It's summer and we enjoy the many long, mild evenings on which we celebrate the otherwise un-Teutonian aperitif culture. We like to have a sparkling drop in our glass with Mediterranean finger food. Rosé, Aperol Spritz and white wine spritzer always work. But it can also be a little more high-percentage. Do you already know the Portonic, for example? Or how about a gin-seng tonic?
