The vapor coming off is actually significantly richer in ethanol that water. Where you get into azeotropes is when you're doing fractional distillation as you move up your column. i.e. if you recovered the vapor, and then boiled some of that, and recovered that vapor and boiled some of that, etc, the vapor would be increasingly high in ethanol, until you hit the azeotrope, and then no amount of boiling and recovering vapor would change your composition.

Anyways, sorry for rambling into somewhat

I stand corrected on the first part of my statement. I still don't think it will work for making a low alcohol beer.

it could be used to make a low alcohol beer, but whether it can be used to make a good low alcohol beer is another question entirely, which I think may be your point.

If you made a small beer (1.035) and mahsed really high (160F) so it would finish around 1.020 you might get a low ABV beer to do your evap technique on.

Maybe this is a noob question but how is 4.1%ABV an alcohol free beer? Or am I not understanding correctly?

Reread step 5

My instincts tell me that a pregnant woman should be able to enjoy a very moderate amount of alcohol. Of course this is horribly taboo, but the children who suffer from FAS had mothers that consumed considerable amounts of booze. I really don't see a liter of Mild throughout a weeks time amounting to any kind of risk, and I'll bet I could get the blessing of several physicians on that arrangement. The kind of beer we drink is chock full of nutrition, and I considerably different than having a couple mixed drinks every day. I would feel way weirder about my wife having a diet soda every day than a 6 ounce glass of low gravity beer.

Ok, I am thinking why go thru all the trouble. But, people would probably think the same thing about lots things I do...
So, one alternate route you could go down is making wort, then diluting with water to approximate finishing gravity of what ever beer style you are attempting, then carbing the "alcohol free" carbonated beer. So in other words, just skipping the fermentation step. The esters wouldn't be present, and I've never done this, but, sometimes my wort tastes sooooo good coming from the mashtun, I've often wondered what this would taste like in a alternate beverage form. Anyway, good luck in your quest! Perhaps you may just have to brew up and lager away some tasty congratulatory brews for after the pregnancy!
