Ok, so I am still using my Mr. Beer setup since I am still very much a novice at home brewing, and I have ordered some supplies from their website. I am trying to make a stout so I ordered their liquid stout yeast, which clearly says on the package to keep at a temp between I think 36- 40 degrees. It was shipped via UPS in a normal box and wrapped in bubble wrap. Is it still good to use since it has not been refrigerated the whole time? I put it in the fridge as soon as I opened the box so I am hoping that it will still be ok.
