All Rio coffee is described by the name Rio; but the American trade recognizes eight different grades, designated by numerals from one to eight. These grades are determined by standards adopted by the New York Coffee and Sugar Exchange, and are classified by the number of imperfections found in the chops exported. No. 1 Rio contains no imperfections, such as black beans, shells, stones, broken beans, pods or immature beans ("quakers"). Such a chop is rarely found. No. 2 has six imperfections. No. 3 has thirteen. No. 4 has twenty-nine, No. 5 has sixty, No. 6 has one hundred and ten, No. 7 has two hundred, and No. 8 has about four hundred, although on the Exchange these last two are graded by standard types.

Victorias. Up to about the year 1917, Victoria coffees were held in even less favor by American traders than were Rios. As a rule the bean was large and punky, of a dark brown or dingy color, and its flavor was described as muddy. Then, the coffee growers began to introduce modern machinery for handling the crops, with the result that the character of the produce has been much improved, and the demand for it has been steadily growing. Many roasters who formerly used Rios straight for their lower grades, have changed to Victorias, not only to improve the appearance of the roast, but to soften the harsh drinking qualities of the low-grade Rios.

Bahias. Until recent years Bahia coffee has been decidedly unpopular in the United States, largely because of its peculiar smoky flavor, due to drying the coffee by means of wood fires, instead of by the usual sun method. This practise has been abandoned; Bahia coffee has shown a marked improvement in quality; and importations into the United States have increased. The Bahia coffee produced in the Chapada district is considered to be the best of the group. The bean is light-colored and of fair size. Other types are Caravella and Nazareth, both of which are below the standards demanded by the majority of the American trade.
