John 2:6–11
The first sign
6 Now there were set there six waterpots of stone, according to the manner of the purifying of the Jews, containing two or three measures apiece.
7 Jesus saith to them: Fill the waterpots with water. And they filled them up to the brim.
8 And Jesus saith to them: Draw out now and carry to the chief steward of the feast. And they carried it.
9 And when the chief steward had tasted the water made wine and knew not whence it was, but the waiters knew who had drawn the water: the chief steward calleth the bridegroom,
10 And saith to him: Every man at first setteth forth good wine, and when men have well drunk, then that which is worse. But thou hast kept the good wine until now.
11 This beginning of miracles did Jesus in Cana of Galilee and manifested his glory. And his disciples believed in him.

Why this matters
Jesus changes water into wine, manifests his glory, and his disciples believe in him. These verses provide the outcome of the Cana narrative; they primarily describe Jesus’ action, rather than directly praising Mary.
