In Genesis, what was Noah doing when he became drunk after the Flood?

In Genesis, Noah was growing a vineyard when he became drunk after the Flood. Genesis 9:20–21 says that Noah, described as a man of the soil, planted a vineyard, drank its wine, and became drunk inside his tent.

This episode follows the covenant and the account of Noah’s sons. Ham saw his father’s nakedness, while Shem and Japheth covered Noah without looking at him. The story then reports Noah’s words about his sons and their descendants.

The passage is notable because Noah is presented both as the survivor of the Flood and as a farmer who begins ordinary post-Flood cultivation. The vineyard detail also connects the narrative with the ancient Near Eastern importance of grapes and wine.

The text does not say that Noah invented wine or that vineyards were absent before the Flood. It specifically says that he planted a vineyard after the waters had receded and then drank its wine.
