Yeast: the 'fermenter' of beer
Yeast is a living organism that is very important for beer’s taste by turning sugar into alcohol.
Brewers often keep their own yeast cultures safely protected to guarantee a consistent taste. We have more than 1200 yeast strains in our portfolio that are protected. Not all of them are currently used, which gives our brewers lots of room to innovate and create new beers.
Yeast gives beer different aromas, for example banana, rose, apple, aniseed, almonds, cloves and pepper, just to name a few.
There are two basic types of brewer’s yeast – Ale and Lager – with different general taste qualities. Ale yeast delivers a more intense flavour while lager yeast results in cleaner and crisper qualities.
