Hey, first time poster, recently signed up for BF. I'm going to be doing a stout this weekend and I have a friend who works at a local brewery, so I thought it would be fun to get some yeast from them. So I boiled a mason jar to sanitize it and took it in today to get it filled. When I got home, I decided that since I'd be using it on Saturday and not today, I didn't want it sealed for 3 days and exploding on me, so I cracked it open and was going to put it in a ziplock before putting it in the fridge. Well they filled it it nice and full because it came gushing out when I opened it. So here's my concern...the jar was sterilized but when I took it to and from the brewery, obviously the exterior no longer is. I don't plan to use any of the yeast that dripped out but should I be concerned at all with what's still in the jar? The jar is in a ziploc so I feel ok about that at least.
