Viticulture and Oenology
This statewide survey report on vineyards and wineries in Oregon covers bearing and nonbearing acres, size of vineyard operation, variety and county, size distribution, prices, and yields. The report also contains some comparisons of data for 2003 and 2004. According to this report, Oregon wine grape production was down for a variety of reasons: poor fruit set for some growers, freezing temperatures, powdery mildew, birds, yellow-jackets, and deer.
