As white wine made its appearance at the villa very late this year, I bought a bottle of Spanish white last week from M&S. Despite being a behemoth of a store, the branch at London Colney had a very limited selection. So I plumped for the Cuatro Rayas 2007 Rueda, made from Verdejo for £5.39.

It transported me right back to Olivella. Grapefruit on the nose and lemon rind and gooseberries on the palate (like a new world Sauvignon Blanc without the grass) it was a fantastic partner to the oven-baked cod, basil and parmesan we had that night for dinner. I went back for more this afternoon, but they didn't have it at Muswell Hill! Drink it now people, if you can find it.

Still hankering for more white, I bought a New Zealand Sauvignon Blanc from Sainsburys later in the week. I hate to admit it, but I was seduced by the label. First of all it had a picture of a bird - a brightly coloured illustration of the love-child of a puffin, a parrot and a flamingo called the pukeko. Secondly, it had a "carboNZero" icon on the label - and I am a complete sucker for the environmental responsibility of food and wine (though this might seem like an oxymoron for a wine that comes all the way from NZ). So the Sanctuary 2008 Sauvignon Blanc from Marlborough couldn't fly into my shopping basket quicker.

I have a poor track record of selecting wines on the basis they have an attractive label. Thankfully on this occasion my selection criteria came good. It has lemon cheesecake on the nose and more lemon, ripe kiwi fruit and golden delicious on the palate. Mr DB and I drank it on Friday night, eating picnic food at Somerset House. Even out of a plastic bottle (no glass allowed, so the wine had to be decanted), chilled, it was the perfect partner to soft cheese, smoked salmon and Twiglets. I will be buying more.

As for its green credentials, I checked. The carboNZero programme is a international certification scheme to help businesses measure, monitor and reduce their carbon footprint. Yay! Now we can drink and help the planet. Just make sure you recycle the bottles.
