Consider what is being served with the main course and be careful that the salad dressing or sauce does not overpower the wine. Should the salad be the main choice of dish, Sauvignon Blanc is the most versitile. Here are some quick tips.
No dressing, mainly light, dry whites
Creamy dressings, look for richer white wines perhaps a Viognier or light oaked Chardonnay
Vinaigrette dressings, look for crisp, fresh whites
