I have had a couple of OK British wines. But, of course, as documented elsewhere, I'm not a wine snob and generally, when I drink vino, it's Chateau Sainsbury's out of a box (because it's cheaper than the boxes they sell in Waitrose). If I'm drinking out of a bottle, it must be Christmas. Using a glass just generates more washing up.
In other news, I've been to the Trump winery.
