On my recent trip to northern Italy, my wife and I went on a two-day wine tour.

I asked a lot of questions.

I wanted to learn about the winemaking process and draw parallels back to investing.

Needless to say, they share a lot of similarities.

The big question I asked: What percentage of making good wine are you, the winemaker, responsible for? 

I wanted to learn if the weather, soil and other elements out of their control was mostly responsible for the taste in good wine.
