A guide to finding the best wines and where to buy them from.
I sought wine advice from the guardian's wine critic, who runs a site called Superplonk.com. Here you can search over his reviews of wines for the top rated wine of the type you want.
I was researching sparkling wines and champagnes for my wedding, and bookmarked this search which lists his top rated sparkling wines and champagnes under £30. I did some searching to find the top rated wines locally, but found that only Majestic wine stocked the wine (Cloudy Bay Pelorus), and I would need to buy at least 12 bottles of wine. Not being a big wine drinker I ordered two test bottles from Wine and co.com, after enjoying them I went ahead and bought 18 bottles for the big day.
For a red-loving Spanish friend I looked for the best red from his home country (the best Spanish Reds under £10), found some well priced wines at Waitrose, who have a branch locally and bought them there.
