This 2 1/2 minute video looks at the 3-tier system and how it affects the price of wine. As a small caveat, each state is in charge of their own alcohol laws so the structure and functions of alcohol control will look different state to state. Also, I am not trying to pass judgment on or vilify any part of this system, just explain what their roles are.
Stayed tuned for Part 2 which explains the elements that change cost in the production of wine!
