What does conditioning beer do

Acetaldehyde is an aldehyde that has a pronounced green apple smell and taste. It is an intermediate compound in the production of ethanol.

The yeast reduce these compounds during the later stages of fermentation. The yeast also produce an array of fusel alcohols during primary fermentation in addition to ethanol.

Fusels are higher molecular weight alcohols that often give harsh solvent-like tastes to beer. If your beer has moved about then let it settle for a while and then open and pour gently into a glass.

Bottle conditioned beer can be served chilled or warm, depending on your preference. Many beer aficionados prefer pale and golden ales in a chilled glass or after 20 minutes in the fridge. Darker ales are often best at that optimum storage temperature of around 50 F.

One very important part of this involves the brewers manipulating the environment in the tank to encourage the yeast to reabsorb or convert some of the negative compounds in the beer, primarily diacetyl.

Diacetyl is a buttery compound which is produced during all fermentations. Also during the maturation stage, beer can be dry-hopped, and we expect some of the residual yeast in the tank to gradually be dropping through the beer to leave it looking clearer.

Most great lagers will spend at least two weeks and up to six weeks cold conditioning giving a total production time of four to eight weeks , during which time the beer is getting gradually cleaner, clearer, smoother and crisper.

Time mellows and sharpens the flavour of great lagers. So what if the beers were lagered for another month, will it continue to get better?
