Tröegs Independent Brewing is expanding its Splinter Series with the addition of Wild Elf.

The Splinter Series projects are designed specifically to be aged in large wooden fermenters called foeders. These foeders are made of American, French, and Hungarian oak and stand over 23 feet tall; they are housed in the Splinter Cellar brewery expansion.

Wild Elf is a 11 percent ABV, bottle-conditioned strong ale based on the brewery’s Mad Elf, an 11 percent ABV and 15 IBU seasonal release brewed with honey and cherries.

To make Wild Elf, 600 pounds of Balaton cherries sourced from Peters Orchard in Adams County, Pa. were added into the foeder with the base beer for fermentation. House ale yeast was used along with brett, lacto, and pedio strains for fermentation.

Wild Elf is the first large volume Splinter project, it will be available in 375ml bottles.

An email sent to the brewery seeking comment on further details was not immediately responded to.
