One of The Earliest Colonial Buildings Was a Brew House
One of the first American colonies in Jamestown, Virginia was founded in 1607 by a group seeking "a sober lifestyle and a healthy diet".
It failed.
Miserably.
Colonists gave themselves salt water poisoning and died of starvation. Jamestown's failures was one reason why the Plymouth colonists, upon setting up camp in Nov. 1620, made it a priority to build a brewhouse. A tavern followed soon after.
The inaugural Thanksgiving, held in the fall of 1621, featured beer made using the settlers’ first barley crop.
These two historical moments (a well-founded suspicion of water and a cultural life built around the tavern) will go on to impact American drinking to this very day.
These are just some of the reasons why drinking in America is deeply woven into social etiquette, and why the non-drinker is frequently viewed with suspicion.
