How long should Beer ferment?
October 26th, 2009 . by adminThe beer is left to ferment for a different length of time depending on the type of beer that is required, usually around 21 days for ales and 35 days for lagers. The yeast used is also different depending on the type of Beer, with ales requiring top fermenting yeast and lager having yeast that settles to the bottom of the beer right away. The temperature at which the beer is allowed to ferment is also important, with ales requiring a higher temperature than lagers. The hops can be added to the beer at different times during the boiling stage depending on the level of bitterness and the aroma required, and for speciality beers the extra flavours are added at the end.
