Ester of Wood Rosin

Last night, I picked up my bottle of Fresca and did something ill-advised: I read the list of ingredients. “Carob bean gum” I expected. “Brominated vegetable oil” was somewhat disturbing, conjuring up images of the soda used in some sort of a stir fry. But the ingredient that really caught my eye was “Ester of Wood Rosin.” Ester of Wood Rosin sounds to me like some kind of mix between a Celtic fairy tale and the sequel to Anne of Green Gables. Or perhaps the title of a participant in the Society for Creative Anachronism. Get thee to a smithy, Ester of Wood Rosin!
