If there’s one thing everybody should be able to do, it is to be able to mix one perfect drink. You can mess up your lasagna, only be able to run 50 metres before collapsing or be the dullest person in London, but if you can mix a drink you’ve got a true talent. On hand to help, London’s Revolution Bars provide cocktail masterclasses for individuals and groups. From £25 a head, you/your group will learn the tricks behind mixing, flaming, mashing and blending the perfect drink. Cheers.
