Lambic 6 months old, pellicle dropped!
 

Brewed a Lambic back in April, and I've left it be. I can't really see the pellicle because of scum left from the krausen in the carboy. I popped the airlock to have a look, and it looks like the pellicle is gone.

What's up?

I just took a taste, and there is certainly some brett character but not much sour. Contrast to my Flanders Red which is 9 months old, and plenty sour.

I used WL 655 straight up.

I've never used 655 but I've had beers fermented with 655 and they were definitely sour. I imagine you just need to give it more time.

Pellicles rise and fall in beers. You will probably see a new pellicle form in a few weeks with a different appearance than the last one. Nothing to worry about.

Just a FYI it took about 8 months before I noticed any tru sourness like you I only got a Brett like flavor at around 6 months.
