Kosher wine by John Spottiswood.

This is wine that's been made in accordance with Rabbinical law. Most people think of them as syrupy-sweet screw-top wines made with Concord grapes, but some kosher wines are now being produced that are indistinguishable from quality non-kosher wines. Unless pasteurized, a wine can only remain kosher if it's poured by an observant Jew. Bottles of pasteurized wine sport the label "mevushal."
