I am fermenting a beer with Safale 05. I used a starter and placed the carboy in a refrigerator, fired up my temp control device and let it go. Within a couple of days I had minor blow off.
Now, a week later I notice the temps in the frig are about 61F. I had set the unit to begin cooling so I would ferment on the cool side of the yeast specs around 68F.
The ambient temp in the garage where the frig is sitting is only about 61F.
The yeast is chugging along very well.
I do though have a question. Can I simply expect the beer to take longer to finish, but will not have any off flavors as a result of cool fermentation? I have always wanted to be on the cool rather than the warm side of my ferments, but is this too cool?
