Washington: Twitter has introduced an age-screening system that the micro blogging site said will help alcohol brands `safely grow their of age network`.
Users of Twitter.com and its iOS and Android apps trying to follow specific brands will receive a direct message that will direct them to an age gate and gives them 24 hours to provide the relevant information. According to the Verge, the first partners include Jim Beam, Knob Creek and Bacardi .

As the users fill in their birthdays, Twitter cross-checks them against the drinking age limits, and either revokes access or allows the follow request, the report said.
Twitter said it `may identify the number of users within an age range that follow a specific account or types of accounts,` it added.
