The increase applies to Guinness Draught products, including Guinness Draught in keg, microdraught and Guinness Surger, effective from Thursday 1 May 2025.
Guinness 0.0 and Guinness Draught in can format will not be impacted by the price hike, Diageo confirmed.
A Diageo spokesperson said: “We have today informed our on-trade customers of a Cost Price Increase (CPI) on Guinness Draught products.
Sustain investment
“Guinness is a high-quality beer that is a significant footfall generator for hospitality, and this CPI ensures we can sustain investment levels in, and continue to grow, the Guinness brand.”
The beverage company added it does not set the retail price of a pint in pubs.
Citing data from CGA, Diageo claimed the average cost of a pint of Guinness in the on-trade was 16% lower than that of world premium lagers, coming in at £4.62 vs £5.45.
Alongside the price increase, Diageo also committed to providing 1m Guinness glasses to support on-trade customers over the next 12-months, 500k of which are set to be suppled over the next three months.
Replenishing stock levels
The brand has faced supply issues since December 2024, with a spike in demand having caused issues for some operators over Christmas. One pub in London introduced Guinness ‘ration cards’ to manage supply shortages.
However, Diageo assured while demand has continued to grow, supply issues have been tackled.
The spokesperson added: “While demand for Guinness continues to grow, we have made progress in replenishing stock levels in Great Britain so that supply has returned to more normal levels.
“We will continue to manage supply responsibly so that consumers can look forward to enjoying high-quality pints through the spring and summer.”
Diageo added it was in “constant conversation” with customers, who would be the “first to know” of any changes to supply plans.
