Nervous Nellies Jams and Jellies produces its products on-site in its jelly kitchen almost daily.  From May through October the Mountainville Cafe serves up coffee, tea and homemade scones with plenty of delicious jams, jellies , conserves and preserves.  Leave some time when you visit to stroll the grounds and enjoy the found object art sculptures created by Peter Beerits.   The displays are full size so you can enter a castle complete with knights in shining armor and a honky-tonk piano bar among other whimsical offerings.  Gift items in the Cafe are made by Maine artisans such as Maine Float-Rope Co. doormats; oil-cloth bags made in Calais and birdhouses crafted in Falmouth.
