For those who prefer the pleasures of percolated coffee, there's no better way than the old school method of preparing it on the stovetop. All you need is the right percolator coffee maker, and the Primula Coffee Percolator is crafted of aluminum with old-fashioned simplicity and durability. A coffee percolator works by stimulating the heated liquid from your coffee grounds, reheating it and circulating it over the grounds over and over. The percolating effect of repeatedly passing coffee over the grounds delivers a significantly different flavor and strength than traditional automatic drip coffee makers.
