Beer Flashcards
When was the Bavarian Purity Law codified? Which 3 ingredients did is authorise for beer production?
1516
Barley, Hops, and Water
Outline the process of malting to make beer
Barley (or the cereal grain of choice) is steeped in water to promote germination - the amylase enzyme is produced - amylase converts the starchy carbohydrates of the grain into fermentable sugars maltose and dextrin.
The “green malt” is then roasted to suppress further growth (the level of roasting will dictate the style of beer)
What is grist in beer making?
Is the cracked or ground malted grain
Grist + hot water = ?
Mash tun
What does the mashing process do in beer making? How long does it generally take?
It converts and extracts sugars from the malt
1-2hrs
In beer making what is the solution called after fermentable sugars have been extracted from the malt and before fermentation begins?
Wort
What is sparging?
Rinsing the grains after mashing and filtration to extract additional sugar and flavour. This can sometimes contribute to bitterness in the finished brew.
When are hops usually added to beer?
Usually they are added to the boiling wart before fermentation and then again in a hopback chamber prior to chilling
At what point in fermentation does a lager differ from an ale?
- After the hopping and during the cooling of the wort. Lager wort is cooled to a lower temperature.
- Yeast fermentation. Ales take a top-fermenting yeast (saccharomyces cerevisiae) and Lagers take a bottom fermenting yeast (saccharomyces pastorianus)
Does Ale or Lager yeast ferment more quickly and at a hotter temperature?
Ale yeast. Top-fermenting.
What are bottle-conditioned beers?
Unfiltered beer that undergoes partial fermentation in bottle
What is a lambic beer? Where is it from?
Beer that is spontaneously fermented in open-top containers with native wild yeasts such as Brettanomyces bruxellensis and Brettanomyces lambicus
Belgium
How are lambics generally treated post fermentation
Aged in cask for often up to 3yrs and blended before bottling
What style of beer is often referred to as Brussels Champagne?
Gueuze
How is Gueze made?
One year old lambics (which still have fermentable sugars) are mixed with beers that have aged 2 to 3 years and re-fermented in bottle giving the beer it’s sparkle
What is kriek?
A fruit lambic made with morello cherries
What is the name for a fruit lambic made with raspberries?
Framboise
What style is beer is Cantillon?
Gueuze
Name an American brewery that makes a lambic-style beer
Allagash
What is special about the hops used for a lambic beer?
They are aged, so they don’t impart a strong flavour
What is a coolship?
A big shallow vessel used to cool the wort for lambic beer that helps expose it to wild yeasts for fermentation
What valley around Brussels is known as the home of lambic beer?
Zenne Valley
Name 3 producers of lambic beer in Belgium
3 (Drie) Fonteinen
Cantillon
Gooik
