The purpose of this publication is to provide economic information to New York grape growers who are interested in planting Concord and/or Niagara grapes. Industry trends in production and prices since 1978 are discussed. The year 1978 was chosen as a year for comparison because there was a similar study done in that year (White and Jordan) against which the results can be compared. It should be noted that in 1978, the farm value of utilized production in New York State was $45.9 million, the highest on record, Estimates of yields, costs, and returns are provided. The publication is intended to provide growers with guidelines to use in developing their own costs and returns for Concord and Niagara grapes.
