While the Pennsylvania wine industry was established early in the history of the European settlement in the state, the current industry was spawned relatively recently by virtue of the Pennsylvania Winery Act in 1968. The industry is widely distributed, with wineries and wine grape production throughout the state, however the primary center of production is in southeastern Pennsylvania, where climatic conditions allow for the production of some of the hardier European wine grapes. A second, much smaller cluster of production is along Lake Erie, within the zone of more temperate weather induced by the lake. A third region is scattered throughout the harsher environments of the rest of the state. These regions are characterized not only by climatic differences, but by differences in producer demographics, clientele, pest complexes, cultivar preferences and obstacles to production. The industry is built primarily on French-American hybrid production, however European grapes are being produced, are in demand, and as such, are commanding relatively high prices.
