Alongside fellow judges, Le Gavroche head sommelier David Galetti, head chef Rachel Humphreys, MasterChef series co-presenter Greg Wallace, Silvano Giraldin, and Luke Finegan, sous chef at Roux at Parliament Square, Michel and Albert said the five stood out among the varied flavours and styles that were submitted by 12 London breweries.
"We were amazed at the complexity and originality of the beers that were entered into the competition, but we drew up our shortlist from those that we felt would best pair with the fresh flavours that characterise our summer menus," said Michel Roux Jr.
The winner of the Roux Brew will be announced at Roux at Parliament Square on 7 March at an event attended by the five shortlisted brewers, all of whom are members of the London Brewers' Alliance (LBA).
Brew by Numbers - Saison - 5.6 ABV - hibiscus, chamomile, Seville orange zest, Amarillo hops, raw and malted wheat.
By the Horns - pale rye ale - 5.2 ABV - lemongrass, lime zest, rye malt and Sorachi Ace hops.
Fourpure - Belgian-style - 5.6 ABV - Belgian yeast, fresh pink grapefruit zest, fresh Sicilian Navelina orange zest, and coriander seed.
Hackney - pale ale - 5 ABV - Nelson Sauvin hops, fresh crushed gooseberry and grape infusions.
Windsor & Eton - golden ale - 5.3 ABV - locally grown (Windsor Royal estate) floor malted barley, Waimea and Saaz hops, pink peppercorns and thyme.
The Roux Brew will be a special 'house' beer to be paired with summertime food at Le Gavroche, Roux at Parliament Square and Roux at the Landau restaurants.
The listing will be guaranteed from April until the end of September, and a competition for a second brew for winter menus is planned for the autumn.
The LBA was formed in 2010 as a collective of London breweries within the M25 to celebrate the resurgence of brewing in London. Le Gavroche was among the first quality restaurants to establish a beer list. This now extends to 17 choices. Michel Roux Jr is keen to expand that choice and to promote the matching of beer and food in his restaurants.
