As I have been unable to brew for a while, I have been using other outlets for my brewing itch. One such outlet has been collecting a bunch of dregs from beers.
I have been storing them in 100ml sterile plastic cups.
Anyways. Everytime I checked in the Saison Rue dregs, the cup was definitely expanded from gas. After opening and closing it several times I decided to leave the cap loose for a bit. Mind you this is in the fridge. Just checked on it, and well, it is fermenting... There is a small pellicle starting to form in the top.
Can Brett ferment at such cold temps?
That was a long ass buildup to a simple question.
