(Concordmonitor) - A national group of wine sellers is accusing the New Hampshire Liquor Commission of abusing its power and using “gangster tactics” to block wine shipments from out of state, the latest in an ongoing spat between the two groups over sales.

In a strongly-worded statement Monday, Tom Wark, executive director of the National Association of Wine Retailers, took aim at the commission’s move to block the sales of 80 out-of-state sellers from shipping into the state.

According to a Liquor Commission spokesman, the sale bans have been enacted against vendors who were unfairly competing with the commission, which regulates the sale of all alcoholic beverages in the state and operates stores.
