People who pick up a bottle of Whitesnake Zinfandel probably have little doubt that rock singer David Coverdale has something to do with the De La Montanya winery-produced red. Why else would it bear the name of Coverdale's long-lived heavy metal band, which topped the charts in 1989 with songs such as "Is This Love?" and "Here I Go Again"? The Britain-born musician's love for wine stretches back to the mid-'70s and his days as the lead singer of seminal hard rock band Deep Purple. Coverdale, no less a rocker at 59, spoke from his home in Lake Tahoe to freelance writer Robert Simonson about his favorite bottles and the unexpected success of the wine Coverdale describes as "a bodacious, cheeky little wine, filled to the brim with the spicy essence of sexy, slippery Snakiness." Wine Spectator associate editor Robert Taylor explains.
