The blessing over the meal is immediately followed by another blessing over the wine:

בָּרוּךְ אַתָּה יְיָ, אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם, בּוֹרֵא פְּרִי הַגָּפֶן

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

We praise God, Spirit of Everything, who creates the fruit of the vine.
