Beers Flashcards
Ales vs Lagers fermentation
Ales
Top fermenting, shorter fermentation at higher temps
Less roasted malts
Lagers
Bottom fermenting, longer fermentation at cooler temps
Darker the roast on malts, deeper the flavor
Grist
Roasted barley or grain after germination
Ground by mill
Amylase
Enzyme that changes starches into maltrose and dextrin sugars
Turns grains into “green malt”
Green malt
Germinated grains before roasting process, before steeping into wort
Roasting process
Roasting germinated grains after a two day germination to dry out and develop sugars into desired beer style roast
Sparging
Rinsing separated wort grains with fresh water - can lead to more unwanted final bitterness
Wort boiling
Stabilizes and sterilizes brew, deepens color, and evaporates excess water
Hops influence
Flavor and bitterness
Longer boiled - lose flavor, only bitter
Citrus, floral flavors if added and aromas kept
Ale fermentation
Add Sacchromyces cerevisiae yeasts
Higher temp, lasts less than a week
Fruity and richly flavored beer
Lager fermentation
Add saccharomyces pastorianus yeasts
Cooled to lower temps
Lasts longer
Delicate and cleaner beers
Bottle conditioning
Fermentation finished in bottle
Cask ales sold by draught
Unpasteurized
