Starter from dregs

[nyer]

I'm doing a sip of sunshine clone soon. I saved the dregs from 4 cans of heady topper and dumped them into a 1020 starter. 2 days later it appeared to have finished fermenting so I decanted and added some 1040 wort. How many times do I need to step this up for a 5 gallon batch of sos?

I usually start with dregs from 2 bottles and do as follows:

4 oz starter @ 1.020
8 oz starter @ 1.020
16 oz starter @ 1.035

They should be ready for your normal starter after that. You likely wont see much activity, but you should see the yeast on the bottom growing. I never decant until pitching into my final batch of beer. I always just add the additional starter right on top of the original one for my steps.

I don't know if that's the RIGHT way to do it, but I've successfully harvested close to a dozen times.
