A Beet Story
The beets that prompted this story grabbed my attention because they had been bred with flavor in mind. Specifically, these beets had been selected to be either very high or very low in geosmin, the simple twelve-carbon molecule that gives soil its distinctive earthy aroma. It’s long been known that beets have an earthy character; some people call them “dirt candy” while others say they just taste like dirt. Of the flavor components identified in beets, earthiness is the one that people most often dislike, so my doctoral advisor, Dr. Irwin Goldman, had wondered: If we bred a beet with less geosmin, would more people like it?
