How many cans in a half rack of beer?

A "half rack" of beer is not a standard unit of measurement. The number of cans in a half rack will depend on the specific size of the cans and the arrangement of the cans in the rack.

Here are some possibilities:

* 12-pack: Some stores may refer to a 12-pack as a "half rack," especially if they also sell a "full rack" (which would be a 24-pack).

* 18-pack: In some areas, a "half rack" could be an 18-pack of beer.

* Other arrangements: The term "half rack" might also be used to describe a specific configuration of cans in a retail display that holds a different number of cans.

To know for sure how many cans are in a "half rack" of beer, you'll need to ask the retailer or check the packaging.
