For his recent birthday party in his backyard, Karlsen had a mixologist on hand to make lemon and basil martinis alongside a tequila and champagne spritz for a fun pivot away from gin. A drinks trolley added to the party mood. The Tart girls have taken to making their own cordials, which get topped up with ice, soda and mint, or shaken with vodka and ice. Though Karlsen has fatigue of a particular variety: “Elderflower is done, I’m so bored of it!” he laughs, preferring a refreshing, homemade lemonade.
