Mosiah 11:15

And it came to pass that he planted vineyards round about in the land; and he built wine presses, and made wine in abundance; and therefore he became a wine bibber, and also his people.

He planted grape fields all around the land. He built places to make wine and made lots of wine. So he and his people became drunk a lot.

He planted vineyards all over the land, built wine presses, and produced wine by the barrel. He became a drunk. So did his people.
