Default I should have used a blowoff tube...

I think I'll be alright, but this morning I woke up to a gunky mess coming out of my yeast starter. The airlock (wish I used a blowoff tube) was filled with yeast/wort & quite a bit of yeast/wort had spilled out onto the table.

I'm using a 2L erlenmeyer flask & figured I'd have plenty of room since I was only doing a 1.2L starter on a stir plate. I had just stepped up from a 1.2L starter that I cold crashed & decanted, but it appears that I underestimated the power of the yeast.

After encountering my morning suprise, I popped off the airlock, rinsed & cleaned, sanitized, refilled with vodka, & replaced it. I'm hoping that everything will be ok.

How exciting! My first batch & I've already decided that even for my yeast starters, I will use a blowoff tube from now on.

Never underestimate the power of the schwartz...er yeast!
Tomorrow is brew day, just hoping I didn't infect my starter...

Better yet, cover the flask with a napkin fastened with a rubber band.

+1 on this. I think I've read on here you want your starter to be able to breathe to help the yeast do their thing. I don't use any airlock/tube with my starters and I've never had any issues.

This is interesting, because I was thinking the same thing in regards to allowing oxygen to get in for the yeast.
I guess my question would be, why would we use an airlock/blowoff tube on a primary & not a starter? Aren't they doing relatively the same thing?

The purpose of a starter is to increase the number of healthy yeast cells.

The purpose of fermentation is to let a sufficient number of healthy yeast cells consume the sugars and produce alcohol and CO2.

I understand the purpose of each, but aren't yeast consuming sugar, producing alcohol & CO2 in a starter as well or am I not understanding the difference? I know the time in a yeast starter is much shorter than a fermentor, but it seems like the same concept..basically just yeast doing what they are supposed to do. Isn't making a yeast starter essentially making a small batch of beer? I've been trying to read & learn as much as I can in a VERY short period of time, but after reading so much & watching so many "instructional" videos, I may have misunderstood or confused explanations.

Oxygen is needed to increase the number of healthy yeast, the problem is that oxygenated beer tastes bad. We decant the liquid off of a starter so we do not care how it tastes, so we try to ensure that the yeast have an abundance of oxygen.

During fermentation we are not as concerned with increasing the number of healthy yeast, but we are concerned about beer tasting bad, so we try to limit the oxygen to the amount that the yeast will use while consuming the sugars.
