 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.
