The real threat of global warming

The worst part of global warming? It's threatening bourbon production in the U.S. In order for bourbon to age and take on the flavors of the barrel it's stored in, it needs to expand into and contract from the barrel itself. This expansion and contraction is a function of the ambient temperature in which the barrels are stored. So sensitive is this temperature variation that barrels are moved from the bottom racks to upper racks during the aging process. As such, if global warming continues to make winters warmer in Kentucky, it will adversely affect the whole aging process.
