Z Bob's Angel Blaster

If you are putting something to distill, drink or eat that you don't know where to put it, then put it here. Let us help you decide.

I went ahead and built one,

Put a bypass on it from the start because in his book the point was stated that this should be a violent push of air and as common sense would show it could push contents out of a container. I have 15 gal kegs filled to 13 gals then sticks added to that. There is not much head space. With the bypass you can set it and forget it. I have used it a couple of time over the months and can definitely smell what ZBob describes in his book. Even though I believe I make conservative cuts on the front end there are nasties in there.

I was just wondering of those who use this thing, how often do you apply and for how long?

Thanks.

Never seen this before. Can you describe what it is and what it does - a link maybe? Per your write up, I assume it's used in the aging process.

Hey, Pa,

You're living proof that if somebody throws an idea out on the forums, sooner or later it'll come back better. Your angel blaster is way slicker than mine, and not that I'm doing commercial, I'll steal your idea back, if that's ok.

Before I proof vodka (and gin base) I blast once, for perhaps 2 minutes. amd it seems to "soften" the vodka. Customers comment on that. For the aged Irish, I blast for a couple of minutes after the white goes into the carboy. After a few months aging, I oxygenate the whiskey gently with a stainless airstone and O2, to hasten oxidation of the wood compounds to mellower compounds.

SC, the angel blaster comes from my trying to replicate all the aging processes that occur while aging in a barrel in a rick house. One of those processes is evaporation through the slightly porous oak barrel, which fills the rick house with what we call the angel's share. This is beneficial for exactly the same reason that a potstill evaporates selectively, with the harshest compounds coming more heavily at first. Passing air violently through the spirits effects this cold evaporation.

ZBob, take it and run my friend. I just thought I'd modify it to suit my application. For long term aging, say three to five years aged in stainless kegs, would you continue to blast or oxygenate with the stone and O2? I am building up stock for longer term aging and would like an informed opinion on this if you have one. BTW, I'd like to hear any opinions.

Thanks Folks.

Here you go S.

It's damn fine book and you'll read it more than once.

Pa, I'd blast once when the liquor goes into the aging vessel, wait until the wood compound extraction (using color as a gauge) is far advanced, maybe 5 or 6 months, and then oxygenate once.

Then wait as long as you can stand it. :D

Z Bob, when you go 2 minutes in a carboy, what volume is that? Does blasting time increase with increased volume? Would the same apply to the O2 and air stone? Thanks.

Pa, that's with a 7 gallon carboy. I've never had a chance to do anything larger, but just pulling it outta my ass, I think I'd double the time for double the volume. This isn't very scientific or hugely researched, but I think I'd do the same for oxygenation.

All that uncertainty notwithstanding, the 2 processes work, and the liquor gets better. Sorry I have nothing more definitive. If you can nail it down further, let us know.

Z Bob, that seemed to be the logical leap. Everything is on oak now. At 6 months I'll give it the O2 treatment and see what gives.

Thank you sir...................
