There is no Crane Lake Cellars. It is just a "marketing name". The actual Winery is the Bronco Wine Company, owned by Fred T., Joseph S. and John Franzia Jr. and ranked fourth largest U.S. Wine Company.
Give me a sec to get you a few links.

There are two other "Crane" wineries. "Crane Family" and "Crane Canyon", but they are independant wineries and have no connection to Crane Lake Cellars. (as far as I know).
You can give Bronco Wine Company a call and check - they have a toll-free number. and should be able to tell you a distributor.
