(Decanter) - Fine wine buyers in the US, Asia and also Europe have wasted little time in seeking to take advantage of the weak pound sterling currency following the UK's vote to leave the European Union, according to the country's merchants. Growing numbers of the UK’s fine wine merchants are reporting a post-Brexit boost in demand, but they are also wary that the cost of replenishing their cellars with top wines from Europe could be significantly more expensive. Where is the demand coming from? It is predominantly fine wine lovers and also merchants overseas who are looking to capitalise on a sterling currency that has hit a 31-year low following the Brexit vote. ‘We’ve had fantastic sales since Brexit became a reality and the pound plummeted,’ Stephen Browett, of Farr Vintners, told Andrew Jefford earlier this week. Most of the wine has gone to Hong Kong buyers, he said. ‘But we’ll have to replace that wine, and because the pound has fallen about 10 per cent against the euro, prices will have to rise by about that much.’ Liv-ex, the fine wine trading platform, has already reported stronger demand from the US in the immediate aftermath of the UK’s EU referendum result. It reported that its key fine wine indices continued to recover in June, following several years of weakness.
