Percolator Coffee Machines

The simplest way to explain how percolator works is imagining the air bubbles that form from boiling water of the pot and their natural rising action. Once added water boils, pressure starts pushing bubbles upward the tube opening. Since diameter of a tube is smaller than bubbles, once each bubble passes, it will bring a small amount of water above it. Once water and bubbles reach the tube opening, they will flow over cover, which holds ground coffee beans. Water will then pass through coffee beans and back down into pot. Every time water passes through coffee beans; it brings more oils and essences and makes coffee richer and stronger.

Pros:

Good quality cup of coffee if measured and grounded properly

Cons:

If percolator is using stove heat, too much time on the stove can make a taste of coffee bitter; and too little time can make it “watery”.
