Silver City Brewery Barrel Aged Series These handcrafted, small batch releases offer a wide variety of beer styles aged in any variety of oak barrels. Wine, bourbon, rye whiskey or other oak barrels elegantly enhance, dramatically alter or creatively amplify the flavors of the beer the brewer has created. The Silver City Brewery Barrel Aged Series are rare and unique brews with as few as 100 bottles produced. Each beer in the series is different than the next. We hope you enjoy our carefully handcrafted barrel-aged creations.
