Since its launch in 2013, Coravin has sold 70,000 devices, which use a thin needle and inert gas to extract a wine sample without needing to uncork the bottle. Having arrived in the UK last year, many restaurateurs and merchants, including D&D London, Le Gavroche and Lea & Sandeman, have embraced the opportunity this technology offers to serve accessibly priced fine wines by the glass without risk of wastage.
