Kosher wine (
Hebrew: יין כשר,
yayin kashér) is
grape wine produced according to
Judaism's
religious law, specifically,
Jewish dietary laws(
kashrut).
Almost all
Jewish holidays, especially the
Passover Seder where all present drink four cups of wine, on
Purim for the festive meal, and on the
Shabbat require obligatory blessings (
Kiddush) over filled cups of kosher wine that are then drunk.
Grape juice is also suitable on these occasions. If no wine or grape juice is present on Shabbat, the blessing over
challah suffices. At
Jewish marriages,
circumcisions, and at
Redemption of First-born ceremonies, the obligatory blessing of
Borei Pri HaGafen ("Blessed are you O Lord, Who created the fruit of the vine") is almost always recited over kosher wine (or grape
juice).
According to the teachings of the
Midrash, the forbidden fruit that
Eve ate and which she gave to
Adam was the
grape from which wine is derived, though others contest this and say that it was in fact a
fig.
[5][6] The capacity of wine to cause
drunkenness with its consequent loosening of inhibitions is described by the ancient rabbis in
Hebrew as
nichnas yayin, yatza sod ("wine enters, [and one's personal] secret
exit"), similar to the Latin "in vino veritas". Another similarly evocative expression relating to wine is: Ein Simcha Ela BeBasar Veyayin—"There is no joy except through [eating] meat and [drinking] wine".)
