It's good to be progressive, but don't shun the good things about tradition. Think about this while enjoying a glass of Liefmans Oud Bruin. The typical taste of the beer that originated in 1679 comes from special malts fermented in open tubs that mature for 4 to 8 months.
The matured beer is mixed with younger brewer's yeast, creating a brew with a more balanced, consistent taste. Older beers are richer in aromas, in a blend with young beer they become fresher and sweeter. Liefmans Oud Bruin smells and tastes of grilled malt and caramel, surrounded by fruits and spices. Sour and sweet are perfectly balanced. A small miracle!
