The brewer dubbed Thursday 19 September ‘Young’s day’, when it celebrated its 188th birthday.
The new beers are ‘Head on’ Indian pale lager, a mix between a hoppy IPA and a crisp lager; and ‘Cityscape’, a “punchy” golden ale.
It has also launched a new brand identity for its beer operation, which focuses on the capital city and its residents’ “charge-on” attitude.
The branding also incorporates the company’s recognisable ram imagery.
Young’s chief executive Patrick Dardis said the launch would help set the brand apart from its competitors.
He said: “We are delighted to celebrate our 188th birthday.
“As an iconic pub operator that proudly serves at the heart of many local communities, we love exciting and delighting our customers with our premium offer and well-invested, differentiated pubs.”
The company now has more than 200 establishments across London and the south-east.
Dardis added: “We are thrilled by the launch of this new identity for our beer brand.
“It is part of our strategy of retaining our competitive edge and leading position in the sector by investing in the group, and ensuring we evolve to changing consumer demands and embrace the fast-paced vibrancy and dynamism of London.
“We think it will be an absolute eye-catcher at the bar.”
Young’s pubgoers could also claim a free pint of its beer on Thursday 19 September and Friday 20 September 2019 via its app.
