Grain-to-glass whiskeys typically come from smaller farm distillers, so when the term is used by a larger distiller, people are often wary. But Heaven Hill has crafted an excellent version, working with Indiana-based seed company Beck’s Hybrids and Peterson Farms in Kentucky to grow the grain, some of it in fields across from Heaven Hill's warehouses. The mashbill has a high rye content of 35%—roughly three times more than Heaven Hill’s other bourbons. You can taste its spicy influence amid flavors of vanilla, almond, chocolate, cinnamon, and coffee, accented by licorice, orange, and jalapeño pepper spice. —David Fleming
