The azeotrope is 95.63% ethanol and 4.37% water (by weight). It is a positive azeotrope thus reducing the boiling point of ethanol from 78.4°C this down to 78.2°C. at normal atmospheric pressure. At resort altitude the boiling point will be a little lower. If the mixture is warmed gently and not left stewing open to the atmosphere then it should retain most of its alcohol.
edit laundryman, you beat me to it.

laundryman, It is not boiled for goodness' sake! Gentle warming to raise the temperature but not hot enough to boil off the alcohol. If they are boiling the stuff you drink, then find a better provider, preferably one who knows how to make it properly!

And love to help out and answer questions and of course, read each other's snow reports.

laundryman,
Oops. All the more embarrassing as I have a first in Chemistry!
Still, that was 20 years ago...

chemistry, he (Laundryman) was making a joke of that

You know it makes sense.

Shimmy Alcott, I think chemistry was referring to an earlier post of mine.

Have we all been on the vin chaud? I feel a tad confused suddenly!
Will definitely give Jaegertee a try then.

there is a good bit on wikipaedia about azeotrops that I think I will treat myself to and do some revision on them when I next get half hour spare.  |
Given the error in my earlier post, perhaps I should do the same! Will there be a test?

You could roughly estimate the alcohol difference between pre and post boil/heat by measuring the gravity with a hydrometer before and after to provide an estimation of the alcohol change.
If you were geeky enough (and had a good supply of wine!) you could experiment with heating to different levels for different times to see what the optimum is for alcohol retention (and flavour maybe, as if that's important )
