Your understanding of chocolate production may be limited (no, bonbons don’t grow on trees).

But that doesn’t stop you from labeling it a major food group.

Luckily, this week, Alejandro Luna opens his charming neighborhood chocolaterie, Aroa Fine Chocolate, where the finer points of the production process are fully uncovered.

Using only the best fair trade, single-bean chocolate from Venezuela, Luna crafts individual European-style desserts, seven (yes, seven) luscious variations on hot chocolate, nougats, macaroons, and a dazzling slew of chocolate bonbons. Between the open-view kitchen and a life-of-chocolate photo gallery, Luna will ensure you know everything about chocolate.

Check out one of the regular tastings or classes to satisfy whatever curiosities your palate may have.

And to ensure you maintain a sensible diet.

Aroa Fine Chocolate, 1651 Washington Street, South End (617-425-4988).
