Hello.
I'm beer geek from Poland and I'd like to share a link to youtube video of the most watched craft beer blogger from my country, Tomek Kopyra (he's judging at events all over the world, including Denver). He has another channel exclusively for english reviews and recently he had an opportunity to review original 23-years old grodziskie beer (Grätzer). Check if it's not spoiled:
Here's quote from wikipedia page of Grodziskie:
Grodziskie (Grätzer, Grodzisz) is a style of beer from Poland that is made primarily or entirely from wheat that has been malted and then kiln-dried with oak wood, giving the grain a smokey oak character. The beer looks and acts like Champagne, with a clear, pale yellow to golden color and high carbonation levels, and has low to medium levels of hop bitterness.
I hope more people all around the world will come to this channel so Tomek will post more reviews in english as Poland's craft beer scene has MUCH to offer every new day!
There's review of 30-years old Żywiec Porter too!
Cheers!
