In olden days, people thought beer happened because of many strange beliefs. It was only recently some clever guy with a microscope realised that those lively little microbes there are eating sugar, farting carbon dioxide gas and peeing alcohol. Not angels, demons or spirits, just plain microscopic little creatures eating and breeding and living their life, and then we enjoy their excrement. Nice, eh? Granted, it is the excrement of a very particular species of microbug. This is very important: The excrement of whatsisname cervensis tastes like beer, whereas just about every other form of yeast, fungus or microbe gives of waste that does not taste like beer. As a matter of fact, the excrement of just about every single organism other than C.Cervensis tastes like…poop?
This is why it is utterly, unforgivingly, important to be sterile in your dealings with your beer. Very many commercial brewers have difficulty getting this right, that’s why their beers give you hangovers and headaches before you even go to sleep. How many beer drinkers won’t swear high and low that Charley’s Palace Lager tastes better in cans than dumpies, whereas Red Sticker Beer is best enjoyed in quart bottles? Usually, the cans and the bottles are from different locations, each with its own set of infections, and therefor even a multibillion-dollar company cannot make the same brand taste the same every time. Imagine how difficult it is going to be for you in your kitchen. TAKE CARE.
