me either! that is so cool. I have been wanting to capture some wild yeasts for a while now. I live just over the way from Somona county where Russian River makes some awefully tasty wild brews and am curious about my local flora (fauna? is there an ‘F’ word for micro-organisms?)
Base Wert for a Wild Apricot Chantrelle Beer…Hope I do not have too much of the vomit notes, this
is gonna be the beer I pitch that wild yeast into tomorrow after my fridge drops the temp on down
to the 40"s…because this stuff spontaneously took off in the 38-40 deg f range. I am gonna try to drop
it down and see if it will start cold…
Cooling in the refer waiting for oxygen and pitching tomorrow am…
Edit: Pitched @ 47-48 degrees and keep rousing it…wants to take off…but not yet…we will check
in the morning
Edit#2; This morning, albeit slow, methinks it is fermenting. Bubbles are pootin out of the airlock ;D
Update
Today it appears to have completed it’s mission and has pooped out…so attenuation
was not that wonderful but then I gave it a high gravity start and a lot of work to do.
We came down to 1.023 today and correcting for temps approx 4.6 % ABV.
Taste is mild and fruity with a hint of peach mango which is not suprising considering the
source. Smooth and not harsh kind of sweet because of the ending gravity point more time
may change this I just do not know. Taste is …beer… I get no vomit notes.
Are you planning to warm it up a bit and see if the gravity drops further? Or maybe a different yeast? As long as you’re kegging, no problems, but I’d worry about bottling, especially since it ferments at such cold temperatures. If there’s residual sugar then it might keep working slowly in the bottles and building up pressure.
I did warm it up about 4 days ago…great minds think alike…no hurries
I caught a couple of good forceful exhales thru the bubbler this evening.
Will check Sp. Gr. again soon…
I will venture a guess and try to answer this, but your post seems off topic.
Krausen is a function of the yeast as they consume their food source.
Dramatic temperature changes can make yeast activity subside…or accelerate depending.
Head is more from the ingredients in the wort like carafoam and wheat…proteins.
And CO2 nucleation points that allow the gas to collect and rise.
