My Vermont Ale strain arrived at 84F. I don’t think it was warmer than that, if any, maybe a degree or two.
How bad is 84F for yeast?
Your yeast will be okay. Ale yeast will replicate up to the temperature of the human body.
Thank you Mark. For a 1.070 beer what is your shaken not stirred starter size?
1L into a 4L container or 1.25L into a 5L container. That should get you between ~200-250*109 cells.
