The Emerson family operated Brotherhood until Prohibition. In 1921, Louis Farrell purchased the winery and its large stock of sacramental wine. He sold wine for religious ceremonies throughout Prohibition, which was finally repealed in 1933. It has been noted that the clergy population in the area grew substantially during this period.
Louis and his wife were the first to grasp the value of Brotherhood’s location, as the nearest winery to New York City. They began conducting tours of the winery, highlighting the now-enlarged underground cellars, the history of the facility and its picturesque site. In fact, the Farrell family initiated the very concept of wine tourism, hosting parties and events at the winery that drew hundreds of thousands of fans annually, and introduced the Brotherhood brand to generations of American drinkers.
