Boulder's Roundhouse Spirits  says a little piece of Arapahoe Glacier ends up in every one of their bottles of small-batch gin, coffee liqueur, and pumpkin cordial. See if you can taste the difference in this martini made with their Imperial Barrel Aged Gin , sometimes called "ginsky" for its scotch and whiskey flavors.
2 ounces Roundhouse Imperial Barrel Aged Gin
1/2 ounce Tart Cherry Liqueur  (or tart cherry juice)
1 ounce sweet vermouth
Dash of orange bitters
Orange slice or maraschino cherry
Mix gin, cherry liqueur, sweet vermouth, orange bitters, and ice and strain into a martini glass. Garnish with a slice or zest of orange or a maraschino cherry.
