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.
It’s easy to get stuck in the trap of thinking red wine is the only accompaniment for meat, especially red meat but in these days of multi-cultural eating that’s not necessarily true. And a good case in point is a Thai beef salad with its zingy, hot/sour flavours which influence the match much more than the beef does.
