“Now in its 16th vintage, 2023 Eclipse is our rich Imperial Stout aged to perfection in whiskey and spirit barrels. All Eclipse starts with the same base beer bringing hints of dark chocolate, espresso, and a smooth complexity, with each barrel treatment delivering its own unique character after a minimum of 180 days aging. Old Trestle Bourbon Barrel is aged exclusively in Old Trestle Sierra Bourbon Barrels from Truckee, CA.” FiftyFifty Brewing Co
