Each player takes control of a vineyard and tries to create delicious wines. This takes a lot of skill as the players have to manage the normal part of every management game (employees, buildings etc.) but also have to select which type of grape to use and when to harvest. What type of wine to create, how long to wait and so on.
A lot of knowledge about wines is needed to be successful so it is a hard game for beginners. But thanks to its complexity and the gained knowledge it is a jewel.
