We have a root cellar and an inground cement springhouse with a trough along the wall full of cold flowing groundwater where we kept the full milk cans prior to trucking. When we stopped using milk cans it kept our beer cold.
We used to joke that you sobered up every time you reached down in the cold water to grab another beer.
When I was a GI in Korea, we played a game called bobbing for beers. Like bobbing for apples except with a garbage can full of ice water and cans of beer. Stop your heart.
