How it works
The Santos vacuum coffee maker has 2 pots sitting atop one another, the bottom containing the water and the top containing the coffee grinds. As the water on the bottom is heated, the water travels up to the upper chamber through a narrow tube. The upper chamber contains the coffee grinds and as the water travels up, the grinds and water mix together to form the coffee you drink. Once all the water is done boiling, the upper chamber will be full of coffee and will travel back down the tube to the lower chamber, which is ready for pouring. This type of coffee making was popular in the mid 20th century before the drip maker became widespread. Many coffee connoisseurs feel that the vacuum method is the best for creating a quality brew, as your coffee is made without coming into contact with any plastic, metal or other materials that might affect the taste of the coffee.
