FST 003V Beer & Brewing
In an open fermenter, the yeast cells are under less hydrostatic pressure which is the
reason these yeast are said to do what for the beer? - answer Produce more fruity
esters
Why is it beneficial to use a wet mill as opposed to a dry mill? - answer Wet mills
prevent the husk from becoming damaged
What is significant about raising the temperature of the mash to 65°C? - answer The
starch melts at this temperature in a process called gelatinization, converting it to a form
that enzymes can use.
What method is used after fermentation to remove the diacetyl that is produced during
fermentation and is responsible for the popcorn and butterscotch aromas? -
answerLeaving the yeast on the liquid to take away the compound
Darcy's Law helps us balance which of these to maximize the rate of flow during the
brewing process? (select 2) - answer Pressure
Cross sectional area
Why are fermentation vessels surrounded by cooling jackets? - answerTo counteract
the metabolic heat produced by the yeast
The fermentable liquid that eventually becomes beer is referred to as - answerWort
What is used as a filtering aid to clarify beer? - answerDiatomaceous earth
What is the relationship between sparging in the lauter tun and specific gravity? -
answerThe more you sparge the lower the specific gravity
How long is the wort typically boiling in the kettle? - answer1 hour
Match the scientist with his contribution to brewing science:
1) Pasteur
2) Emil Christian Hansen
3) Sorensen
4) Gosset - answer1) confirmed that yeast caused alcoholic fermentation
2) isolated pure yeast
3) described the concept of pH
4) developed statistics in barley breeding and furnished the student t-test
Which is true of lager-style beer? - answerinvolves bottom fermentation
, What was the significance of St. Paul's Cathedral? - answerThe monks were brewing
thousands of barrels of beer
Pliny the Elder discovered - answercerevisiae in Gaul and cera in Spain
What was the significance of the 1800 Code of Hammurabi? - answerRegulation of beer
has deep historical roots
What were the three staples of the ancient Egyptian diet? - answerBeer
Onions
Bread
Gruit is: - answerA blend of herbs and spices used to flavor beer
In the early Middle Ages, ___________ was the drink of choice because it was safer
than water. - answerAle
The Revolutionary War resulted decreased beer imports from England and politicians
encouraging people to go into brewing on a commercial scale. - answerTrue
A brewster is a - answerFemale brewer
Which materials are broken down by the enzymes during the modification of barley? -
answerCell walls and proteins
What is happening when the enzymes are produced? - answerThe kernel germinates
Water is the trigger for the embryo to begin the enzymatic breakdown of the starchy
endosperm. - answerTrue
Water makes the starchy endosperm amenable to digestion by enzymes.
Can feed barley be malted? - answerYes
Six-row barley malt typically contains more enzymes than two-row barley malt. -
answerTrue
During a typical malting process, the highest moisture content the barley kernel
experiences is roughly: - answer44%
Enzymes are synthesized in the: - answeraleurone
Why do brewers typically prefer 2-row barley instead of 6-row? - answerThe grain is
larger and produces more starch
