Crop Estimation: What Methods Work and Why?
Industry Seminar – Grapegrowing

A lot of critical vineyard and winery decisions are based on knowing the amount of crop in a vineyard. A balanced crop, whether by correct pruning or crop thinning during the growing season, is essential for high quality wine production. Winemakers plan tank and barrel space, and wine marketers want to know how much wine they will have to sell. Crop estimating is an important tool necessary to achieve a balanced crop load. In this seminar we will learn about lag phase research at Oregon State University, as well as crop estimating methods in a small Oregon vineyard and a large Washington winery.
