I learned enough to know what I like, what I don’t like, and what doesn’t matter to me.

I don’t like expensive coffee that use “fruit” descriptions to their flavors. I like the expensive ones that use “chocolate” or “nuts” descriptions.

I like anything from 1:12 to 1:16 ratio (in my routine, 9g to 12g of coffee to 150ml of water).

Grain should be fine, but I don’t need a precision grinder.

Precise water temperature doesn’t matter much.

I like pour over. Not so much french press, aeropress, espresso, or moka pot. I still drink it, just prefer pour over.
