Temperature
The temperature is one of the most critical factors for a great
espresso coffee machine home shot. The water that is too hot can scorch the coffee grounds, resulting in bitter coffee. The ideal extraction temperature is about 200 degrees Fahrenheit which allows the water to extract all of the desired flavors of coffee without scorching the grounds, or over-extracting.
