Beer Flashcards
what are the 4 base ingredients of beer?
- water
- cereal / grain + malt
- yeast
- hops
what are the 2 basic categories of beer?
- ales
2. lagers
Ales use __-fermenting yeasts.
Lagers use __-fermenting yeasts.
- ales = top fermenting yeasts
- lagers = bottom fermenting Yeasts
Ales ferment at ___er temperatures.
Lagers ferment at ___er temperatures.
- ales ferment at warmer temps
- lagers ferment at cooler temps
how do ales and lagers differ in aromas + flavours?
- Ales = more fruity
- lagers = crisp + clean
give an example of a German ale
Hefeweizen
give 3 examples of a British Ale
- Pale Ale
- India Pale Ale (IPA)
- Porter
give an example of an Irish Ale
stout
give 2 examples of Belgian Ales
- Lambic (which has spontaneous fermentation)
2. Wit or White Bier
Give an example of a Czech Lager
Pilsner
Give 3 examples of a German Lager
- Bock
- Doppelbock
- Oktoberfest
what percent of beer is water?
85-90%
the chemical makeup of water can determine what …. of beer is brewed
style
which cereal grain is most used to brew beer because of its high quality?
Barley
what other cereal grains can be used to brew beer?
- oats
- rice
- wheat
- corn
- rye
In order for fermentation to happen, what does a brewer have to do to the cereal grain?
Germinate the cereal grain, to turn its starches into fermentable sugars – because yeasts eat sugar, not starch.
what is malt?
cereal or grain that’s been germinated
what is the next step for malt after it’s been germinated?
it’s dried in a kiln
the style of beer that’s ultimately produced – in regards to color, flavor, and aroma – depends on what?
- temperature at which malt is kilned
- how long the malt is kilned
what determines if a beer is an ale or a lager?
the yeast strain
in beer production, what ferments the malt sugars into alcohol?
- mold
- botrytis
- yeast
besides fermenting malt sugars into alcohol, what other role do yeast play in beer production?
they contribute characteristic aromas and flavors to the beer
what are hops
hops are flowers of the hop plant that are used in beer production
what are the roles of hops in beer production?
- hier resin, when boiled in the fermentation process, contributes bitterness to beer which helps counterbalance the weet maltiness in beer;
- acts as a preservative
- lend flavours + aromas
