In recent years, there has been much ado about diastaticus and hop creep. One is driven by certain strains of yeast and the other is driven by hops, but in both cases, unintended fermentation continues after the beer has been packaged. In mild cases, it results in off flavors in beer, but in extreme cases, cans rupture or bottles explode. These are important issues in beer quality that affect not just brewers, but consumers as well.
On this episode of the All About Beer Podcast, Don Tse and Em Sauter talk with a fermentation expert about diastaticus and a brewer about hop creep. They explain the issues, why consumers should be aware of them and what brewers can do to ensure their beer is both delicious and safe.
