Q How has winemaking changed since your family acquired Krug in 1943?
A We used 6,000- to 9,000-gallon redwood tanks, brass fittings, and glass transfer lines. We didn’t have refrigeration. To cool the fermenting wines, we’d throw blocks of ice in a coolingtower. Today, almost everything is stainless steel.
Q Wine prices back then?
A We recently found a 1949 wine list from Antoine’s Restaurant in New Orleans. Every bottle, including several from Charles Krug, cost just $2.
Q What’s new at Krug?
A We just started barrel tastings for groups of eight on Fridays and Saturdays. For this year’s Tastings on the Lawn—our 60th, on September 10—we’ll likely dig into my personal library for a rare wine. In 2010, we opened a 1974 cabernet.
Q What’s the best wine grape?
A Cabernet sauvignon is king. The flavors are complex and the wine develops different characters as it ages. Our 1957 vintage is a real winner—that was 100 percent cabernet. There’s one bottle of the 1944 left in the wine library.
Q You still drink wine?
A A glass a day. I can’t think of any better beverage for meals.
