Re: Refractometers and Methanol?
Well, I thought it was alright for a dumbed down tv show...boobs and all... Theoretically, she's right: in a distillation, the first drops out will be the 'purest'. But, that's kinda like the physicist who 'conveniently' ignores friction. So, that 'theoretic' situation only applies if you have ONLY ...

Re: Jokes
The blonde decided to try a solid deoderant.
No 'dumb blonde', her, she carefully read the directions and followed them: "Remove cap, push up bottom."
The trip to the emergency room was no fun, but her farts sure did smell good...

Re: Methanol and Pectin.
This is a tough one to get a handle on. I've done a bit of preliminary work, but then my 'long-distance-anonymous collaborator' disappeared, so I had no way to go any further. As the prelim results were unexepected, I'd rather not go into them without further work. The trouble with pectins and the p...

Re: Report on leeching of plastics into ethanol
Interesting. With just a quick look-through, I tend to agree with schnell. I do note that on page 157 they account for the 'column crap' (yes...that's a scientific term... :D ). As to any usefulness, I'll have to have a more thorough read. But, I'll have to do that for work, anyway, now that it's co...

Re: Distiller/chemist/engineering feedback needed
Question 1: Yes.
When the corrosion totally covers the elemental copper, no more crap will stick.
Question 2: No, Yes.
No "magnetic" attraction, copper doesn't 'suck'...it must physically contact the copper.

Re: Great Apple brandy: Toasted or charred barrel?
Ethyl acetate is one of the most important compounds (especially in regard to aroma) in Bourbon and most other spirits, and increases during aging. I routinely test for it and can assure you that it increases "in the bottle"... Does that apply to neutral in the 95+ range also? Not so much...

Re: Great Apple brandy: Toasted or charred barrel?
"Age" is a small word with a pile of meanings... Speculation about barometric pressure and grain orientation are interesting, but in the end, I think, specious. The range of variation in barometric pressure isn't enough to drive chemical reaction, and, in heartwood at least (which is all a...

Re: Ferment stinks like rotten eggs
Epsom salt = magnesium sulfate
21-0-0 = ammonium sulfate
Bugs + tons o' sulfate = rotton egg smell
As advised though, it's not a deal-buster. Any that doesn't 'blow off' will likely be 'dealt with' during distillation.
