Default Harvesting yeast from bottled beer

I have seen a few threads where folks have harvested yeast from a bottle of beer. Could someone explain how this could be best accomplished?

Thanks

I think Google is your friend on this one. Or start with Palmer's info.

Yeah, it involves being very careful with sanitation and stepping up the size of the starter. Google it but give yourself a week to build it up to a sufficient size. I did it with a bells two hearted ale and could barley see the yeast I started with.

Just curious, how long did this take to kick off? I have dregs from six bottles of bell THA in a starter right now, been about 48 hour and no signs of activity...

I started with the dregs of just 2 bottles and had activity within 24 hours if I recall, maybe a bit more. Surprised that you haven't seen anything yet. The bottles that I has we're only 3-4 weeks old do that might have helped.

I've seen bottle harvested yeast take a day or as much as a week (old bottles with finicky strains) to show initial activity. I usually expect to see activity within 2-3 days.

What was your OG of your starter? It needs to be stepped up slowly.

I used the regular 1/2 cup DME to 2 cups water for my starter...then added the dregs from 6 bottles.

Nope, intermittent stirring.
