Fermentable Nitrogen: Is it Better to Manage in the Vineyard or Winery? (with tasting)
Date & Time
Wednesday, February 12, 2020, 3:00 PM - 4:30 PM
Paul Schreiner Patty Skinkis James Osborne
Description

Fermentable nitrogen can be managed in the vineyard through vine nitrogen additions or in the winery through amendments. There has been a preference of winemakers to avoid nitrogen additions in the winery, opting for nitrogen management in the vineyard. However, many growers are concerned about adding nitrogen in the vineyard for fear of overly vigorous vines and potential for reduced wine quality. This session will share results of a multi-year, multi-vintage study where nitrogen applications were made in the vineyard and winery to adjust fermentable nitrogen levels of the fruit and must. Viticulture, wine production, and sensory results will be shared, including a technical tasting.
