Shimmering brilliance and seamless layers of flavour – beautifully expressive Sauvignon from a vineyard less than eight miles from the Pacific Ocean. Maybe it’s auto-suggestion but I find a sea-salty tang beneath the vibrant citrus, greengage and smoky, flinty flavours. Errazuriz’s more everyday Sauvignons are reliably good value, but this is more than the equal of a good Sancerre or Pouilly-Fumé – and great value at the current offer price. It’s not in all stores but Waitrose's entire range is available online. Try it with shellfish, white fish, mild Vietnamese or Thai curries, vegetable dishes, or on its own as a reviving aperitif.
