Default Creating an NA (Or...how I neutered my beer)

I've threatened to do it and the time has come. I decided to sacrifice one half of my 10 gallon batch for the greater good of brewing knowledge.

I for one, would love the idea of having some non-alcoholic beer on tap that tasted good and was reminiscent of a favorite clone recipe.

I followed the basic concept put forth by BYO and we shall see the results in a few weeks:


We start with 10 perfectly good gallons of an Anchor Steam style Ale. 5.5% aclkeehol. Flip a coin to see which "child" looses.

Siphon into my brew pot.....gently...

I can smell the goodness. It's not too late to turn back...

On to the fire it goes...striving for a 175-179 temp range. Alcohol boils at 173.3F

At 175, the "ghost" of the krausen is awakened. At this point, there is a strange whining and hissing from the bottom of the pot. Probably due to the evaporation of the alcohol under the pressure of the liquid. Or...could be the beer ghosts screaming in agony.

Held the beer at 179 for 30 minutes. There was a definite medicinal smell in the brewshop. I had a box fan blowing fresh air in...just to keep any concentraion of vaporized alcohol from accumulating.

After a 20 minute session with the worrt chiller (sanitized in a more traditional fashion), it's back into a keg for some time to mellow and chill.

I'll tap in a few weeks and compare to the non-neutered batch and report back.

Interesting experiment. I look forward to reading about the results - not that I'd ever want to brew something that's n/a...

That kinda brings a tear to my eye... but all in the name of science. Just wondering if it will work. Keep us posted.

So, if this works are you gonna call it Biermunchers Neutered Ale?

I have two questions:

1) Why would you want to ruin a perfectly good beer?

2) How are you going to be sure that you've gotten rid of the alcohol? I've read about this technique and also seen some criticisms of it because it doesn't really drive off the alcohol. Would a comparison of the gravities of the two batches tell us something about the alcohol content since alcohol is less dense than water? (okay that's a 3rd question).

The gravity will absolutely go up. If you compare the two gravities you'll be able to figure out the amount of alcohol that boiled off.

I'll check the gravity, but I'll rely on the ole pint-on-an-empty-stomach test to tell me what I really want to know.

You know,

you could use that wort chiller and some cold water to catch that alcohol as it comes off the boiler, and increase the ABV of some other beer. Or just put it in an oak barrel and age for 3 years.

Just don't tell the ATF.


[Disclamer: this was totally a joke. I do not condone the above actions, as it could wind up putting you in jail.]

I think I caught a slight buzz just whiffing up the fumes. (by whiffing of course, I mean snorting until I bout passed out...)
