The Chancellor intends to add 2p to the price of a pint, delivering a fresh setback for drinkers.
John Healey is expected to unveil a hike in alcohol duty during his first Budget tomorrow, even though pub chains and trade groups have asked for a tax freeze.
Alcohol duty is a levy applied to the manufacture, distribution or import of drinks containing more than 1.2% alcohol.
Under the proposal, the duty on each pint sold would increase in step with the Retail Price Index, currently at 3.9%, according to The Telegraph.
At that pace, the tax rise would lift the cost of a pint from 50p to 52p.
The change could add between 10p and 12p to a bottle of wine, depending on its strength.
A 37.5% gin bottle could see a rise of 35p.
The announcement follows former Chancellor Rachel Reeves' decision last year to tie alcohol duty to inflation in the Budget.
Duty rose by 3.66% in February, adding 6p per four-pack of lager.
A typical wine bottle experienced a 13p increase, while prosecco went up by 11p.
The Sun's Save Our Sups campaign seeks to keep British pubs, clubs and live-music venues open.
Official figures show the Government collected £12.44billion in alcohol duty for the 2025/26 fiscal year.
Approximately £2.58billion came from wine and fermented products.
Beer contributed about £2.09billion.
The Treasury was contacted for comment.
