They say not to use lye because instructions need to be written for the lowest common denominator. I will try recirculating hot one followed by starsan, but might move to lye as last resort. Of you...

So after further reading, I think if you properly rinse yeast cake, and get rid of dead yeast cells, trub and any other unwanted material, then you can have equivalent yeast to a starter. You'll...

If you want to build up a lot of yeast for a large batch of high gravity beer, I can see two potential options:

Thank for the feedback. A little more details about my setup.

I usually use 1.25-1.5 qt./lb for my mash thickness. I don't get how increasing the ratio (i.e. 1.5-2 qt/lb) will result in less...

What kind of efficiencies are people getting with ToP? I'm hitting 63-67% average over last 10 batches.

Yeah, 8 weeks at 35 might be overkill, but if you have time it won't really hurt. I've been meaning to experiment with different lagering times and see if I can notice a difference.
