Obviously one can harvest yeast from the fermenter, but has anyone ever harvested the yeast out of a beer bottle? I see no reason why it can't be done. Sure there is not as many yeasties in a bottle vs a carboy or the like, but with a little love they should be able to multiply to large enough quantities for the desired purpose.

It seems easier to me than washing your yeast. Thoughts?

It's a popular thing to do down in Australia with the commercial cooper's ales. You'd have to visit their sight to see how they do it. http://www.coopers.com.au/ But they do it in the bottle down there. It'd be just as easy to swirl the dregs in the bottle around to dump them into some small amount of wort to culture them. Seems to me,anyway,to be like a small starter. Similar to yeast washing. Some over here have done it with bottles containing the Pacman yeast,SN I think?

The small brewing book that came with my brewing kit has a section that explains how to do it. I am at work though and do not have it with me. Just wanted to tell you that it is possible and im sure someone will answer with more details. If i recall its very similar to making any other starter.

Yeah,washing yeast or culturing from the bottle,as I remember,are about the same. I just forget how the Aussie's did it in the bottle. Been a while. I think they just add some wort to the bottle & cover with sanitized foil.

I seem to have been successful with this by simply adding a touch of yeast nutrient and some sterilized water and DME. To grow I added a stir bar and placed on the stir plate for 24 hours then pitched into a 1 litre starter.

Albiet the final results aren't in yet, I haven't brewed a batch with it to determine if it was a good harvest, but that is coming soon and I will report here.

I divided up the 1 litre into 4 small jars and stashed in the fridge.

If you grab the sediment from a few bottles and keep your starter gravity nice and low (1.020 or so I've heard as opposed to your usual 1.040) this can be done for sure. I personally wouldn't worry about washing (unless you have a ton of trub at the bottom).

Just my $.02

I have harvested yeast lolemthos before and then gone on to do full batch.

I tried a hard cider with the 3068 weihenstephan yeast. The yeast didn't make a noticeable difference to.the cider...
But I did reculture the yeast Fe a bottle, stepped it up once and then used in a full length 20litre batch

I just made a starter with yeast I harvested from some Ommegang Abbey Ale bottles about 2 months ago. I harvested the dregs of 4 bottles and stuck it in the fridge and forgot it. I realized last week that it had been 2 months and figured I had better get something going. I pitched it into a .5L starter. With no sign of life at 36 hours, I was going to give up. I came home from work ready to dump it and found a little bit of foam around the edges so I let it ride. By the next morning there was 1/2 inch of krausen that stayed for 2 days. It's crashing in the fridge right now. I'll decant and step it up a couple more times and then try it in my next Belgian.

So, yes, it can be done.

I have to say, learning new skills and gaining knowledge in this hobby makes me proud sometimes. Here's one of those moments.

Cheers
