How long will yeast obtained from a brewery keep?

[dsuarez]

So I am itching to do a brew, but have a very erratic work schedule. I am planning on filling up a mason jar with some yeast from a local brewery. I have no idea when I will be able to brew next but hopefully sometime this week. no time for starters. how long will this mason jar last in the fridge/freezer without having to do a starter?

is fridge or freezer better?

don't freeze it...without proper care, the cell walls will burst

unless you know that they loaded it up w/ nutrients, etc... i'd say keep it in the fridge for no more than a week if you're not going to build a starter
just take it out and leave it at room temp for ~ 6 hrs before pitching
