FWIW, I understand freeze-drying. My question is more about how instant coffee is prepared versus brewing. When you brew coffee, you run the water through the grounds while filtering them out. When you make instant coffee, the grounds just dissolve into it?
What am I missing here?
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
