Key ideas in Finding the Sweetness in Coffee
- Coffee beans are the seeds inside sweet red or yellow fruit cherries
- Gentle, unburned roasting preserves natural fruit sugars and acids in the bean
- Roasting beans until dark or scorched burns away sugars and leaves harsh charcoal notes
- Brewing coffee grounds for too long extracts heavy, astringent bitter compounds
- Standard commercial coffee often masks cheap, defect-heavy beans with intentionally dark roasting
- Scalding liquid numbs human taste receptors and masks delicate flavors
- As coffee cools toward body temperature, natural sweetness and subtle fruit notes become detectable
- Under-extracted coffee pulls only fast-dissolving acids, tasting sour and sharp
- Properly balanced coffee dissolves sugars and sweet flavors that offset the acid
- Over-extracted coffee pulls out late-dissolving bitter tannins that leave a dry mouthfeel
- Coarse grounds extract slowly and leave coffee sour and under-extracted
- Grinding finer exposes more surface area and pulls out balancing sweetness
- Too fine a grind eventually turns bitter and astringent
- Brew ratio dictates how concentrated the coffee feels in your mouth
- Skimping on water creates a dense, syrupy mud that mutes distinct flavors
- Dark roasts are brittle and porous, making bitter flavors dissolve very quickly
