Brewed an all grain batch with a 1.057 OG. Wort cooled to 68/70. I rehydrated two safale 04 packets and pitched. One day later, vigorous fermentation (expected) but the temp shot up to 79!! Fermentation is known to warm up a bit but 9-11 degrees? It's in a cool basement that is a steady 66.
How concerned should I be? I imagine there may be a lot of off favors.
