Mate, just use a beer hydrometer. They're only a couplea bucks and they take alllll the guesswork out of it
I looked for one today @ a wine shop and no luck.
I did find a vinometer though.
I tested the turbo sugar wash and it showed 22%, the sweet feed mash showed 13%.
I'm sure it's off a little, probably 20% top and 11% on the grain because my Alcometer showed 11 or 12 on the grain.
My equipment didn't show today but is supposed to be here tomorrow acording to the tracking number.
I'm pretty excited too.
I stopped buy a friends house to get borrow an extra gas bottle until I find out how buch I'll be using.
He had a little left of a jar of stuff that went around about 3 or 4 years ago that was the cats A$$.
I ask if I could get a smell so to prime my nose (because I knew it was the best I've had), he got it down
and said "hell, take a taste too" I took a small taste, maybe a half shot because he had less that a pint left. It was as good as I remembered.
Very smooth and taste almost like a weak honeysuckle that lasted only a second or two.
maybe one day I'll get someting close.
