Temperature
The temperature is one of the most critical factors for an espresso shot that is perfect. If the water is too hot, it could cause the coffee grounds to burn and produce an over-extracted bitter brew. The ideal temperature for extraction is 200 degrees Fahrenheit, which allows the water to extract all the coffee's desirable flavors without scorching the grounds or over-extracting.
