I brewed a berlinerwiese about 6 weeks ago and it is still sitting in primary. I used the While Labs wlp 630 yeast. I have pretty much stopped doing secondaries after reading some of the posts here and have had much success. I have it in a "borrowed" 5 gallon plastic water jug. It is one of the new kind that is a HPDE 2. I have a towel over it to protect it from light. I was planning on aging this for about 5 months so it gets nice and sour (the aging is the secret to the sour from what I have been told). Is 5 months too long on the original yeast cake? Since there is Lacto somethingoranother as well as regular yeast does that make me want to do a secondary?
