Asking which wine to pair with salad is a bit like asking about what wine to match with meat or fish. There are so many different types, there’s no single answer. It depends on the vegetables you use, what other ingredients it contains or accompanies and, most importantly, what type of dressing it has.
Although not the problem they're generally made out to be tomatoes are one of the vegetables that do have an influence on a wine pairing. Being quite acidic, especially when dressed with a vinaigrette, you want a wine that has a good level of acid too - and not too much, if any, oak.
Tomatoes are generally held to be a problem for wine but as Jane McQuitty robustly puts it in The Times today - nonsense!
The last two days have been quite, quite beautiful, starting mistily, basking midday in an unseasonally warm sun and finishing with an extended dusk that announces that spring is finally here. I immediately want to eat lighter meals: the new season’s vegetables are not quite in yet but I can at least plan for summer and that means a spring clean of the cellar, pushing the full bodied reds to the back and assessing what whites, lighter reds and rosés I still have lurking in the racks.
