I opened one of my bottles of 2015 Goose Island Bourbon County Stout that I had been storing in my basement on Thanksgiving, aged it for 2 years (shy one day). OMG. The beer is good "fresh" out of the bottle but after it is aged for a couple years, best beer I've ever had (and I am usually an IPA guy). Because of the aging, almost all of the booziness was gone and it was incredible smooth and flavorful. Still have a few more to either age or open this year and picked up 8 bottles of the 2017 BCS this year.
