Are the trees ready for careful tapping yet?
Lots here. Birch sap/syrup commercial operations. Syrup has the same smoky taste as you smell from a birch wood fire.
Can be fermented into an absolutely skull-busting wine. Pain in a glass.
That's interesting. Never knew the sugar %. Birch syrup must use enormous volumes.
There are lots of fermentation products other than ethanol. Explains why all the fuss and bother for specific yeast varieties,
even for breads (aka 'sourdoughs.') Low yeast concentrations, overnight cool fermentations, poolish, all add significantly to the flavor
of artisan breads.
I'd pull a gallon of juice and make a started of burgundy yeast. That way, my yeast of choice could overwhelm any wild yeasts that made it past the sulfiting of the must.
Some yeasts even make methanol (CH3OH). Metabolize that, starting with pulling off a pair of hydrogens. HCHO is left. You all know that's formaldehyde.
Lots of biomolecules self destruct at far lower temperatures that 100C boiling water. Hard-boiled eggs don't hatch.
I can kill most proteins at 60C or less, of even a sudden (and irreversable) drop in pH Ceviche?
Change the shape, change the function. Even the urea in urine is very effective afaoinst protein sting from jellies and coral polyps.
The birch water:
Might not even be Betula papyrifera. Maybe, it's a Russian import?
What's on the label? "Product of Xxxxx"
Canada #1 Fancy is for your table. Canada #4 is for cooking (sauces, marinades, glazes).
I admit to liking the #4 for the stronger taste.
