Key ideas in Better Coffee at Home
- Coffee beans vary in size and density based on roast level
- A scoop of dark roast weighs less than a scoop of light roast
- Weight provides a repeatable measurement regardless of bean type
- The 1:16 ratio means 1 gram of coffee for every 16 grams of water
- 30 multiplied by 16 equals 480 grams of water
- 1:16 is the standard baseline for a balanced brew
- Why a scale is superior to a scoop for consistency
- Applying the 1:16 ratio to a specific volume of water
- Increasing the amount of coffee grounds relative to water increases strength
- Water makes up about 98% of a cup of coffee, so its quality dictates the final taste
- Changing the brew time or grind size affects bitterness, but changing the ratio affects intensity
- Chlorine and other chemicals in tap water mask the delicate notes of the bean
- A 1:15 ratio will result in a more concentrated, stronger-feeling cup than 1:16
- Excess minerals in tap water can cause over-extraction and harsh flavors
- Using ratio to adjust strength without changing extraction quality
- The impact of water quality on coffee flavor
