Despite price hikes, Guinness-owner Diageo still misses profit forecast 

Alongside Guinness, Diageo also produces Johnnie Walker whisky, Rockshore, and Hop House 13. 

Despite a number of price increases over the last few years, Guinness-owner Diageo has reported a 4.8% decline in annual profit due to a steep decline in sales in Latin America and the Caribbean.

The world's top spirits maker has been battling to restore investor confidence after a build up of unsold inventory in Mexico and Brazil led to a profit warning and a loss of market share in its biggest territory, the US.
