The step known as sparging, where the grain and water mixture is passed through a filter to add more water and ensure that all sugars have been extracted from the grains. It’s then boiled for around an hour to 90 minutes, during which time the hops are added, before being drained. Yeast is added to the liquid before it’s stored at a specific temperature and allowed to ferment. After fermenting, the mixture can rightly be called beer.The 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.As you can see, the beer recipe as well as the beer brew process is actually quite simple, but brewing the perfect beer can take years to master. It’s also important to remember the subtle distinctions between the beer brewing processes for each type of beer to create the unique flavours.
