For some reason I think of it as an older concept. Now Starbucks and coffee chains are popular.

Highlighting carlcook’s advice:
dissolve in cold water, ONLY THEN add hot water. The rationale behind it is that aromatics evaporate too quickly when the instant powder is infused with too/boiling hot water.
Nespresso machines are definitely pressurized and temp controlled. Keurig, less so.
I read something somewhere once (great source, right?) regarding Keurig temps, and they weren’t consistent or optimal. And the pressure is more like a hose with an attachment as opposed to a pressure washer.
Some K cups will empty out when you use them, too. From what I’ve run into, that’s typically the fancy flavor ones. But some are just coffee grounds that get a suboptimal water flow at suboptimal temps going through them.
Someone can correct me on what I’m remembering though.
