Diageo has imposed limits on Guinness orders for UK pubs due to unprecedented demand, while production operates at full capacity. Despite the restrictions, publicans remain optimistic about customer turnout as sales of Guinness continue to rise, particularly among younger drinkers post-pandemic. The trend is affirmed by research data showing a significant increase in keg sales compared to overall beer consumption. Meanwhile, the supply of Guinness in Ireland remains unaffected, as Diageo confirmed all deliveries will proceed without disruption.
