Being a liquid yeast,you'll have to make a starter for it anyway. But next time,always put your yeasts in the fridge. I keep mine in the butter cubby on the fridge door. LME's also go in the fridge. Hop packets in a zip lock bag in the freezer. Things stay fresher that way. And be careful openning the yeast vial. They have co2 pressure in them from the yeast like a 2L soda bottle. Just crack the lid a little to release some of the pressure. When it looks like it's going to spew,close it. Repeat till the pressure is gone,then open. You won't loose a ton of yeast this way.
