10-packs of Beck's Vier 44cl cans.
The on-pack promotion is aimed at boosting the brand's profile in the run -up to Christmas and giving consumers a better drinking experience.
Steve McAllister, commercial director for multiple off-trade, said: "We are offering shoppers something that will significantly enhance their enjoyment of the brand at home - and help to develop brand loyalty in the longer -term.
"The promotion delivers benefits for retailers in terms of incremental business during the important pre-Christmas sales period."
The glass features a square base, which is embossed to "enliven the beer during the pour to help the development of a good head", according to McAllister.
Consumers need to collect two tokens from separate 10-packs of Beck's Vier 44cl cans.
The promotion will be backed with in-store support in selected multiple retailers.
