Viticulture and Oenology
This statewide survey report on vineyards 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 1987 and 1988. According to this report, Oregon wine grape acreage was up but overall production was down in 1988, the result of a lower yield per acre than in the prior year.
