I know we have the Commercial Beer Yeast Harvest List thread
and I asked in there, but didn't get much response. I've heard 2 people say that you can't harvest from Bell's Two Hearted. One said they use a different bottling yeast and the other said they filter.
I was able to harvest some yeast from a bottle back in October. I had activity in the starter with just the dregs and I stepped it up and I successfully made the Bell's Two Hearted clone with it and it tasted great. I also saved some of the yeast, but haven't used it yet. I'm at the point where I want to either use it, regrow some more because it's almost 6 months old or pitch it because I'm concerned I may just have their bottling yeast.
I did find this on the Bell's website
since we donít filter any of our ales either, you can harvest it directly from the bottle.
They don't specifically mention Two Hearted (probably because of the higher alcohol content making it not as good of choice as their lower alcohol beers for harvesting). But at least they gives me hope that what I have is their house primary fermentation yeast and not a bottling yeast.
So can anyone confirm or deny that you can harvest their primary yeast from Bell's Two Hearted?
