It is already a favourite at Cheltenham Festival and now sales of Guinness have surged post Covid.

Released back to the pubs, the nation quenched its thirst for the black stuff in droves with sales up 32 per cent in the last six months of 2021.

Diageo, which makes the Irish stout in Dublin, found its pot of gold on St Patrick's Day this year when 1.8million more pints of Guinness were sold than in 2019, reports The Sun. It said sales of Guinness now account for roughly one in ten pints ordered in the UK.

The iconic drink is a favourite at Cheltenham Festival, perhaps due to the fact the Irish patron saint celebration day falls within the four-day event.

Up to 300,000 pints of Guinness are consumed by racegoers each year at a cost of £7 each. That means the bars rake in more than £2million in Guinness sales over the event.

Lucky Diageo.
