Dried yeasts

Post by Martin the fish » Tue Apr 29, 2008 2:14 pm

Are you able to take the krausen off a brew thats had dried yeasts pitched and re-use it? I have used MG and S04 on my last and it really is going like the clappers. I've never had a brew continuously bubble the airlock, usually there is a small delay but this time it is just a constant stream of bubbles.
Wouldn't mind re-using this if it's viable. 8)

It should be fine*. It's generally said of dried yeasts that they lose their viability after the 3rd or 4th generation. I've repitched dried yeasts a few times before with no problems.


*Assuming there are no contamination issues that is. Most people prefer to use fresh if using dried yeast as it's quite cheap and not worth the risk of infecting beer.
