Not sure,best to contact winery direct,sorry.
You can request your local wine shop to bring in a case
I've not shipped to Massachusetts but I have tried to ship to New York and you have to go through a distributor so they only get it when I visit and pack it in my suitcase. Sorry I couldn't give you a more definitive answer.
Call them about joining their wine club or case club. Depends on Massachusetts laws, but you could get it shipped to you. Try the Reisling Special Harvest. It's the best! If you can it's an awesome winery to visit!
