It used to be the same in Colorado until recently. State law mandated only 3.2% alcohol by weight (~4.0% ABV) could be sold in grocery stores or consumed in state parks. It changed with a state-wide referendum. There is a theory that this law is why craft beer boomed in Colorado. It is easier for small breweries to sell beer through a mom & pop liquor store than a national chain grocery store. Folks were more used to buying beer at liquor stores than other states.
