How wines age under twist-offs

Twist-offs, aka screwcaps, prevent wines from suffering cork taint. But Harry Peterson-Nedry believes that’s only one advantage. “In 20 or 30 years we’re going to say that other benefits are even bigger,” he says. We were pouring 10 vintages of his Chehalem Pinot Noir Willamette Valley Three Vineyard Pinot Noir to see how well they have aged. No suspense, every single bottle was free of any kind of taint, and the older vintages, back to 2004, had developed extra layers of aromatics and flavors that come with time in the bottle.
