Key ideas in How to Brew Better Coffee
- Dark-roast coffee beans expand and lose density during roasting, making them lighter per scoop
- A volume scoop of dark beans provides fewer grams of actual coffee than the same scoop of light beans
- Weighing coffee on a scale guarantees the same amount of coffee goes into the brewer regardless of roast level
- A brew ratio around 1:15 to 1:17 yields a clean, properly balanced cup
- Using too much water relative to coffee grounds washes out the flavor into a thin brew
- Using too little water results in thick, muddy, overconcentrated coffee
- Water straight at a rolling boil (100°C) burns delicate aromatic coffee flavors and creates harsh bitterness
- The ideal coffee brewing temperature sits slightly below boiling, between 90°C and 96°C
- Letting a freshly boiled kettle rest off the heat for about 30 seconds drops it into the ideal brewing range
- Fresh coffee grounds trap carbon dioxide gas that repels brew water and creates dry spots
- Adding about twice the coffee's weight in water kickstarts the release of bubbling gas
- Waiting roughly thirty seconds allows the bubbling to subside before pouring the rest of the water
- A brewed cup of coffee consists of more than 98 percent water
- Chlorine and heavy off-tastes in tap water carry straight through into the final brew
- Clean, filtered water is required to let specialty coffee's true flavors emerge
- Water washes out acidic, sour flavors almost immediately upon contact
