"Cathy Corison's Cover Crop Corison Winery is a must-visit anytime of the year — the hospitality is friendly, honest and open, reminiscent of 20 years ago, which is about when Cathy started making wine in Napa Valley . The tasting room is in the winery (Cathy is usually around checking barrels or pouring wine) and there are almost always older vintages to explore — Cathy once compared her decades of age-worthy wines to a string of blinking Christmas lights — one may be brighter one moment, another the next. One of the best times to taste through the wines from the estate's Kronos vineyard is during the winter when you can see the old vines in all their gnarly beauty (Cathy replants one vine at a time as they get too old or sick to produce) and the impressive mustard seed is ablaze beneath the Mayacamas mountain range.
