Solution from VTT to prevent beer bottle explosions
Some contaminant yeasts make beer bottles and cans explode. Apart from being dangerous for consumers these ‘diastatic’ yeasts also cause loss of beer batches due to off-flavours, increased alcohol and over-carbonation in products. VTT scientists developed a genetic test for brewers to detect the strains that cause these problems. Diastatic yeasts are one of the most important and problematic contaminants in the brewing industry. The number of contaminations has increased during the past few years, particularly in smaller breweries. Diastatic yeasts cause problems in the brewing
