Storybook Mountain Zinfandels are rarely, if ever, dramatic wines of exuberantly juicy fruit, but they are typically deep, and well-structured offerings that rely less on bombast and more on balance and varietal precision, and this one does just that. If slightly pulled back in ripeness and a tad tight just now, it has the right pieces in place to age handsomely, and, given its maker's track record for making long-lived Zins that reveal a certain claret-like elegance with time, we have no reservations about setting a few bottles aside for drinking when five or six years have passed.
