Reusing Harvested Yeast

[scottgar12]

I just wanted to get some opinions on reusing the yeast I harvested from my porter. Deal is that I dumped it from the bottom of the conical into a a sterilized mason jar on the 11th day after I brewed. Normally I would brew again on Sunday which would be the 14th day after I brewed the porter. However, work was a pita this week and I don't feel like brewing this weekend. I have 400 ml of pretty thick slurry in the mason jar with about a half inch of porter covering stored at about 35 degrees.

Think it will be good to pitch next week if I take it out on brewday to let it warm up like normal? It is clean of trub and I'm brewing a stout so I don't think it needs any special treatment.

Sure. I had some yeast sitting on a "hop cake" for 3 weeks. The beer on top just preserves the yeast. Just make sure you pour only (or most of) the good stuff into your fermenter.

It will be fine. Supposedly after a week or two it goes downhill, but I have found it's good for at least a month (from harvesting) provided you have decent sanitation. After a couple of months you can start getting some evidence of autolysis happening (you will know if you get it), at which point it is recommended to wash and make a starter..
