How many ounces of beer are in a log?

This is a trick question! There's no such thing as a "log" of beer.

Perhaps you're thinking of a "keg" of beer, which is a larger container. If so, the size of a keg varies, but a common size holds about 15.5 gallons, which is about 124 ounces.

Let me know if you had something else in mind! 🍻
