Hey all,

How long until I shouldn't wash and reuse yeast from primary?

I usually keg my beers after 10-14 days and then wash and reuse. I have a batch if brown ale that has been in primary for 4 weeks now. I've never harvested from long primaries...

What do you think?

Thanks,
cranny

4 weeks shouldn't be a problem, I've done it before. Can't tell you where the "line" is, but at 4 weeks you should be safe. Especially if you make a starter with the washed yeast, like you should anyway.

4 weeks is fine. I always do at least four week primaries, sometimes five. Never had a problem with harvested yeast.

I reguarly use washed yeast from beers that spend 4-5 weeks in the primary. Never had a problem with the washed yeast.
