Should I start with the basics like grinding and extraction?
I assume, those bags contain whole beans. If so, you need a grinder. You also need something like a V60 or an aeropress to handle the extraction and filtration. Oh, and using a scale is highly recommended, but not strictly necessary.
If these things didn’t sound familiar, you’re in for a wild ride. This rabbit hole goes deep.
I grind coffee, I know how to extract, I have a French press. This is not instant coffee, but it does not mix in the press, cowboy style or boiling it in water.
Fun fact, depending on the water and the cup, it is possible to super heat water in a microwave so that it has reached boiling point but it's not actually boiling. Tossing anything into a cup like this will cause the water to violently boil often causing burns.
