The price of some of the most popular pints in Ireland is set to soar next month after Dutch beer company Heineken wrote to Irish pubs to inform them of a significant price hike in the price of kegs.

Heineken wrote to Irish publicans on Thursday, November 10 to inform them of "a price increase on all our draught products" which will come into effect on December 1.

Keg prices for Heineken and Coors lager will increase, equivalent to 17c per pint, Heineken said in its letter.

The increase "is essential for us to offset, in part, the severe input cost pressure," Heineken said, noting the "unprecedented cost increases across the entire supply chain". 

The Dutch beer company separately told the Irish Independent that it had "no choice" but to increase its prices due to "significant" increases in the cost of energy, packaging, and raw materials. 

The price of a 50-liter keg of Heineken will rise by 9% from €169 to €185 from December 1 when the measures are introduced.

Products also affected by the price hike will be Coors Light, Moretti, Beamish, Foster’s, Murphy’s, Orchard Thieves, Appleman’s, Tiger Cute Hoor IPA, and Lagunitas.

Publicans have reacted angrily to the news, with Liberties-based pub Kavanagh's taking to social media to call for pubs to "collectively take a stand against this madness."

"We would need to increase the pint by 35c to our already hard-pressed customers," the pub said in a post on social media, adding that its customers would "get used to drinking a different lager."

Willie Aherne of The Palace Bar in Dublin tweeted a picture of his Heineken draughts packed up with the caption "zero explanation needed."

Noel Anderson, the managing director of Dublin pubs The Bridge 1859 and Lemon & Duke and the former chair of the Licensed Vintners Association (LVA) in Dublin, described the measures as a "huge kick in the b*lls for publicans". 

"Calls will go in to reverse it but this is simply insane," he tweeted.

Paul Clancy, the CEO of the Vintners Federation of Ireland, told the Irish Independent that publicans were "extremely concerned" about the latest rise in prices, adding that a price hike was the "last thing that customers and publicans need right now". 

"There is never a good time for such a price increase, but in the current climate where everyone is feeling the impact of soaring costs, this is particularly poor timing. Due to the cost of doing business, most publicans will have to pass on the price increase to their customers," Clancy said. 

According to Ireland's Central Statistics Office, in October 2022, the national average price of a pint of stout in licensed premises was €5.15, up 20 cents a pint in the year, while a pint of lager was €5.56, up 26 cents compared with October 2021.
