Well its been a while since I have updated the sour beer project, but these things do take time. The pH has been steadily dropping its around 3.3pH at the moment. My goal is 3.0pH.
It has formed a rather attractive pellicle as you can see it the photos. The smell is there as well, but still it's going to be a while before its ready to bottle.... then it will take some more time to naturally carbonate. But I am patient.
