Sauvignon Blanc from Marlborough, New Zealand, is usually a crisp crowd-pleaser. But not only have some of the garden-variety bottles gotten insipid; the prices of the more famous ones have spun out of control. Have you seen how much Cloudy Bay is lately? (Over $20!) I’ve got two new go-to Marlborough SBs: Oyster Bay and Nobilo—both clean and citrusy, with lots of mineral taste in the Nobilo, and both available for under $12, sometimes even under $10.
