EXPERIENCES WITH SPATIAL VARIATION OF YIELD AND FRUIT COMPOSITION IN PREMIUM VINIFERA VINEYARDS IN NIAGARA

EXPERIENCES WITH SPATIAL VARIATION OF YIELD AND FRUIT COMPOSITION IN PREMIUM VINIFERA VINEYARDS IN NIAGARA

Andrew G. Reynolds & Christiane de Savigny

Sampling a vineyard to estimate yield and fruit composition is a basic required skill for all vineyard mangers and winemakers. It may seem like an easy task, and if done improperly, it probably is. To sample properly, it requires time, skill, and knowledge. This article describes strategies to ensure that vineyard sampling is valid.

An electrochemical method for real time measurement of polyphenols during winemaking

By Christine Pascal, Nelly Champeau, Jean Baptiste Diéval, Stéphane Vidal; Vinventions, Enology team, France

Polyphenols are known to play a major role in must oxidation as well as in wine aging and oxidation. However, they are difficult to measure in the cellar due to lack of adequate technology. Therefo...
