Ferus SpontaneousBrewmaster's Collective Exclusive Ferus Spontaneous is a blend of one, two, and three year old koelship cooled, spontaneously fermented beer. The beer was aged in American oak and select barrels from the last three seasons were blended together in the Belgian Gueuze tradition. Years in our hearts and in the making, this beer has aromas of meyer lemon zest, a tangy, funky character and a crisp effervescent mouthfeel. Cheers to making dreams come true!
