New Zealand is starting to produce some interesting non-Sauvignon Blanc choices, and as I was making some tuna with lime I picked up a Spy Mountain Marlborough 2007 Riesling from Tesco.
Pale lemon green, it smelled lightly of petrol and citrus. It was off-dry with a medium body and a medium alcohol level. It had a zippy, limey acidity. The citrus flavour was soften by honey and a hint of peaches.
It was a tasty choice to match the fish.
