The national squabbling among states over when and how to allow direct shipment of wine between wineries and consumers is enough to drive a lawyer to drink.

The latest to step into the direct winery-to-consumer shipping debate is the 7th U.S. Circuit Court of Appeals. The court on Aug. 7 reinstated a requirement that Indiana consumers verify they are old enough to buy wine by filling out age verification forms in person at the winery (pdf) . It is known as the face-to-face clause in Indiana’s direct-shipping privileges law.
