Café HAG is a worldwide brand of decaffeinated coffee currently owned by JDE Peet's.
[1] Café HAG was founded in Bremen in 1906 as Kaffee-Handels-Aktiengesellschaft (Coffee Trading Limited).
The company's founder was Ludwig Roselius, who codeveloped the first commercial decaffeination process.
The Kellogg Company purchased Roselius's American branch (based in Cleveland, Ohio) in 1928,[4] then sold it to General Foods in 1939.
[1] Café HAG TV adverts were popular in the 1980s; in particular the character Klaus (played by Roger Callister) became something of a cult figure among advertisement aficionados.
