The New Math

This is what happens when you under-estimate the vigor and rate of a native yeast fermentation.

Whoa...like WHOA! I can't believe that a native yeast could be that robust! You grow them strong in those parts...

No stuck Fermento here!!
Is that Mourvèdre, by any chance? Also...wouldn't a tendency to overheat act as self-limiting (-- a little knowledge...you know) umm whatever & prevent this?
Inquiring winegeeks want to know!
See you next month, I trust. DJR

No Siree D...that is Petite Sirah. The problem with a ferment overheating is that it has a tendency to severely damage the yeast population to the point where it cannot finish out a ferment. That often happens when the ferment gets up over 100 degrees or more. HOWEVER the thermometer on that tank read only 83 degrees. And FURTHERMORE, a sample out of the center of that roaring behemoth read at 92 degrees. Which is within acceptable limits for a peak fermentation.

!#@$*% Gaw-Damn! Major spewage! So what's the new math add up to, Professor Fermento, i.e., how does an instance like this factor into your expectations for this P.S.? (I'm just as curious as David J.)

The fact that it has done this is neither here nor there...although I am somewhat of a newbie with native yeats fermentations. The ferment seems to have only suffered from a roughly 20 gallon volume loss. The correct answer to your question is...wait for it...I dunno! But I'll endeavor to keep you posted.

I feel like an idiot-- love Mourvedre, must've been delirious, back o'my head I *know* M- is a notorious late-ripener...
Thanks for sharing! Way cool. Only theoretical prob w/ a *hot* ferment
(--so up to 99ºF won't kill th yeasts & process pushes through?)
--as I remember, is losing aromatics, though fruit gets pumped up, right?
Rooting for ya, & bet I'm not alone! DJR

...matter of fact, if my back feels like it can handle whatever, I'll follow election results & help cart Mourvedre around, if you'll have me!

Reminds me of one slightly inebriated xmas eve when i unknowingly put dishwashing liquid in the dishwasher....I kid you not. :-)
