White Labs introduces WLP546 Marañón Canyon Wild Cacao Yeast
White Labs , the commercial yeast laboratory out of San Diego has teamed up with Marañón Chocolate to isolate and produce a wild yeast WLP546 Marañón Canyon Wild Cacao from rare cacao variety - Pure Nacional. The rare cacao bean was thought extinct in Peru but was rediscovere in 2007 by Dan Pearson and Brian Horsley, founders of Marañón Chocolate.More from a press release:Not knowing what they stumbled upon, the pair sent the cacao tree leaves to the USDA Genetics Laboratory. USDA confirmed it was the same variety that had once dominated the chocolate market, but vanished in 1916 when diseases struck and killed the trees that grew these cacao beans.Then, in 2015 and 2016, El Niño weather systems hit Peru, impacting the wild yeast responsible for the beans renowned characteristic flavor. To preserve the wild microflora, Pearson reached out to Kara Taylor, technical laboratory manager at White Labs, to see if the international yeast company could capture the wild yeast from fermenting beans. They succeeded.“After they successfully isolated the wild cacao yeast, our next thought was ‘can you make beer with it?’” said Pearson. “So I asked Kara if she thought it was possible, and she told us that the odds of isolating and stabilizing a wild yeast were very slim, but that they would try, and fortunately for us, they did!”
“I was skeptical that we would find a wild yeast on the cacao that had the capabilities to ferment beer,” noted Taylor. “We love to find yeast in unique places, but it’s unusual to find yeast that will ferment maltose while tasting and smelling good. In this case, we found a unique strain that creates a farmhouse type aroma and flavor profile.”On top of isolating and propagating this cacao yeast, White Labs also brewed a test batch of beer which captured the esteemed fruit, floral and spicy flavors that the chocolate is known for producing. White Labs found that WLP546 Marañón Canyon Wild Cacao produces fruity, phenolic, and wild-like characteristics that make it an ideal choice for farmhouse and saison-style beers.WLP546 Marañón Canyon Wild Cacao is being released through the White Labs Vault, making it available for professionals to order year-round. Homebrewers can pre-order the strain through The Vault for Homebrewers.For more information, visit whitelabs.com/yeastbank.
