Having worked in high end bars in 5 major citys around the world for best part of 9 years, done 21 different wine tasting courses in 3 different countries and hold a WSET level 5 honours diploma and since become a wine collector, i think i am able to express my opinion.

I believe about 2% of people i have ever served champagne to in a bar have ordered the drink because they enjoy drinking it over other drinks. The 98% are purely poseurs and those celebrating. I would say 2% of champagne drinkers know anything about champagne or could tell a bad one from a good one.

I aso look at global sales figures.
