The range includes Petrus Aged Pale 'The Mother Beer' (7.3% ABV), a foeder beer aged for one year, Petrus Oud Buin (5.5% ABV), a traditional Flemish red brown beer and Petrus Aged Red (8.5% ABV), a dark fruit beer.
Petrus Aged Pale was not originally intended to be bottled because it was used only as a blending beer but, upon visiting the brewery in the late 1990s, beer writer Michael Jackson struck a deal to have it released.
What is a foeder?
A foeder is a wooden barrel that lets in air to create a wild yeast fermentation environment, unlike a traditional cask.
Albert De Brabandere, retail manager at De Brabandere, said: "De Brabandere has never compromised on taste, quality or ingredients and the Petrus sour beers are no exception.
"We are excited to be working with Boutique Bar Brands to bring Petrus sours back to the home of beer hunter Michael Jackson, who encouraged us to take the Petrus Aged Pale from foeder to bottle."
The brand is also encouraging customers to create their own original blends by mixing the range together to find new flavours.
De Brabandere added: "[The beers'] distinctive flavour has garnered a strong international following and we're looking forward to hearing about the unique blends created by British beer lovers."
