It’s all about dark, bitter or savoury cocktails these days – using ingredients such as Kamm & Sons (ginseng liqueur), Becherovka (herbal liqueur), Campari, Aperol (bitter rhubarb liqueur), Kümmel (made with caraway and cumin), absinthe and even tobacco-infused liqueur. Try the excellent new House of Tippler in East Dulwich, Barts in Chelsea, and Nightjar, where they hand-smoke their booze. If you can wangle your way into Little House, Soho House’s latest club, order a scorched pisco sour with smoked absinthe spritzed over the top.
