The weather in London is looking a bit more Sauvignon Blanc-friendly than it has been recently, but this isn't a bracingly sharp, cold-shower kind of Sauvignon anyway. It's certainly not short on zing and vibrancy, but ageing the newly fermented wine on its lees (yeasty residues) has added a delicate creaminess to the juicy white peach, apricot and grassy pea-shoot flavours. It's only then that the palate dives headlong into a zesty grapefruit finish. I can’t recommend it with haggis, but it makes a reviving aperitif, and a good partner for shellfish and other fish, including with spices, and for goat's cheese, red peppers, tomatoes, aubergines and leafy salads. A bit of pub-quiz background: De Grendel, about 20km east north-east of Cape Town, is one of its oldest farms, with cattle, sheep, horses and blueberries as well as wine; it was bought in 1890 by the De Villiers Graaff family who still own and run it, headed now by Sir De Villiers Graaff, 4th Baronet.
