Chemical and chromatic effects of fermentation temperature on three clones of Pinot noir over two consecutive vintages
(American Society for Enology and Viticulture (ASEV), 2022-10-14)Three different Pinot noir clones (115, 777, and 828) from the Central Coast of California were subjected to different maceration temperature regimes for 14 days using triplicate fermentations (Cold: 10°C; Hot: 25°C; and ... -
Chemical and sensory effects of cold soak, whole cluster fermentation, and stem additions in Pinot noir wines
(American Society for Enology and Viticulture, 2019-01)Pinot noir wines were produced over two consecutive vintages using four and six different winemaking techniques in 2014 and 2015, respectively. In addition to control wines, the separate and combined effect of cold soak ... -
Co-fermentation of Syrah with various additions of Viognier: Effect on colour and phenolics during winemaking and bottle ageing
(2013-10)The impetus for the study described in this article was to assess the effect of co-fermentation of Syrah and Viognier in the phenolic chemistry and colour stability of the resulting wines and to document potential benefits ... -
