The alcohol taste of most extracts was brought up many months ago, but I'm not so sure it was fully discussed, so I'll add some thoughts.
Alcohol evaporates at approximately 165 degrees Fahrenheit. To remove the alcohol, one would just need to bring the extract to about 170F and keep it there for a little while. I would do this in a double-boiler arrangement.
My UNTESTED THEORY about how to do this follows. Use at your own risk! I think I'm going to try this within the next few days, if I get a chance
Take the extract, preferably in a glass jar, and remove the cover
- Ideally, use a small Pyrex container, like a chemical beaker
Grab a small pot
Put something - a small plate? - on the bottom of the pot
- This will serve to keep the extract jar away from the hotter metal bottom of the pot
Place the bottle of extract on the plate/whatever
Fill the pot with water, at least halfway up the extract bottle
- Be careful not to "float" the extract bottle
Heat the pot of water slowly. Medium flame at best, 1/4 flame even better
Do not let the water boil! You really want to keep it below 180F
Test the temperature of the extract occasionally. Keep it 170-175
Add cold water to the pot when the level gets to low, or the extract gets too hot
- Add slowly, and do not let the cold water touch the hot extract bottle!
Once the extract hits 170, 5 or 10 minutes is all it should need to evaporate the alcohol
- It shouldn't hurt to leave it 15 or 20 minutes
- Theoretically, removing the alcohol will drop the height of extract in the bottom. 35% alcohol is 1/3, so if the height is reduce by 1/4 that should be enough.
- I wouldn't leave it at 170F for too long. 20 minutes?
The glass extract jar will have to cool slowly so that it doesn't crack. You could carefully remove it and let it air-cool. Or leave it in the pot for a couple hours. Do not cover the extract bottle until it is cool enough to easily hand-hold.
Worst case of this method is a ruined batch of vanilla extract, but I can't see how it would make it totally useless if you ever use it for baking.
At the very least your house should smell freaking fantastic.
AGAIN, the above is my untested THEORY. I'm no chemist, or chef, but I know quite a bit about alcohol due to my years of studying (and blogging) about rum. (See my sig below.) I have done many infusions over the years, and vanilla has always been one of my favorites, so I know a bit about vanilla, too. Again, I'm no expert, so use this info at your own risk.
Or, wait until I get a chance to test it and report back. If I never post again after Sunday night, DO NOT attempt the above.
