So I pitched my yeast (WLP013 London Ale) around 64 degrees in my basement (ambient is low 60’s) put in my swamp cooler with a wet towel covering it. About 8 hours later I saw the start of krausen forming but the temp had decreased to 60 and appeared to be dropping. So I decided to bring the beer upstairs where we keep the thermostat at 69. Before I went to bed it was still sitting at a steady 60 degrees so I didn’t put the fan on it when I went to bed.
I woke up this morning, the krausen is maybe only an inch thick and the temp is down to 58! So I immediately pulled it out of the water but i don’t really have any source of heat for it other than ambient temps. I left for work with it out of the swamp cooler in hopes that temps would rise to mid 60’s.
My first beer, i struggled with keeping the temps down, now, on my fifth, I’m fighting the battle of keeping them up. I won’t be home for another 12 hours so I hope fermentation doesn’t kick into high gear and the temps fly up to the mid 70’s. The yeast will surely be mad at me if that happens.
