ABV ? adding liquor to fermented beer

So I am thinking of brewing a low alcohol ale, possibly with some maltodextrine and spiking it with infused vodka. But I want to still end up with a fairly reasonable ABV(under 7%) so I need to determine how much that "x" quantity 40% vodka will raise ABV of 5G(or whatever batch size) of "x%" beer to. I could probably figure it out by myself, but I'm not really a math guy. Besides, I know there are a plethora of smarties here who will be glad to display their numerical prowess. I wish I would have been paying attention more in algebra. Damn.

Why wouldn't you just brew a 6% beer in the first place???

just do the shot of vodka and chase it with the beer

why would you want to do this?

I still don't understand why you want to do this, but for the math challenged:

There are 25.3 oz in a fifth of vodka.

40% of 25.3 is 10.12 oz of alcohol.

There are 640 oz in 5 gallons.

10.12 oz divided by (640 + 25.3) is 1.5%.

So, adding a fifth of 80 proof vodka to 5 gallons of beer will increase the ABV by 1.5%.

"Infused" vodka. Thanks Yuri, thats what I came up with after thinking for a minute. My initial guess seemed low until I wrote it out. How much do you think I could add before tasting the vodka? I was initially thinking about adding around 3 to 4 cups with less being better. I still want it to taste like a beer but have noticeable added benefits.

Do it an report back. I can't imagine it'll be good, but here's to hoping.

 Yuri_Rage 11-08-2007 12:42 AM

Umm...I think you'd be better off infusing the beer rather than trying to flavor it with vodka. Post the flavor you're after, and maybe we can help.

Not just flavor. Other added benefits.

Just brew a higher O.G. beer, dude.
