Thirty years ago, Connecticut passed the Farm Winery Act allowing wineries to sell wine and hold tastings. The Hopkins family in the town of Warren liquidated their dairy equipment and 250 cows and started planting grapes. Their ancestor Stephen Hopkins came over on the Mayflower and the farmland has been in the family since 1787. Other nearby farmland has also turned to vineyards. Connecticut has a tally of at least 19 wineries in the state.
