William H. Ukers, All About Coffee
“ Much the largest proportion of the wholesale coffee trade today is made up of roasted coffees, though some wholesalers still sell the green bean to retail distributers who do their own roasting. Most of the roasted coffee sold is ground; although in some parts of the United States there is at present a growing consumer demand for coffee in the bean. Of the coffee sold in trade-marked packages in 1919 in the United States, about seventy-five percent was ground ready for brewing. ”
