The University was later moved to company offices in Trieste; the Unicaffe network currently has 27 branches worldwide. Company Illycaffè S.p.A. markets coffee-related products in approximately 140 countries worldwide. The Illy Group is made up of several companies located in North America, France, Germany, Spain and Benelux. The group employs approximately 800 people in these locations. Since the end of the 1980s, illy has purchased its green (raw) coffee beans directly from source countries, rather than the international commodities markets. The company exclusively purchases coffee of the arabica species, in particular from Brazil, the largest producer worldwide, but also from Colombia, India, and countries in Africa and Central America. Illy's Università del caffè ("University of Coffee") offers free training for growers. In Brazil, a nine-month program (one week per month) includes 360 hours of lectures. Illy buys between 10% and 30% of coffee produced by growers trained at the University of Coffee at a premium price, but does not require that the growers enter into an exclusive contract with the company. Illy was the world's first company to receive the Responsible Supply Chain Process (RSCP) certification of sustainability awarded by the Det Norske Veritas (DNV). From 2004 to 2012, illycaffè funded the Ernesto Illy Trieste Science Prize to recognize scientific researchers from the developing world, in collaboration with The World Academy of Sciences (TWAS). Illy was featured in the 2006 documentary Black Gold, in reference to its marketing of coffee from Ethiopia. In an interview with The Wall Street Journal in June 2021, chairman Andrea Illy expressed interest in expanding the company's presence in the United States, the largest coffee market in the world. He noted branding as one of the main focuses in breaking into the market, as well as strengthening the company's distribution network both online and in larger retailers such as hotels, restaurants, and cafes. Coffee and energy drinks Illy coffees are blended from arabica beans from multiple sources. The grounds are packaged in steel canisters and pressurized with an inert gas rather than air. On 22 May 2009, in partnership with The Coca-Cola Company, illy launched a line of coffee-flavoured energy drinks marketed as illy issimo. In 2009, AirTran Airways began serving the beverage to passengers, which has since been available in five flavors: caffè, caffè no sugar, cappuccino, latte macchiato, and mochaccino.
