A bottle of Bourbon County is ~$5 and 15% ABV. Many craft beers are $1.66 per bottle ($10/6pk) and ~5% ABV. If you do the math by $/ABV a Bourbon County is equivalent to many other beers. As others have stated there are many reasons that Imperial Stouts can be costly to make, just as Hops add costs to IPAs. I think you have grossly over exaggerated the difference.
