Abstract:
Aging beers In barrels is an increasingly popular technique in the craft sector and are increasingly those that spend part of their production to this type of aging that gives complexity and nuance.The objective of this work is to study the use of barrels in the Segarreta craft brewery for the production of acidic beers. The work is based on a physical, chemical and microbiological study with different culture media to study the population of beer microorganisms with a first controlled fermentation in stainless steel fermenters and a subsequent acidification in barrels. In parallel, the evolution of beers with spontaneous fermentation has been studied. The aging of samples of Sour Ale de Raspberry beers has also been studied through sensory parameters supported by physical-chemical analyzes.
