This bottle has a 100% Rye mash bill, which is unique to other blended rye whiskies on the market. Initial aging is in typical new American charred oak for the first two years, then rests in a second handmade custom barrel for an additional 6-18 months. The second barrel is toasted & charred over a wood fire, thus developing a depth of natural sugars creating caramels & vanillas along with the spicy rye grain taste. This has become a signature bottle for our brand. Each batch is unique to that batch and barrel. The mash bill is always the same, but the barrels offer unique profiles that influence each bottling. This makes each batch as unique as the trail it's named after. Always amazing and intentionally never the same experience.
