Sir: Following a year of massive investment by Diageo GB, which has seen media spend on Guinness top £7m, I was surprised to see the UK’s leading stout was omitted from the Top 10 Advertisers list in your Focus On Beer & Cider (29 June).

At Guinness, we are proud of our pint and our significant investment has seen us communicate that Guinness is ‘Made of More’ through celebrating the amazing things that happen when you choose to be extraordinary. This March and April alone saw an impressive £2.2m investment, which included TV and print advertising and in-outlet activity.

We will continue to support Guinness over the coming months through significant investment in the amplification of ‘Made of More’. This includes innovative mobile and experiential technologies, our unique on-trade Quality Accreditation programme, demonstrating the importance of the perfect serve, and our new status as the Official Beer of England Rugby.

We remain one of the biggest investors in the UK beer & cider category and are excited about the future for Guinness.

Nick Britton, marketing manager Guinness Western Europe, Diageo

The editor responds: The Ebiquity table in question did not include ales and stouts and should have been headed Lager & Cider rather than Beer & Cider. Apologies for any confusion caused.
