Raspberry Berliner Weisse eBIAB 1

The last of 12 beers for the Skirmish in the Triad!!!  Whoa.  My brewing muscles are tired!  This is also a new beer I want to brew for NHC so I’m excited to see how it goes.  The base beer is the Berliner Weisse I’ve brewed many many times and now have a process I like and then just adding Oregon Fruit Raspberry Puree post primary fermentation.  So, my BW process is pretty standard kettle sour technique.  I mash, run off and then boil for 30 mins.  I then chill to 90F and pitch an Omega Lacto Blend.  This stuff is the bomb!  After all my different experiments this is the one I have settled on.  It sours FAST, is very clean and doesn’t drop the gravity at all.  After 24 hrs I’m usually down around 3.4 which is a good level by my tasted.  I then boil for 30 more minutes and follow a standard process from there.  For this beer I’ll wait till fermenation ends and then add 3 lbs of raspberry puree which should be about 0.75 lbs per gallon since it’s going into a 4 gallon batch.

I entered this in the skirmish and it didn’t do very well but the complaint was the fruit was too prominent.  i’m curious to see how this does in the next competition b/c I feel like this beer turned out awesome and i’ve gotten more compliments from friends on this beer than any other this year.  here are the skirmish comments:
