The recipe for a great cup of coffee calls on four principles: Proportion, Grind, Water and Freshness.
- Proportion: Use the right proportion of coffee to water. This is the most important step in making great coffee. For the most flavorful cup of coffee, Starbucks recommends two tablespoons of ground coffee (10 grams) for each six fluid ounces (180 milliliters) of water.
- Grind: The shorter the brewing process, the finer the grind. Different brewing methods have different grind requirements, so grind your coffee for the brewing method you use.
- Water: Use fresh, cold water heated to just off the boil. A cup of coffee is 98 percent water, therefore the water you use to make coffee should taste clean, fresh, and free of impurities.
- Freshness: Use freshly ground coffee. The enemies of coffee are oxygen, light, heat, and moisture. To keep coffee fresh, store it in an opaque, airtight container at room temperature. Note: Storing coffee in the refrigerator or freezer for daily use can damage the coffee as warm, moist air condenses to the beans whenever the container is opened.
