It is now the basis of a booming new industry that draws on that tradition with modern twists. This talk will explore the history of cider in Maine from settlement through the temperance movement of the nineteenth century and beyond to examine its virtual disappearance in the state as a commercial enterprise in the twentieth century. Interestingly, the decline of cider in the twentieth century may have very little to do with Prohibition. Come learn what makes heirloom apples so great for making cider, and why you would not want to eat some cider varieties. Presented by Todd Little-Siebold. $20; $15 MOFGA members. Registration.
