I was just wondering if rehydrating dry yeast with water warmer than 80 degrees would produce off flavors in the final product? I rehydrated two packets of US-05 and it may have been warmer than 80. I forgot to take the temp of the water before adding the yeast. It was warm to the touch, but around body temp. Thoughts?

Necro reply: Rehydration temp recommendation is between 95 and 105 F. Found that information in other threads about rehydrating yeast on here.

Fermentis recommends rehydrating at 77° to 84°F.

Danstar recommends 86° to 95°F. Bread yeast is proofed at 110° to 115°F.
If it felt about body temperature you are most likely okay. Damage may not begin until rehydration temperatures begin exceeding 120°F.
