I just caught wind of this report from Charlie Papazian. Severe thunderstorms and hail ravaged Europe earlier this week, and the Hallertauer area, famous for its Hallertauer Hallertau hops, was severely damaged. For lovers of many traditional German beer styles, this is not good news.
One [Brewers Association] member from the Netherlands reports, “Staff of Bayerische Staatsbrauerei Weihenstephaner [where the German brewing school resides], who live throughout the area, have all reported the complete destruction of hop fields in the region.” Other reports indicate that the damage was local in some areas and effected about only 25% of the region.
Also effected are several Sam Adams beers, including their flagship Boston Lager. According to Papazian’s article, it can take up to two years for a newly planted hop vine to yield a full harvest, so production may be effected for a couple years. Other Hallertau growing regions around the world may be able to fill some of the demand, but while their bitterness is similar, varieties grown elsewhere tend to have a floral note that Hallertauer-grown hops lack.
Let’s hope that the damage is not too widespread, especially if you homebrew with Hallertauer-grown hops. I have to imagine that Jim Koch would be able to get his hands on hops before your local homebrew shop would.
