I make no apologies for being a sherry fan. In fact it amazes me that it's still so unpopular and still so underpriced.
This classic style from Bodegas Barbadillo is a real treat. Ultra dry, nutty and ever so slightly salty, it's designed to be drunk well chilled with tapas such as nuts, olives and slices of chorizo (Tesco has a good one which works well in cooking too). It's also really good with fried fish.
This is the first of a weekly slot where I'll highlight a wine I think offers good value for money. At £5.49 a 50cl bottle (£5.21 a bottle if you buy a case online) - enough for 5-6 glasses - this is bang on the mark.
Available in 286 (i.e. larger) Tesco stores.
