Da Grind Buzz Kona Coffee Imperial Stout is an assertive, rich and hearty dark stout complemented by freshly roasted 100 percent Kona coffee. The stout style is a Russian Imperial stout, historically brewed strong to survive its long voyage from London to the Baltic region. Course ground dark roast 100 percent pure Kona coffee beans were added to the brew during the aging process. The beans were grown and harvested by Cornwell Estate in Holualoa. The brewers were able to watch freshly harvested beans being roasted before transporting them to the brewhouse and adding them to the batch. The beer will be served on nitrogen, giving a smooth, creamy mouth-feel that complements the roasted coffee flavor.
