yeah, that would be quite handy.  in my tepache thread, I bottled it with some cane sugar, and I have them all in the sink... I don't trust them at all.  one especially, it's going nuts in the bottle and is actually releasing pressure out of the crown cap... :o
Sounds like it's time to chill and drink that one ;)

I love your experiment!  It's a cool attitude that you have toward brewing.  My 2 favorite parts of the whole scenario were:
1) Something spontaneously fermented in your fridge, and your first instinct was to drink it  ;D  Only a homebrewer...
2)  I like how the "vomit" character of your wild yeast only seemd like a minor setback... which paid off 
Awesome job!

Ok, Thanks for that brewmasternpb.  BTW, that vomit character was a possible and never as of yet manifested in this strain      It is now however in secondary and that is where Keith said these instances occured for him.
 I forgot to update. I elected to try Tom's advice and It is now kegged,
in the stainless, under 25 psi of CO2 carbing up...I added 1.7 ish ounces of Apricot Extract to the beer....
the recommended quantity for 2 gallons...beyond that, I do not know....we wait.... ;)

ryang, there is more enroute, just needs a bit more time...I can tell you this

The beer SMELLS incredible fruity and like apricot, and then the flavor is well, beer.

So you hoist this up to your nose, and it smells so good and then you get a taste,
and you are expecting the aroma to carry over and it does not...it is just good smelling beer....
not bad tasting, but not anything like you'd expect. 

Tom has plated a sample and needs more time to know what grows on the media.
I am sure he will update us all with that information when it is obtained.

I told Dave, I looked at it under a microscope and it appears to be predominantly yeast.  Right size and morphology, some were budding.  There was some debris that made it hard to tell what else might be in there, and anyway, a little bit of bacteria can have a large impact on the beer, which can make them hard to find under a microscope if they're not isolated.

So I've plated it to some yeast growth media, but bacteria might grow on it depending on the strain.  I'm growing it kind of cool, around 20C instead of 30C.  It was growing the fridge though, so that should be fine.  I also plated it to one with an antibiotic that will kill any bacteria but not affect the yeast, so I'll have a purified strain(s?) to play with.

I still need to grab some LB plates to plate it to, I only had ones with antibiotic available.  That will favor bacteria, since there is no sugar for the yeast to grow.

So if it's a new strain, do you get to name it?  B. V8ensis?

I have a particular F word I use when I find micro-organisms in my beer.  Not really appropriate for the forum.
Great posts.

Would it be worthwhile to make a completely neutral wort to see what base flavour characteristics this would impart?  Or maybe you covered that in the starter when you tasted it ( your mushroom flavours).

Anyway, fantastic idea.  You created a new beer style and discovered carbonated V8.  Just don't tell the V8 people or you'll end up paying a royalty or something.

I got an LB plate with no antibiotic, so I'll plate the solution and see what grows.  Unfortunately I couldn't find any with an antibiotic that will kill yeast and not bacteria.  Still, the lack of sugar in the LB plate should limit yeast growth.

me< Leaning more toward forganism... :D :D :D

Edit:

oscarvan, I get it now;
F =  Forganism
O = Orange (it's color)
A=  Apricot
M=  Mild
A=  Ale

I'll try to put up another photo of this beer.

I'll try to put up another photo of this beer. 

As promised

Smell of fruit like apricots and perfumey
carbonated bite on front of tongue
Little to no hops
slightly bitter with fruit present through out reminescent of apricot kind of...
long finish difficult to really nail a description but a good thing.

I took a series of pics, but they all look more or less the same.  The morphology is very clearly yeast, with no rod-shaped bacteria evident in any of the samples I observed.

The pic below is from a 10-fold dilution of the sample 1vertical sent me.  There are some cells that are clearly budding, many are not, but the mothers and daughters may have been separated by vortexing when I mixed the sample.  That large clump in the middle is just detritus of some sort, there are smaller bits visible as well.



My apologies for taking so long to get a pic of this yeast, I'm mostly working in a computer lab now wrapping up my PhD, and I don't get over to my yeast lab much anymore.

I have a few beers from this yeast left in that keg not many...then I gotta decide
to brew with it again or shine it on...(leaning toward shine it on)

Edit: Thanks so much for your contribution Tom
