ate the fresh berries and used the dry fruit in pemmican. They apparently did not, however, ferment the grapes into wine. The early settlers called it the ''frost grape'', as it was best when picked after the first hard frost. With the influx of settlers in the 1840s and '50s, grape growing was tried along with all other horticultural pursuits. Varieties developed on the eastern seaboard such as the Concord were somewhat successful. The fruit was commercially used for fresh fruits or preserves. No wine was made except for personal use. However, these eastern varieties were not quite hardy enough and the coldest of winters, together with the growth of the California fresh fruit industry, eventually did the industry in. By the 1930s grape growing was limited to backyard vineyards for family use only. The first winery in this region,

Climate and geography
