A vine. . . though only moderately fruitful should be our choice, if only we have a piece of ground where the flavor of the wine is distinguished and costly; for if it is of poor quality or low in price it is best toof poor quality or low in price, it is best to plant the most prolific vines so that our revenue can be increased by the greaterrevenue can be increased by the greater quantity of the yield.” Columella 50 A.D.

• Geographic Indicators give groups of firms the Geog ap c d cato s g e g oups o s t eopportunity to differentiate themselves.
• It is unlikely that wines from one G.I will possess y punique flavor profiles.
• It is unlikely that G.I.s are better indicators of what a wine will taste like than are brand and varietal labels (or price).Th lif ti f G I i f i t t t• The proliferation of G.I.s is of interest to some consumers and is confusing and intimidating to othersothers.
