I'm confused, that was an informative and useful article. What the hell is it doing here?

Ah yes. It's the cavitation bubbles that do all he work in a blender, not the blades slicing through everything at 1000 rpm.

So has anyone put charcoal and cheap whiskey in an ultrasonic cleaner to make aged whiskey?

You could get something similar by vigorously shaking them together in the bottle. Not saying I think it would work better than simply mixing (with fine powder charcoal) and filtering, though.

I know of people working on pressure cycling to simulate the daily change in temperature moving things in and out of the charcoal.  But ultrasonic cleaners work by making caviation bubbles.  So I thought perhaps it'd sonically take thing back and forth through the charcoal interface.

/mixing powdered charcoal and filtering was the make your own top shelf vodka thing.  Or pour it from a Britta filter pitcher

Cavitation bubbled is what allows things to be "whipped" and creamy.  The blades alone will just leave everything as a soggy mess.

Do you want pitting? Because that's how you get pitting?

I tried some of that.  Mostly it tastes like cheap whiskey filtered through burnt ass.

This abstract hints at an interesting aspect of cavitation. It may be induced or at least greatly affected by cosmic radiation.

When a blender creates cavitation bubbles with its violent motion, the collapse of bubbles creates a smooth puree or a rich emulsion of the foods in the blender, according to ChefSteps.

I was going to ask how ChefSteps knew this with certainty but they actually do a good job of explaining the phenomenon; it's not rigorous scientific proof but I'll take it.

it works with charred oak cubes. You can also use one to make vanilla extract in about an hour instead of 6 months of steeping vanilla beans in vodka.

They speed up any extraction process immensely.

It's neat to see the gases get compressed by the inertia of the rushing water, and then re-expand.

There's a way to make cavitation happen faster than the speed of sound.  When it happens, you get a little bit of blue light.

/at least, I remember an article that claimed that it was due to the water exceeding the local speed of sound
/whatever: bubbles making light.  neat stuff.

It looks like wiki thinks it's the heat and pressure but kinda says no one knows. The blue water / speed of light thing sounds more like https://en.wikipedia.org/wiki/Ch​erenko​v_radiation

"electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium."

I might have been misinterpreting what you were asking that first time. I was thinking you wanted to purify the alcohol (remove non-ethanol byproducts) using activated charcoal. However, by adding burned wood you are adding flavors which are impurities, but still it would make sense that if you're talking about chunks of burned wood and not pulverized activated charcoal, the ultrasonic energy should help disperse the bits of sugar and such that are in your wood chunk. The same way it disperses bits of burnt hydrocarbons stuck to an engine block.

It'd be handy if you set up an experiment for time, temperature, etc. if you actually did this. If you ran it long enough you'd probably have burnt wood booze-soup vs. whiskey so there has to be a sweet spot.

Or dial it up to 11 and try to cause fusion with bubbles. Or not.

"Eventually, an investigation by Purdue University found that Taleyarkhan had engaged in falsification of independent verification, and had included a student as an author on a paper when he had not participated in the research. He was subsequently stripped of his professorship. One of his funders, the Office of Naval Research reviewed the report by Purdue and barred him from federal funding for 28 months."

Fun stuff.

Speed of sound, not light.  Makes a lot of heat which gets emitted as light.

Which, I'd think the light would be red, not blue, but then I didn't build the farking thing.

I've done it with wine and playing around with vodka to see how much color and flavor I could get.

I didn't do it nearly as scientifically as you're talking; I was just trying to get an idea how one of my wines would taste with a heavy oak vs a medium oak and instead of running two batches and waiting 6 months, I ran two glasses for an hour or so.  Worked great.

You can get oak chips and cube's pre-charred or uncharred depending on your end goal.
