6. Most people get the coffee to water ratio wrong

The SCAA standard is 55g of ground coffee to 1L of water which works out to just about 10g of ground coffee for 6oz of water. It's best to measure by weight because the volume is going to vary depending on how fine or coarse your coffee is ground.

Most commercial coffee makers sold in the US won't even hold that much coffee if you brew their maximum capacity of water.

Most people don't use enough coffee and some use too much so you wind up with either over or under extracted coffee which results in off flavors. If standard brewed coffee is too strong for you, dilute it with hot water after it's been brewed. If standard brewed coffee is too weak for you, choose a different brewing method like espresso or aeropress.
