HowStuffWorks “Making Clover Coffee”
“The Clover uses a proportional integral derivative (PID) controller to create the exact right temperature of water every time. Even a change of a few degrees in water temperature can make the difference between a cup of sludge and a cup that highlights the flavor of the bean. If the water is too hot, it will overextract the flavor of the beans, resulting in a bitter taste, but if the water is not hot enough, then you have underextraction and a weak cup of coffee.
This coffee maker also lets you dial in the exact number of seconds that the grounds are in contact with the water, and the Clover’s brewing process is designed to bring out the best in the grounds.”
Cafe Grumpy in Greenpoint, Brooklyn has one of these magnificent machines. I’ve never had drip coffee more flavorful. See you at 2:30, baby.
