I'll repeat my comment from the previous discussion, as ultrasound can be used to extract many things quickly: Alternatively you could use a (quite affordable) ultrasonic machine designed for gentle cleaning of jewelry, dentures, glasses.. I've used one to extract fragrance from biological material for an artistic project[0], and it worked really well. Instead of having to wait for a few weeks for a tincture to finish, you put the same tincture (alcohol and material you want to extract fragrance from) into a plastic bag for just 15 minutes. Sure, it smells not quite the same, but the speed is often worth it. I've even heard about some guy trying to turn vodka into whiskey with an ultrasonic machine and wood chips. There are quite a few ultrasonic machines on the market. I've tried EMAG and multiple Chinese no-name machines that are just as powerful but cheaper. Sadly the no-name machines are quite a bit louder - you can't stay in the same room while it's running basically. Still, they all work well for this kind of fast and dirty extraction.

A long while back, I looked into how viable ultrasonic acceleration of the “aging” of Dit Da Jow (https://en.m.wikipedia.org/wiki/Dit_da_jow https://en.m.wikipedia.org/wiki/Dit_da_jow) would be and had come across a paper looking into it the same. If I remember correctly, while ultrasonic treatment did a decent job of quickly extracting the various chemicals from their carriers, there were some caveats. The ratio of chemicals extracted could differ from normal, and it only did a partial job of accelerating the formation of very complex secondary compounds that form when the whole mix is properly aged. So the difference in smell you found could be some chemicals being preferentially released over others, and/or the lack the secondary chemicals.

  Indeed, it is after all more of a mechanical extraction than a chemical one. I remember seeing tiny bits of grass floating in the tincture after extracting the scent of fresh grass - the cavitation bubbles practically shattered the cell structure of the plant, and a dusty green soup was floating around the blades of grass.

According to the autogenerated timeline in search results, it includes coffee as well.
