Default I screwed up the temp with yeast - what to do?

I think I was so worn out when I got home that I misread the directions on my extract kit from Austin. The directions state that I should refrigerate my yeast until brew day and then to take the yeast out up to 24 hours before use and let sit at 72-78 degrees.

I thought it read to set it out for "at least" 24 hours before use. Being that I am planning on brewing this Saturday I went ahead and set it on top of my fridge and it has been sitting there for 5 hours now.

What should I do - put it back in the fridge or leave it out?

You should stop worrying. It won't make any difference. No point in cooling it down today, just to warm it up tomorrow.

You can go ahead and refridgerate it. You could also make a starter.

Don't worry. The recommendation for refrigeration is to retain good yeast viability after a long period of storage; in the case of dried yeast, that could be a couple of years. A few days at room temperature will not make any difference.

I think the idea of removing it from the fridge is bring it up to pitching temp.

Remember, these kits can sit for months on shelves, so a few days will not matter.

I assume he is talking about dried yeast - You do not want to make a starter with dried yeast. The yeast has all the nutrients it needs and making a starter will deplete he nutrients. Also, the cell count with dried yeast is a lot more than with a package of liquid yeast.

Does liquid make my situation different or will 48hrs be fine at room temp?

Thanks

No difference with leaving it out for a couple of days, but I agree with Stormrider that you should make a starter. While pitching the vial should ferment your beer (if it's high gravity you could have problems), making a starter will get the ferment off quicker, and put less stress on the yeast.

As Calder said, the best thing to do would be to make a starter.
A few days at room temperature won't make any noticeable difference, but you need to refrigerate for long term storage (more than a week or so).
