Does not work that way in practice. Nobody has ever removed the vast majority of alcohol from beer in a home setting and verified it analytically. I'll wait for a counterexample, but I won't be holding my breath while I wait.

Mary Beth Raines, who is a medical researcher by trade and used to own a yeast supply company, attempted several methods and each failed. She was able to do with in small quantities with lab equipment but never with reasonable quantities in a kitchen. What should happen and what does happen are often different. Personally I would verify my success analytically before giving a product to someone who is restricting alcohol consumption for medical reasons.

Aren't we supposed to believe that the vapor is mostly alcohol?

Very true... but think about doing it in a kitchen and (if you're smart about it) the hood vent on. The amounts in the air would be sooooo small that it wouldn't even be able to ignite (see: oxygen and stoichiometry)

Let's not delve into a huge debate on alcohol and pregnancy. Thanks.

"It is a common misconception that in a liquid mixture at a given pressure, each component boils at the boiling point corresponding to the given pressure and the vapors of each component will collect separately and purely."

read this http://en.wikipedia.org/wiki/Distillation and if you still feel like you can confidently remove the alcohol in a home environment, then go for it. im not saying its not possible but if you are truly concerned you shouldn't attempt it without analytical testing. if distillation were easy then they wouldnt pay people like me alot of money to do it.

Thanks for your concern. I'll update with my own taste test once the bottles are carbonated.

No. Bad. Your wife shouldn't be drinking. Are you insane?

I'm a philosopher by trade, and I think that this thread is ethically unsound.

Give a man a beer, and he'll wax prophetic for an hour.
Give him a baby, and that's a LIFETIME of material!


p.s. As a musician, I must argue that ANYTHING you cannot hear, is UNsound!

What my wife and I do is none of your business. I'm not about to debate this with you. This is a homebrew forum. I've gotten some good information from everyone in this thread, and it's up to my wife and I to decide how to proceed. I will not report whether my wife did or did not drink this "reduced alcohol" beer. I will report back on the taste of the final product from my own tasting.

For the record, I am a special education teacher who specializes in adolescents with moderate cognitive delays and behaviour concerns. This includes children with severe FASD. I'm aware of the consequences of alcohol on unborn fetuses.
