Pumpkinator

 Introduced in 2009, under another name. Returned to market in 2011, under the current title. Brewed in Texas by Saint Arnold. 

"Everything is a little over the top with our Imperial Pumpkin Stout, which perversely makes it balanced. Beyond the big malt bill, it has pumpkin (lots of it), molasses, brown sugar and a healthy load of spices. It’s 10.5% ABV which makes it a dessert by itself or the perfect accompaniment to your holiday meal.

This is also a beer that ages magnificently. Many really enjoy it most after a year or two. If you do want to lay some down, it is best to age this beer at cold temperatures (your refrigerator is highly recommended over your closet)."
