Contrary to what a lot of people think, there's a clear difference between cheap and expensive alcohol. Hennessy VSOP, for instance, is miles away from Hennessy XO. Expensive champagne, too, tastes very different when compared to cheap champagne (technically, cheap sparkling wine). The first tell sign is that it also looks very different when poured - that's probably the quality of the grapes and the aging process showing.
You might doubt it, but we ran a little experiment to test our hypothesis. A couple weekends ago, we got a few friends of the blog and EDL readers together for this very fun video. We wanted to see if people could tell the difference between cheap vs expensive champagne.
They were mostly right in the sight test but some people got a bit confused during the tasting phase. Be sure to leave your thoughts in the comments!
