Scharffenberger in Boston ?
As a former Westerner living out here, it never ceases to amaze me how light Boston is on CA wines as compared to bottles from France and Italy. Having said this:
Not positive, but I believe I've seen it at Federal Wine. Certainly worth calling them, as well as Brix, and the Wine Bottega in the North End. If they don't have it, they'll certainly be able to order it for you.
