My wife and I throw a party every Memorial Day weekend. We supply our guests with choices of soft and alcoholic beverages, including beer. During party planning, each year my wife and I discuss whether to buy cases of canned beer or a keg. The perception is that getting a keg is similar to buying in bulk, so it should be cheaper. But is keg or canned beer cheaper?
I decided to break down the math and compare the cost of a keg of domestic light beer to buying the same amount of beer in cans. The answer has changed over the years, and the math is not quite as simple as comparing the sticker price on a keg to the price of a case of beer.
