It's not "Literally" stored inside the vessel like a liquid (that'ld be ALOT of semen!). There is a rack in there holds the individual containers. Anyway... Being stainless you could clean it properly... but that vessel probably isn't something you would use for brewing purposes anyway. About the only thing it might be good for is yeast collection for a small brewery.
Women are like yeast... You gotta keep them at the right temperature if you want to get anything out of them!
