As brandies age, chemical interactions between the spirits and the wood casks they mature in grant them their distinctive hues, scents and tastes. These reactions are slow, and aging high-quality brandy currently takes several years.
Previous research found that ultrasound waves can help extract chemicals from plant tissues. Ultrasounds are pressure waves that cause tissues to rupture, releasing bioactive compounds stored within cells at a higher rate. As such, researchers wanted to see if ultrasound waves could help accelerate the aging of brandy.
The scientists flowed distilled wine through American oak chips. As the wine seeped past the wooden chips, the researchers blasted it with ultrasound waves. The researchers found that after only three days of ultrasound treatment, they produced spirits that were similar to brandies aged for years. The scientists will detail their findings in the May issue of the journal Ultrasonics Sonochemistry.
"Obtaining, in three days, a spirit with characteristics near to two-years-aged brandies was something really unexpected for us," says study co-author Valme García, a professor at the University of Cádiz in Spain.
Eight trained judges, including some of the researchers, deemed the resulting spirits nearly as good as traditional brandies. "They tasted surprisingly well, with good fruity and sweet flavors and a high aromatic intensity," García said.

As far as 3-day old Brandy, I'm guessing that the French will have something to say about how it can be labeled (but I'm not going to predict what they will say).

Actually it looks like '72 was a good year for music. Looking at the top 100 songs of 1972 [wikipedia.org] I can hear 90% of those songs in my head, and actually liked 70% of them.
Most times when I run across these lists I remember maybe half the songs, and like much less. Then again, I've never been a top 40 listener. What the radio calls "deep cuts" I call "best stuff on the album".

That's coz you're old ;). If you were a bit younger you'd look at 1982 and say the same thing: https://en.wikipedia.org/wiki/Billboard_Year-End_Hot_100_singles_of_1982 [wikipedia.org]
Some kid today would probably say the same for 2012 : https://en.wikipedia.org/wiki/Billboard_Year-End_Hot_100_singles_of_2012 [wikipedia.org]

Only the 72 chart has Roundabout by Yes, so it's the only one that matters.
