In their words

Old Stone Stack is the nickname of the original Iron Furnace located just down the road and across the river. A big, dark beer made with NH maple syrup, coffee, and chocolate, this stout is a seasonal favorite of many. We serve this beer in a smaller serving due to the alcohol content. Consider letting it warm up just a bit to bring out its robust flavors.
