A Draftmark refill is a gallon container of beer that fits into the company's draught system, which sits in the customer's refrigerator. This system allows the user to pour only the desired amount of beer for each serving. Oxygen does not contact the beer until it is poured.
The Draftmark system keeps beer fresh for 30 days after the refill is first tapped. Refills include lagers and ales. Though the type of beer available to a customer varies by geographic location, some common brands are Budweiser, Shock Top, Goose Island, Michelob and Bass. Draftmark's website has a Find Us page, so interested consumers can search for nearby stores.
