How you can make cold-brew coffee in under 3 minutes using ultrasound

I don't want a kitchen (or a house) full of goofy electronic gadgets that will break constantly. My gas stove, steel kettle, plastic cone, paper filters, and a can of Peets is long-term reliable, even if a solar storm takes the power out.


I've just finished my first cup, so gotta go.

New South Wales takes it's coffee seriously, and Star Bucks went bust in Australia, though I think one store survived to keep American tourists happy, though if they stay longer than few days they get converted to proper coffee. When Covid-19 made it too dangerous to got out to our local coffee dealer, I had to buy an Expobar domestic espresso machine with a properly regulated heat exchanger (it wasn't cheap and came from a specialist supplier), and my wife negotiated her preferred coffee grind with Campos Coffee (which got going selling coffee to Sydney University students and is now the most reliable dealer in Sydney). She had to send a batch or two back before she reliably got what she wanted.

Jan Panteltje is reporting on the lunatic fringe of the local coffee culture. Our local coffee dealer did offer cold-brew coffee to people with that specialised taste, but they never seemed to sell much of it.

Coffee should be black as the night, hot as hell, sweet as love, and consumed instantly. No cold, 24-hour old brew for me, thank you nicely. Italian style espresso is what I like best.

All correct except for adding some cream, and savoring two cups for a while. "Instantly" is over way too soon.

We don't get tired of coffee. We don't get tired of things that are addictive.

It is interesting. Anyone criticizing the method, should read the article first, and then criticize with precision.

Me, I am curious and would like to taste it and do my own comparison.

I wonder if the tasting was double-blind.

Yes, we can't judge the flavor from a written report.

We have an expresso machine and a coffee bean grinder, and someone gave us a giant electric coffee pot thing; none are ever used. Too much hassle, too much junk.

Some days I make two different kinds of coffee, Peets and CDM, and some days even three, with dcaf for a regular guest. One kettle, three pots, three filter cones, all working in parallel.

Me too. "Hot as hell" is silly. It would burn your mouth. Sweet as love is equally silly. Coffee is transient and love lasts (for a while at least, and for a lifetime if you get lucky).

Yuck.

Coffee isn't addictive. Caffeine is, and I was addicted to it back when I drank tea. Coffee is usually imbibed at less than the addictive dose rate. We don't get tired of things that are never quite the same and coffee beans are never entirely identical.
