This is a great value for money New Zealand Sauvignon Blanc from the Marlborough region, renowned for excellent sauv blanc wines.
You can find Oyster Bay almost anywhere and it's often in the big supermarkets for less than $15. Wine.com has it online currently for $13.99, which isn't a bad price.
As always, the rule of thumb with Sauvignon Blanc is DYA (drink youngest available) and so this 2013 is drinking very nicely now. It's is super crisp and clean on the palate and quite zesty. It goes very well with fish or salad and especially well with oysters.
