Muscadet is great with all sorts of shellfish. It's no coincidence that the region is as famous for it's seafood as it's wine.
Loire Sauvignon is wonderful with a seafood platter or scallops.
With fuller flavours, lobster or a rich sauce, try an intense oak-aged wine, or even a slightly chilled Loire red.
For a change take a well chilled crisp dry rose.This can be delightfully refreshing on a warm summer's day
