Manipulating Soil Moisture and Nitrogen Availability Part II: Effects on Pinot noir Must and Wine Composition

Creator:

Watson, Barney, Godard, Mee, and Chen, Hsiao-Ping

Abstract:

The objectives of this study are to evaluate the effects of manipulating soil moisture and nitrogen availability using different approaches, including supplemental irrigation, nitrogen addition to the soil or to the leaves, and the elimination of competition for water and nutrients between the ground cover and the grapevines by tilling....

Manipulating Soil Moisture and Nitrogen Availability Part II. Fermentable Nitrogen Content and Must and Wine Composition

Creator:

Watson, Barney, Wall, Kate, Specht, Anna, Chen, Hsiao-Ping, and McDaniel, Mina

Abstract:

An approximation of the total yeast fermentable nitrogen content in juice or must is taken as the sum of the nitrogen available from ammonia and the alpha-amino acids present (Bisson 1991 ; Dukes and Butzke 1998 ; Jiranek, Langridge, and Henshcke 1995). Recommended levels of fermentable nitrogen needed by yeast...
