Will Scotland's national drink end up being wine in 70 years? Global warming and the resulting rising temperatures may make barley and wheat necessary for whisky harder to grow. But Professor Richard Selley, of Imperial College London says that just a couple of degrees in average temperature could mean that Scotland's green expanses could support vines. Someday we could all be sipping the Loch Ness Chardonnay. But what is good news for wine does have the whisky industry if not worried then at least aware of the potential challenges for making their product in the future. The whisky makers are already looking for ways to expand production in the face of increasing demand from India and China and with a fairly limited growing area already we could see whisky prices go up dramatically over the next few years.
