I found this coffee summary compiled (here) from the book “You Are WHY You Eat: Change Your Food Attitude, Change Your Life” ( Dr. Ramani Durvasula) . The summary is made on the study conducted of 1,000 coffee drinkers.

Who am I?
I love cappuccino so I am supposed to “enjoy being in control” and I am supposedly perfectionists…
Sometimes I drink decaf and then I am ” more likely to be obsessive and controlling”
In summer I love frappuccinos and then I am a ‘trendsetter’ and enjoy trying lots of new things. I can also be considered socially bold and reckless.
So to sum up: I am obsessive, and enjoy being in control. I am a perfectionist and also reckless. I am socially bold and enjoy trying new things.
Woow.. such a personality I have 😉
