barrels. A full barrel of beer has 31 gallons of beer in it. How many 12 ounce bottles are in 1 full barrel of beer?
Correct Answer
C. 330
Explanation
1 gallon = 128 ounces
Therefore, 31 gallons = 31 * 128 ounces
31 gallons×128 ounces/gallon=3968 ounces
Next, we divide the total number of ounces by the size of each bottle (12 ounces):
3968 ounces÷12 ounces/bottle=330.67 bottles
Since we can't have a fraction of a bottle, we round to the nearest whole number:
330
16.
Beers that are high in alcohol content which are made from fruit are called "Barley Wines"
Correct Answer
B. False
Explanation
It's in the name: BARLEY -- so it's false.
17.
Dry hopping is the process where hops are added to the secondary fermentation, in order to add hop aroma to the finished beer. Adding hops to a mash is done in order to:
Correct Answer
B. Add more bitterness to the finished beer
Explanation
Adding hops to a mash is done in order to add more bitterness to the finished beer. Hops contain alpha acids that contribute to the bitterness of the beer. When hops are added during the mashing process, these alpha acids are released and dissolved into the wort, resulting in a more bitter taste in the final product.
18.
Which of the following is NOT fermentable by beer yeast?
Correct Answer
E. None of the above
Explanation
Beer yeast is capable of fermenting various sugars to produce alcohol and carbon dioxide. Maltose, dextrose, and sucrose are all fermentable sugars commonly found in beer. Therefore, the correct answer is "None of the above," indicating that all of the listed sugars are fermentable by beer yeast.
19.
The name of the foam on the top of fermenting beer is called:
Correct Answer
A. Krausen
Explanation
Krausen refers to the foam that forms on top of fermenting beer. It is created as a result of the vigorous fermentation process, where yeast consumes sugars and produces carbon dioxide and alcohol. The foam consists of proteins, yeast, and other fermentation byproducts. This layer of foam acts as a protective barrier, preventing oxygen from entering the beer and allowing the yeast to work efficiently. Therefore, the correct answer is Krausen.
