This year the London International Wine Fair celebrates its 30th birthday. For a number of years the event has been held at the ExCel centre in London’s docklands – a vast aircraft hanger of a place en route to Beckton deep in London’s once industrial East End. It’s a well organised event, and impressive in scale – the UK wine trade’s version of the Birmingham Motor show – but it’s also an alarmingly tricky place to taste wine. It must be something to do with the multitude distractions, the thousands of people or the weird lighting that makes it a tough job for even the finest wine to sing in this setting. That said there were a number that looked good on the first day here.
