Grand Vin is French for great wine, and on a label it means the estate's flagship bottling - not a legal classification, and not the same thing as Grand Cru. Where the idea comes from in Bordeaux, what it does not tell you, and the Domaine du Castel ladder from $29.99 to $112.99 as a worked example.

Lychee turns up on our shelf in four completely different bottles - an Italian sparkling moscato in a can at $16.99, a Japanese sake at $15.99, a sweet Israeli fruit wine at $24.99, and an aniseed arak at $26.99. What each one tastes like, how sweet it really is, and which one belongs on your table.

There is no grape, region or style called Jewish wine. What people usually mean is kosher wine - or the sweet purple Concord bottle from the seder table. Where the sweet stuff came from, what actually makes a wine kosher, and what to drink whether you want dry or sweet.
