Name: School House Farm
Location: Warren, ME, on the landward side of Rte 1
Specialties: Heirloom apples, some other interesting produce, fresh unpasteurized cider, honey
School House Farm is on Route 1 not very far beyond Moody's Diner in Waldoboro and Morse's Sauerkraut. I like to buy cider there, and they always have a good range of apples, including Northern Spy and Red Gravenstein (pictured).
I don't think they have a website, but they are mentioned in several Maine websites of interest to foodies.
