Who drank all the bubbly?

A report from Bloomberg warns that we'll soon be seeing a shortage of Champagne due to increasing demand from the UK, USA and Japan. High demand and low supply will inevitably lead to higher prices, which is probably a good thing for the producers. But according to the article, the Comite Interprofessionnel du Vin de Champagne (CIVC) is intending to extend the Champagne region in order to increase output over the next few years.
