The first, called low fermentationbeers, dates back to 1840, and is more commonly known as Pils or lager. Its light, fresh taste make it a very popular drink, representing over 90 % of all world beer production.
More closely linked to Belgian tradition, high fermentation beers lso known as tasting beers usually have a higher alcohol content than « Pils ». Some examples are amber beers, "Trappistes", Strong Pils and Regional Beers. With less alcohol, seasonal beers and "Blanches" end the list of this second category.
Lastly, the third category with spontaneous fermentation is produced in Brussels and surrounding areas.
