Hot yeast.

[mximus11]

So, I got my beer kit from AHS and it had speed over the weekend. The liquid yeast sat in hot warehouse all weekend. when I finally got it out of the box it had to be between 80-90°. I put it in the refrigerator right away. So, the obvious question is... Is my yeast going to be ok? Thank you

Make a starter and you will know if it is viable and to build up some yeast that died in the heat.
Good luck.
