Vienna's coffeehouse culture is so central to city identity that UNESCO has formally listed it as intangible cultural heritage — one of the only times a way of drinking coffee has earned that status.
A Wiener Melange is roughly half strong coffee and half hot milk, topped with a layer of milk foam, traditionally served on a small tray with a glass of water. It's meant to be lingered over for hours in a Kaffeehaus, not rushed.
