"Sure, there are lots of whiskies that are only for sale in a limited area, but usually that is because the distillery is small and they don’t make a huge amount. But it’s different when a distiller or a brand that’s nationally distributed decides to get out the Sharpie and make a circle on the map, and say, 'Only here. Nowhere else.' It’s kind of special, and the reasons often make it even more so."
Geotargeting is an interesting phenomenon and we're suspicious any time something "special" comes along with a good marketing angle and higher price.
