Getting Sour

For the last several months, I’ve really been getting into the sour beers. The first sour I brewed was a Berliner Weisse that I brewed over the summer. With the Berliner Weisse under my belt, it was time for something a little more advanced, a pseudo Lambic (or pLambic). I plan to leave it alone in my fermenting room for 9 to 12 months. After that,
I plan to do three things:
1. bottle a few to drink as straight lambic
2. add fruit to two or three gallons for a fruit lambic
3. bulk age the remainder with the intent of blending with lambic made in future years to make gueuze

I’ll decide the type of fruit after I taste the Lambic and determine what will complement it. I’ll now have to commit to making a batch of Lambic each fall – it’s a tough life.
