I found a post on my issue and it is sort of disheartening, seeing as how I'm looking at my yeast starter slowly spew out yeast product. I had made a nice little starter with my new 2L flask last week but had something come up so I didn't brew. I had it in the fridge all week and decided to give it a little bump so I decanted the fluid and poured in a smaller 1quart wort starter so I can brew again on Sunday. Came down this morning to an overflow, and it's been slowly going all day long.
Is there something I can do to keep it from bubbling good yeast out of my flask?!? The stir bar is off because any movement seems to set this thing off.
