Wizards of every stripe will descend on Chestnut Hill Oct. 21-22 for the Harry Potter Festival, turning it into a cross between Diagon Alley and Hogsmeade. Here’s some of what the Co-op has in store for Potter Nation.

Reed’s Flying Cauldron Butterscotch Beer— Every sip will make you a better wizard. Non-alcoholic and free of caffeine, gluten and GMO’s.

Marich Green Beans Jelly Beans — In bulk in a rainbow of colors. Sorry — no vomit, earwax or tripe flavors. (Note: Sunny Harvest Jelly Beans also available in bulk in Mt. Airy.)

Fire Whisk — er, Fireside Tonic — Food & Ferments of Truxton, NY, makes this version of the peppy potion cure-all. Suited to grownup tastes. Available Next Door and Across the Way.

Chocolate— Any of your favorites will help in case of Dementor attack., but we hear fair trade chocolate is an especially strong antidote.
