Jewish celebrations usually include wine as a symbol of joy.

Wine sanctifies an occasion and makes it holy.

During the Passover Seder we drink four cups of wine, why four?

In the Book of Exodus, God convinced the Jews to leave Egypt using four statements:

I shall take you out
I shall rescue you
I shall redeem you
I shall bring you

We toast each of these statements with a cup of wine.

Pour and raise your first cup of wine/grape juice. This cup is dedicated to the renewal of spring, to the renewal of ourselves.

בָּרוּךְ אַתָּה יְיָ, אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, בּוֹרֵא פְּרִי הַגָּפֶן

Baruch Atah Adonai, Eloheinu Melech ha-olam, borei p’ree hagafen.

Praised are You, Lord our God, Whose presence fills the universe, who creates the fruit of the vine.
