That is hard isn’t it? We can start to list some things like sweet or tart, cold, refreshing, strong, but it all blends into some odd muttering that ends with the statement “you know?”
So the answer is it is everything that makes it our favorite. Even some things that aren’t in the drink make it special. The memory of a moonlit beach with that drink has a lot of power.
How do we expect to make or keep ourselves as our customer’s favorite drink? If they can’t tell us why it (we) are their favorite, how do we make sure we are doing what it takes?
Provide the right ingredients, mix it well, and provide the right kind of experience, and how could it go wrong? Every interaction you have with them builds the experience, whether it is a moonlit night or a typhoon.
