You cannot leave town without sampling the favourite tipple of Venice’s workers. Invented when the city was under the rule of the Austrians, the Spritz comes in several different styles all guaranteed to leave you feeling funny in the ferry on the way home – half a glass of sparkling white wine, with a green olive and slice of lemon, is mixed with Campari for a ‘spritz al bitter’, with the faintly medicinal Aperol for a (surprise) ‘spritz al aperol’ or with a sweet liqueur for a ‘spritz al select’. Three glasses later and Venice definitely is the most beautiful city in the world.
