I just pitched 3L of yeast into my Octoberfest Lager last night. I pitched it with the wort at about 56 degrees. I added a couple of frozen bottles of water last night and the temp was 55 degrees when I woke up this morning. Once the fermentation really gets going will I need to add more than 2 bottles to keep the right temp? I have no idea how much heat the fermentation process throws off. This is my first lager and I don’t want to screw it up:). The beer did have a 1 inch krausen already so fermentation is already going.
The swamp cooler is sitting on my concrete basement floor. The ambient room temp runs from 58-64 degrees during the day.
