Part of their High Peaks Series... From the label:

Mt. Marcy, Skylight, Algonquin... Majestic Adirondack High Peaks - They are the inpiration for our "High Peaks" series. A line of beers that are bigger, more complex and flavoerful: Beers that are meant to be sipped and savored. The second in our series, Saranac Imperial Stout, is brewed with eleven malts to balance a delicious chocolate and coffee roasted flavor with the spicy herbal character of the generous kettle and dry hops. At 50 IBUs this beer captures the essence of the Adirondacks. Enjoy!

We love Imperial Stouts, so can't wait to try this one! Hope we get it in Boston!
