They aren't 'grounds.' You are freeze drying already-brewed coffee. The instant crystals are what is in the already brewed coffee, minus water. Adding water rehydrates the coffee.

Ah, that makes sense. Thanks. I guess I've just always thought it was the grounds that were freeze-dried and somehow that made them dissolve-able.
Except for the PC instant brand where they started shipping it with grounds included. I am 99% sure they had a production problem, but their help team said it is microground coffee added as a flavour enhancer. The issue is what they ship is not micro ground powder, but large .5mm chunks of compacted tooth breaking coffee beans
Fun instant coffee whip-thing. If you haven’t already seen it, whip a table spoon of sugar, tablespoon of warm/hot water, and a tablespoon of instant coffee. It makes a sticky, delicious coffee yummy thing.
I like to whip it with sugar and heavy cream for a coffee mousse.
Dalgona coffee, if someone wants to look it up.
