Like many London bar and pub owners, Mr Brown has every reason to worry that he is not serving enough stout to his customers.
Those deemed substandard risk being featured on the popular Instagram page 'Sh – London Guinness', their venues named and shamed and their bubbly beers predominantly Irish. He has been ridiculed by his 250,000 followers.
Guinness advertising did not mention double pours until the 1990s.
Previous ads either didn't depict pints being poured, or they usually depicted them pouring from the bottle all at once.
The 1994 “Anticipation” ad was the first to show Guinness waiting to settle before being refilled to the brim.
It ends with the catchphrase, “There's no time like Guinness Time.''
This lasted from the mid-1990s to the mid-2000s under the tagline “Good things come to those who wait,” but then gradually changed in favor of the phrase “Made of more.” Obsolete.
A recent Guinness ad doesn't depict a double pour at all, nor does it mention waiting.
Guinness has skyrocketed in popularity over the past few years, becoming the best-selling beer in pubs, bars and restaurants by 2022, according to hospitality data firm CGA.
Sales of the drink have also increased among young women, with the number of women drinking stout increasing by 24% as the brand has successfully shed its “rugby boy” image.
