Evaluation of the quality performance of the clones of Pinot Noir

Abstract

Pinot Noir from four sites at two different yield levels and from seven different Clones were assessed in an unbalanced trial. A total of 23 combinations of Site*Clone*Yield were assessed.

Important results include:
A significantly higher wine score at lower yields when comparing 7 t/ha and 10 t/ha treatments.
Significant differences between sites for Gycosyl Glucose and ß –ionone concentration.
Clone effects for berry mass and organoleptic mouthfeel characteristics.

Pinot noir growers and researchers can use the ranges of measures presented as benchmarks for further research.

Summary

Pinot noir is a variety grown for the production of premium, still and sparkling wine in Australia’s coolest vineyard climates. Pinot noir is a genetically variable variety that is responsive to yield and site in terms of wine quality. The aim of this work is to develop the understanding of these influences in order to guide growers in managing viticulture to grape quality specifications.
