In Genesis, what was Noah’s first recorded action after the Flood covenant?

In Genesis, Noah’s first recorded action after the Flood covenant was planting a vineyard. Genesis 9:20 introduces Noah as a man of the soil and says that he planted a vineyard after the covenant narrative.

The passage then describes Noah drinking wine, becoming drunk, and lying uncovered inside his tent. The episode leads to a family incident involving Ham and Noah’s sons, followed by Noah’s words about Canaan. These events belong to the post-Flood narrative and occur after the ark has been left behind.

Readers sometimes identify Noah’s first post-Flood action as building the altar, but Genesis places that earlier, immediately after he leaves the ark in Genesis 8:20. The vineyard is the first action specifically recorded after the covenant material in Genesis 9. It is also why Noah is associated in the text with both agriculture and viticulture.
