did I just cook my starter?
« on: June 19, 2014, 08:39:36 AM »
Had an old smack pack of Wyast Urquell yeast, and after about a week it swelled. So i made .5l of 1.020 wort and as i pitched, i realized i had not cooled it very much. I put it on a stir plate; the pack was at about 76, but pitched into 92. Think I killed it?

Nope. 30°C/86°F is the standard temperature for yeast propagation. You don't have to worry about doing harm until you get to around 110°F, depending on the strain.
Beer is like porn. You can buy it, but it's more fun to make your own.
