Twitter has launched a new age verification screening process for alcohol brands on the website.

Brands such as Heineken and Jim Beam have rolled out the age verification process.

When someone requests to ‘follow’ one of the alcohol brands, it will automatically send the user a direct message, directing them to the age verification page. It will then give you 24 hours to supply your age. If you are unable to do so, you will not be able to follow the brand.

Other brands that require an age verification include Barcardi and Bud Light.

On a Twitter blog post, a spokesperson said, "Our hope is that this approach to age-screening will enable alcohol brands to responsibly and safely connect with the right audience on Twitter."

Although underage users cannot follow the brand, they are still able to see the news feed content, so what difference does this screening make? Will it really prevent underage people drinking the alcohol or admiring the brand?
