My first brew is currently fermenting on its 6th day. I just checked the temperature and it was quite a bit lower than what I initially thought. The temperature in the room is 12'C (54'F) and the brew had almost the same temperature. I just did a test with my hydrometer and it measured to 1020, which translates to around 1019 with temperature adjustments.
I have used the White Labs WLP001 California Ale Yeast.
Is this brew spilled or can I do anything to save it?
