Well to me, "nice" would mean something a bit more expensive than the usual £5 a bottle from the supermarket! If you go to Oddbins they love showing off their knowledge, tell them how much you want to spend and they will help you choose something good.
Every year I buy my sister in law M&S vouchers, mainly because I have no idea what else to get her! This year, she has asked of a nice bottle of sauvignon blanc, (if that's how you spell it!). The thing is, I'm not a wine drinker, so have no idea what brand to get? Any ideas?
