This has been fun so far, some more info: We tasted the juniper starter prior to pitching and it tasted like beer, it was nice and fruity.

Another interesting tidbit was: Before I racked and fed it the second time the juniper berries would float up and down with the yeast (actually probably the co2), top to bottom, bottom to top, sometimes they would stop in the middle and change directions, this fascinated me for about a half hour one day, yeast elevators, what can I say, easily amused.

Keep on yeasting my friends

One question tho. Does it taste or smell anything at all like gin? I hate gin and the smell of juniper berries (for obvious reasons) will usually remind me of gin. Chalk it up to a bad experience in college 20+ years ago that I will never repeat.

I am intrigued by the harvesting of wild yeast. But if this creates a flavor or aroma that even approximates gin, I'm out.

Not at all, and I wouldn't expect it to. I'm not using juniper berries in the brew, only the yeast off of them for fermenting it, you see what I'm getting at?

Keep on brewing my friends

This is a bit late but figured I'd throw it out there. I've never tried this technique, but I've read in other yeast harvesting threads about adding chlorine dioxide tablets to samples because it kills any bacteria present but does not affect yeast. They are commonly used in aquariums and so are available at pet stores (And I've seen them listed on several of the large online HBS's). Sounds like it could have been useful for you though.

For getting rid of bacteria you could wash the slurry with diluted lactic acid, ph 2. You'll find it if you look for acid wash. Even better, get into pure culture technique, so you can isolate a pure yeast clone.

I'm getting very excited about my new yeast, I got home from work yesterday and found that it has kraussen! In fact it appears high kraussen has receded, it may be a little hot in the house, appx. 78F.


I split the 1 gallon batch and added 3/4 cup brown sugar to one and 1cup to the other:


Two hours later they both went nuts again:


I mislabeled the one with 1 cup, it should be 8.83%, I'll keep building both of these alternately now to see what it's alcohol limits are.

Keep on yeasting my friends

I went out on my bike yesterday and found the motherload of juniper berries. I will subscribe the son to pick me a batch today. Looks like a fun experiment. Please keep us updated.

Yes, and surprisingly easy, a little patience and anyone can have this yeast (If you have access to the berries, probably any berries). People actually do this sort of thing all the time with wine and cider etc, right? The wild yeast on the skin of the fruits? I guess the only difference is this is culture from a few berries for use later?
