This GLOSSARY OF FOOD TERMS by CUESA (Center for Urban Education about Sustainable Agriculture and organizer of the San Francisco Ferry Building’s Farmers Markets) is one document you should save for future reference. From Artisanal and Biodynamic to Transitional and Vine or Tree-Ripened, the labels on our foods, grocery shelves and farm stands are demystified. (Biodynamic chard, left)
