In view of the fact that the United States imports coffee from more than a hundred different sections of the world, and that there are wide variations in flavor among the coffees produced in each of the hundred, it is easy to understand that the blender has an almost unlimited supply from which to make up a blend with a distinctive individuality. Practically all coffee importers, and most wholesalers, are thoroughly acquainted with the relative trade values of the different coffees, and help their customers make up desirable blends.

Small Roasters for Retail Dealers

Royal Gas Coffee Roaster for Retail Stores

While the wholesale coffee roaster is obliged to instal a large and somewhat complex equipment, the retailer must use a small, compact, self-contained unit that does not take up much space in his store, and that is easily operated. Retail roasting machines are constructed on the same general principle as the wholesale roaster. The roasting cylinder is generally revolved by electric power, and the heat is derived from gas or gasoline fuel. Cooling is by air suction in a box attached to the roaster. The capacities of the machines range from ten to three hundred pounds, the operating cost running from approximately eight cents per hundred pounds for gas fuel and ten cents for electric power. The roasters cost from three hundred dollars for the smaller sizes, to fifteen hundred for the one-bag type; and to two thousand or three thousand dollars for the two-bag type.

One coffee-roaster-machinery manufacturer has recently brought out a gas-fired, electrically operated fifty-pound miniature coffee-roasting plant designed for retail stores, which comprises a roaster, a rotary cooler, and a stoning device, that sells for six hundred and fifty dollars.

Retail coffee roasting is similar to the wholesale operation. When the cylinder has become heated, the green coffee is run in and allowed to roast in the revolving cylinder for about half an hour. If the coffee is the average green kind, the full heat may be applied at once; but if old and dry, a lesser degree is used. When the roast begins to snap, the flame is turned lower to allow the beans to cook through evenly; and when nearly done, it is almost extinguished. During the operation, the roasterman, who may be the proprietor or a clerk delegated to the work, frequently "samples" the coffee by taking out a small quantity with his "trier" and comparing the color of the roast with a type sample. When the colors match exactly, the coffee is dumped automatically into the cooler box just below the cylinder opening; and when sufficiently cooled off, is ready for grinding to order.

A large number of retailers roast coffee in their stores; and the most successful find that besides being able to make a feature of freshly roasted coffee, they can save money and increase their sales. One progressive grocer found that he was able to get eighty-eight pounds of roasted coffee out of one hundred pounds of green coffee, as compared with the wholesaler's eighty-four pounds; that he could buy green coffee at a closer price than roasted; and that it cost him less for labor, fuel, overhead, and similar items, than it did the wholesale roaster to turn out a roast.[340]
