There are three days in the calendar that I block out every year, as soon as the dates have been announced. Pity the fool who has a birthday or a wedding during that time (luckily, none of my friends have a birthday around then, and I can always vet any new ones I might make; weddings are trickier, but so far, so good). Frankly, there is not much that will get in the way of immersing myself in enough wine to fill Olympia London – which is precisely the opportunity that the London Wine Fair brings.
