The problem with having a huge portfolio of great wines is that you have to constantly pop bottles to remind people of your products. But you then risk popping too many, looking desperate or without vision and direction.
The problem with a small and finely tuned portfolio is that once you pop a bottle and the buyer doesn’t see what you see in it, you have no options. But you then can stand your ground and explain why you chose that one wine instead of the dozens (or hundreds — look at Argentine Malbec) available.
Hard to tell which side it’s better to be on.
