Jester King Brewery has announced some potential issues with bottles of its collaboration with Quilpué, Chile-based Cervecería Granizo that was released earlier this year.
According to a post on the Austin-based brewery’s Facebook page, bottles of Fearless Traveler have developed “ropiness”, which the brewery describes as “a slick or viscous mouthfeel.”
“The slickness in the mouthfeel is most likely attributable to the lactic acid producing bacteria Pediococcus,” reads the post. “According to the Milk the Funk Wiki, Pediococcus may cause ropiness due to the production of exopolysaccharides, which mostly effect mouthfeel and appearance. Brettanomyces (which is contained in our mixed culture) has the ability to break down exopolysaccharides over time.”
Fearless Traveler is an 6.5 percent ABV farmhouse ale brewed with Merkén—which consists of a blend of ground smoked chilis, toasted coriander and salt—before being refermented with prickly pear cactus fruit. The ale is packaged in 750ml bottles and was released at Jester King on March 28.
This is the second time that Jester King has announced “ropiness” with one of its beers, after the brewery stopped selling bottles of Fantôme Del Rey due to a similar issue less than three weeks after its release in May 2016.
In the post, Jester King indicates that the issue “typically clears up after a few months of aging at cellar or room temperature” and recommends aging any bottles for three to four months before opening them. In addition, the brewery is offering to exchange bottles of Fearless Traveller for a bottle of equal value for anyone who purchased the beer.
