Twitter introduced a screening-age feature for alcohol brands using the social network. Mashable reports that if you plan to follow Heineken on Twitter, you will get a direct message linking you to the age verification page. You will be given 24 hours to state your age and if you meet the requirement, you can then follow the brand. Other partners Twitter has for this feature include Bud Light, Bacardi, Jim Beam, and Knob Creek. The feature works on the web as well as Android and iOS apps.
