when did hops start being used in beer
Hops The first documented use of hops in beer is from the 9th century[citation needed], though Hildegard of Bingen, 300 years later, is often cited as the earliest documented source.[3] Before this period, brewers used gruit, composed of a wide variety of bitter herbs and flowers, including dandelion, burdock root, marigold, horehound (the old German name for horehound, Berghopfen, means "mountain hops"), ground ivy, and heather.[4] Early documents include mention of a hop garden in the will of Charlemagne's father, Pepin III.[5]
Airline DELAG, Deutsche Luftschiffahrts-Aktiengesellschaft was the world's first airline.[1] It was founded on November 16, 1909, with government assistance, and operated airships manufactured by The Zeppelin Corporation. Its headquarters were in Frankfurt. The first fixed wing scheduled air service was started on January 1, 1914, from St. Petersburg, Florida, to Tampa, Florida.[2] The four oldest non-dirigible airlines that still exist are Netherlands' KLM (1919),[3] Colombia's Avianca (1919),[4] Australia's Qantas (1921),[5] and the Czech Republic's Czech Airlines (1923).[6]
