Rehydrating Hot

[MacGruber]

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.

Nah you are fine. Most places suggest warm water.

Warmer temperatures are usually what manufacturers recommend. Remember to cool your yeast to with in a couple degrees of your wort before you pitch. Don't want them going into thermal shock.

Man, I really hope the OP hasn't been sitting around with a bowl of hydrated yeast waiting for a reply...

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.
