Default Mold on top of yeast slurry jar

Hey guys,

Went to make a starter from saved slurry this evening and there was a dime sized chunk of what looked like white mold floating on the surface of the liquid in the mason jar. I poured it out and went ahead with making the starter , but should I use it?

Get new yeast if you think it was mold. No reason to risk an entire batch for a few dollars in new yeast.

Just boil it to kill any possibilities of infection.

Of course you could also bake it in the oven for about 2 hours and make your own dried yeast.

That'll work, right? Right?

I guess I thought that since the infection was separated from the yeast by beer, I'd be ok... Everything smelled fine.

Oh well, I have a back up packet of dry yeast to use for tonight.

I've been having issues with washing yeast lately. I follow the sticky in the forum, and usually 2 out of the 4 mason jars I end up with usually has some mold on the surface of the beer when I go to use the yeast. I've never had an infected beer in 6 years of brewing, and I always thought I was practicing good sanitation.

I would give up washing yeast, and simply store and repitch the yeast slurry that can be found in the bottom of your fermenter, IMHO less chance of infection and a hell of a lot easier!
