There are 14 beers in a Heineken mini keg. The Heineken mini keg contains 5 liters of beer, which is equivalent to 169 ounces. A can of beer contains 12 ounces, and 169 ounces divided by 12 ounces per can equals just over 14 cans of beer.
On a per-beer basis, the Heineken mini keg is cheaper than buying canned or bottled beers. The manufacturer saves on packaging costs and passes on savings to the consumer.
In addition to saving money, the consumer who chooses a Heineken mini keg instead of cans or bottles is also helping the environment. The amount of wasted packaging associated with mini kegs is less than that associated with other types of packaging.
