Makers of the famous stout say they created the guide to spotlight the pubs that represent the best of British pub culture.
The Harp Guide is a roundup of boozers that stand out in five categories: quality pours, welcoming atmosphere, strong community, great service, and a genuine love of Guinness.
And each of the 35 watering holes that made the list will get an official brass Guinness harp plaque to display in the bar.
The London pubs in the guide include award-winning pub The Devonshire near Piccadilly Circus, Soho institution The Coach and Horses, and the Bricklayers Arms in Putney.
Also making the cut were Skehans Freehouse in Nunhead, The Audley in Mayfair, The Fox & Pheasant in Chelsea, and Mc & Sons in Borough, which was founded by brothers John and Ryan Mc Elhinney and their father Jack in 1998.
Perhaps the least surprising addition to the list is The Auld Shillelagh in Stoke Newington Church Street.
This narrow pub, with a large beer garden has been described by The Irish Times as “the most authentic Irish pub in the world outside Ireland”.
From traditional music nights to screenings of Gaelic football games, to a decor of tricolour flags, hurling sticks, and Guinness-branding, it’s a haven for anyone who loves a pint of porter.
Finally, The Toucan near Soho Square has been a pilgrimage site for Guinness lovers ever since it founded in 1994 by owner Colin Taylor.
The name is inspired by the drink brand’s mascot and is a haven for all things Guinness. Adorned with bygone memorabilia from painted toucans flying around the walls to original signage, it’s a true celebration of the famous brand.
The Harp Guide comes as a new Guinness attraction the Open Gate Brewery opens in Covent Garden, complete with bar, restaurants and experiences where you can learn to pour the perfect pint.
Nicholas Payman, head of Guinness at drinks firm Diageo, said: “By shining a light on these exceptional venues we want to recognise pubs and help to drive footfall throughout the year, as well as giving our drinkers advice on where they can find a perfect pint of Guinness.”
