Brewing the Artisanal Blonde Beer ZerB 100 % Basque
The process for obtaining this quality brew develops in 3 phases:
A broth resulting from boiling the malts (roasted cereal) in water, converting the starches into sugars which are subsequently transformed into alcohol prior to the fermentation step. At this stage the hops are added which provide the characteristic bitterness of the beer.
After adding the yeast, the broth is fermented at 17 º C.
The sugars are transformed into alcohol and the broth density is measured to make sure that 5.3% specific to ZerB is present.
During 4-5 weeks, the beer maturesin tanks in which the yeast generatesgas, unlike industrial beer to which carbon dioxide is artificiallyadded, then bottled and labelled.
This beer is not pasteurizednor filteredso that its organoleptic and nutritional properties are kept. This means it may contain sediments therefore vertical storage is recommended.
Kölsch style beers. After the elaboration of low fermentation beers spread throughoutGermany, the city of Köln continued to use the high fermentationstyle and they began using cold maturation and paler malts thus obtaining golden beers. They are usually very fruity, soft and pale coloured.
