Today we decided to drink coffee in the special exhibition of the German Museum, founded by Oskar von Miller, the famous engineer, in 1905. It was finally opened in 1925 and is now the largest science and technology museum in the entire world. Prices have gone up since I last visited, an adult pays €14, so be sure to bring along plenty of time.
The “Cosmos Coffee”, on the second floor passing through the Physics department, runs through May 2020. There are many exhibitions on at the same time, also plenty of demonstrations and guided tours which are free of extra charge.
Our tour guide lived in Venezuela for many years and was very competent. She showed us the plants, the coffee flowers of the more delicate plants, the “talking drawers” with old slogans and clichés, the “smelling machines”, the coffee room, the roasting machines, the different bean colors depending on the roasting temperature.
One cup of coffee requires 140 liters of water to let the plants grow and mature, about 5-7 years. The plant came originally from Ethiopia where it is said the goats ate the berries and capered around more than usual. To the human palate the berries were too acid and hard, so they were tossed into the fire – where they developed a fantastic chocolatey aroma. From Africa, coffee made its way to Al Mokha, Yemen and to Istanbul, Turkey, and from there to many others, reaching the US in the 17th and Russia in the 18th century.
The special roast “Cosmos Coffee” at the Museum is 80% Robusta and 20% Arabica. At the bar you can order from a large menu of 8 roasts and 6 kinds of preparing. The espresso was too strong, but the cappucino was delicious and the young barista makes the best hearts and swirls into the milky froth. You can stand at the tall tables or sit down on the benches and relax with a Florentine biscuit.
