Diageo has confirmed its adding 7 cent to the price of a pint of its draught products from next month.
The company's also adding 10 cent to the cost of a pint of Guinness 0.0.
Diageo says industry wide cost pressures continue to exist and it must ensure it can maintain sustainable operations.
The Vintners' Federation of Ireland says many pubs simply won't have any option but to pass this increase on to customers.
A spokesperson for Diageo says: "Industry-wide cost pressures remain elevated for businesses, and in order for Diageo to maintain sustainable operations in Ireland, we have advised our on-trade customers that there will be an increase to the list prices on our full draught product range.
"This includes an increase equivalent of €0.07c per pint of Guinness, and €0.10c per pint of Guinness 0.0 and will take effect from 2nd February 2026."
CEO of the Vintners Federation of Ireland Pat Crotty says: "Publicans are being hit from all sides, but drink costs are the biggest burden they face. This latest price increase from Diageo will put even more pressure on pubs that are already operating on extremely tight margins.
"Many will be left with no option but to pass this on to customers, which helps nobody.”
"Our members understand that suppliers also face rising costs, but there comes a point where pubs simply cannot keep carrying these increases alone. Pubs are at the heart of local communities and suppliers depend on them for their route to market.
"We expect suppliers, including Diageo, to recognise that reality and to support VFI members rather than repeatedly adding to their cost base."
