William H. Ukers, All About Coffee
“ A French china drip coffee pot is used. It is kept in a warm heater; and when the coffee is ordered, this pot is scalded with hot water. A level tablespoonful of coffee, ground to about the consistency of granulated sugar, is put into the upper and percolator part of the coffee pot. Fresh boiling water is then poured through the coffee and allowed to percolate into the lower part of the pot. The secret of success, according to our experience, lies in having the coffee freshly ground, and the water as near the boiling [Pg 691] point as possible, all during the process. ”
