We like a lot of Sauvignon Blanc here at Camp Borepatch, and so I picked up a bottle at Trader Joe's absurdly low $4.49 list price. This will be making an appearance in the wine cellar here. This review doesn't do this justice, giving it only 85 points out of 100. However, this is a crazy good price/performance ratio, and so while a New Zealand Marlborough Sauvignon will indeed be better, you will pay two and a half times as much. This review is more in like with my thinking (although perhaps a little generous), but as with all reviews, your mileage may vary.
For daily white vin de table drinking, this has migrated pretty high up on my wine list.
