Guinness Foreign Extra Stout Guinness Foreign Extra Stout (FES) is a stout produced by the Guinness Brewery, an Irish brewing company owned by Diageo, a drinks multinational. First brewed by Guinness in 1801, FES was designed for export, and is more heavily hopped than Guinness Draught and Extra Stout, and typically has a higher alcohol content (at around 7.5% ABV), which gives it a more bitter taste. The extra hops were intended as a natural preservative for the long journeys the beer would take by ship.
