How does beer go stale?
Time. The compounds that keep beer tasting fresh start to break down and stale tasting compounds arise.
tastes papery or like cardboard. sometimes start to smell sweat like honey
Why are warm temperatures bad for beer?
Warm temperatures speed up the natural staling process. the warmer a beer is kept the less fresh it will be. It should be stored and delivered while staying chilled
Why is oxygen bad for beer after fermentation?
Oxygen is good to add to the wort because it helps the yeast but once fermentation is done and the yeast is removed we do not want oxygen in the beer.
oxygen leads to staleness
Why is light bad for beer?
natural and artificial light can lead to beer becoming stale.
Light reacts with the bitterness compounds of the hops and creates an onion skunk-like aroma (light struck).
Thats why cans are good. Brown bottles too. green and clear bottles are in the most danger of lightstruck happening.
What are the 4 factors that make beer go stale?
1) temperature
2) light
3) time
4) oxygen
What is orthonasal and retronal?
Orthonasal: sniffing
Retronasal: back of the nose (perception of odors in the oral cavity)
Why does beer foam remain of the top of beer?
Proteins and hop compounds form a layer that cling together around carbon dioxide bubbles
What does “Diacetyle” taste like?
Butterscotch. Not wanted in light lagers but is liked in Czech pilsners
What in beer is good for you?
1) low in sugar: no simple sugar but a small amount of complex cards that get broken down. 2-5g/100ml compared to pop which is 5-10g/100ml.
2) low in fat
3) low in sodium
4) good source of silicon: comes from the cereals. good for bone formation. 20mg/1litre compared to water which has 14mg/1litre.
5) high amounts of mineral phosphorous: good for digestion and bone formation. also has B vitamins
Recomended maximum beer consumption for the UK, US, Autralia and Canada?
UK: 14 units per week = 6 pints/3.4 litres
US: 14 bottles = 4.97 litres
Australia: 10 drinks = 2.85 litres
Canada: 15 drinks = 4.28 litres
Tell me some shit about kegs?
Made out of stainless steal (doesn’t corrode or lead to a metallic flavour)
outside of keg has ridges called “rolling rings” to help move the kegs around safer and more easily
Cleaned upside down.
Pre pressurized with CO2. beer gets filled in from the bottom (top of keg but its upside down) and the CO2 gets pushed up and then back down till it gets released from the “spear” out the bottom (top) of the keg.
“Keg spear” where beer comes in and out of the keg
“Dispense head” is attached to the valve at the top of the spear
Tell me some shit about casks?
Originally made of wood but mostly stainless steal now. Also have rolling rings. Mostly used in the UK.
Casks have 2 inlets: 1) Port of the side where it is filled is called the “SHIVE BOSS” and is plugged with bung called a “shive” a “spile” is added later on.
2) Port of the end is where the beer is emptied. its called the “keystone boss” and is closed with a bung called the “keystone”. A tap is driven into the keystone when emptying beer.
What is the cap on a beer bottle called?
Crown
Tell me some shit about beer cans?
First made 100 years ago but were like cans of beans and were messy to drink from.
Made out of aluminum or stainless steel. Have a body, lid or end. A pull tab, rivet pin and opening panel.
Can be sizes from 150ml to 750ml.
