Build a better cup
The ideal temperature range for brewing coffee is between 195 to 205 degrees fahrenheit.
The grind of your coffee is important in determining the flavor. It is best to purchase whole beans and grind as close to brewing time as you can.
Use the proper grind for the type of brewing method you use.
French Press: Coarse
Espresso: Extra Fine
Chemex: About as coarse as kosher salt
Single-cup Pour over: About as fine as table salt
Aeropress: About as fine as table salt
If your coffee is bitter, your grind is probably too fine and are over extracting the bean.
If your coffee is flat and weak, your grind is probably too coarse and you are under extracting the bean
The strength of coffee is a personal choice. These general guidelines will be a good starting place for a consistently good cup of coffee. Adjust as you like to make your coffee stronger or lighter.
