Diageo has had to increase production of Guinness at its St James's Gate brewery in Dublin. The company said yesterday (8 September) that it has upped production of the stout by 50% in order to supply the UK market.

The Dublin brewery, which supplies most of Europe and parts of the US, has seen its annual capacity increase to 12m kegs.

Diageo, which ended its production of Guinness in London last year, has invested around €24m (US$30m) in the expansion of St James's Gate. The site now spreads over 55 acres, employs 1,200 people and accounts for about 40% of Guinness' global production.
