A friend of mine moved to Oxford, Mississippi some years ago. He and his SO walked into a store to get a bottle of wine. When they inquired where the chardonnay was located, the old clerk replied "Son, you gotta go all the way to Memphis to get a bottle of Chardonnay."
About the same time, I drove my sister down to school at Auburn, Alabama. I had a 5 hour drive home on a Sunday afternoon and thought it might be nice to pick up a 6 pack for the empty interstate drive (this was before MADD). But the beer in the convenience store was all locked up. I asked if anyone knew a local bootlegger. Three customers immediately volunteered to show me the way.
But it isn't just Mississippi that has a single state owned wholesaler. Ohio, where I live now, does, too. And that wholesaler gets to choose for the entire state which brands are sold in the state. The result is that we have a horrible selection. Basically, the system allows the state legislators to accept bribes in the form of campaign contributions from the producers who want to get their product on the approved list and keep their competitors off of it.
I once looked at the state liquor commission's web site to see if I could find the approved list. Prominently displayed was the commission's mission statement. Their job, they stated, was to bring in as much revenue as they could for the State of Ohio. A far better system would be to do away with the state wholesaler, open it up to competition that could compete on product selection and customer service and charge a wholesale tax. But then the legislators wouldn't get their kickbacks.
