B.F. Clyde's Cider Mill
129 N Stonington Rd
Old Mystic, CT 06355
The oldest steam powered cider mill in the US. plus they sell their own hard ciders most are more apple wines than cider (and high octane to boot)... so go on a weekday/saturday, so you can buy some to enjoy while you make your own.
Also
Beardsley's Cider Mill
278 Leavenworth Road,
Shelton, CT 06484
They will even fill up your carboy, barrel or brew bucket directly with fresh unpasteurized cider. Plus they have the best apple donuts in the world!
Enjoy!
