About 1899, Dr. Sartori Kato of Tokio, who had invented a soluble tea in Japan, came to Chicago and produced a soluble coffee (introduced to the consumer in 1901) on which he was granted a patent in 1903. In 1906, G. Washington of New York, an American chemist living in Guatemala City, produced a refined soluble coffee which was put on the United States market three years later. The full story of soluble coffee in America is told in [chapter XXXI]. ([See page 538].)

The first gear-driven electric coffee mill was introduced to the trade by the Enterprise Manufacturing Company of Pennsylvania in 1900.

In 1901, there appeared in New York the first issue of The Tea and Coffee Trade Journal, devoted to the interests of the tea and coffee trades.

In 1900–01, Santos permanently displaced Rio as the world's largest source of supply.

In 1901, the American Can Company began the manufacture and sale of tin coffee cans in the United States. In this year Landers, Frary & Clark's Universal coffee percolator was granted a United States patent; and Joseph Lambert, of Marshall, Mich., brought out one of the earliest machines to employ gas as a fuel for the indirect roasting of coffee. It was in 1901, also, that F.T. Holmes joined the Huntley Manufacturing Company, of Silver Creek, N.Y., which began to build the Monitor gas-fired direct-flame coffee roasters.

In 1902, the Coles Manufacturing Company (Braun Company, successor) and Henry Troemner, of Philadelphia, began the manufacture and sale of gear-driven electric coffee grinders.

As a result of the agitation for some way to deal with the overproduction of coffee, the Pan-American Congress, meeting in Mexico City in 1902, called an international coffee congress for New York in the fall of that same year. It met from October 1 to October 30; but at the close, the problem seemed no nearer solution than at the beginning. In 1906, Brazil produced its record-breaking crop of 20,000,000 bags, and the state of São Paulo inaugurated a plan to valorize coffee.

In 1902, the first fancy duplex paper bag made by machinery from a roll of paper was produced by the Union Bag & Paper Corporation. It was of sulphite fiber inside, and glassine outside; a style afterward reversed, so as to have the glassine the inner tube.

In 1902, the Jagenberg Machine Company, Inc. (absorbed by the Pneumatic Scale Corporation in 1921) began the introduction to the trade of the United States of a line of German-made automatic packaging-and-labeling machines for coffee. Subsequently, the Johnson Automatic Sealer Company, Battle Creek, Mich., became well known as manufacturers of a line of automatic adjustable carton-sealing, wax-wrapping machines, package conveyors, and automatic scales. Among other automatic weighers that have figured in the development of the coffee business, mention should be made of The National Packaging Machinery Company's Scott machine, of E.D. Anderson's Triumph, and of Hoepner's Unit System.
