Co-fermentation of Syrah with various additions of Viognier: Effect on colour and phenolics during winemaking and bottle ageing
Casassa, Luis Federico; Keirsey, Landon S.; Mireles, María S.; Larsen, Richard C.; Harbertson, James F. (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 ... -
Effect of extended maceration and ethanol concentration on the extraction and evolution of phenolics, colour components and sensory attributes of Merlot wines
Casassa, Luis Federico; Beaver, Christopher W.; Mireles, María S.; Harbertson, James F. (Wiley, 2013-02)Background and Aims: Anecdotal evidence suggests that there may be a synergistic effect of ethanol (EtOH ) and prolonged skin contact on the extraction of certain phenolics that may negatively impact wine sensory properties. ... -
Extraction, Evolution, and Sensory Impact of Phenolic Compounds During Red Wine Maceration
Casassa, Luis Federico; Harbertson, James F. (2014)We review the extraction into wine and evolution of major phenolic classes of sensory relevance. We present a historical background to highlight that previously established aspects of phenolic extraction and retention into ... -
Influence of fruit maturity, maceration length, and Ethanol amount on chemical and sensory properties of Merlot wines
Casassa, Luis Federico; Beaver, Christopher W.; Mireles, María S.; Larsen, Richard C.; Hopfer, Helene; Heymann, Hildegarde; Harbertson, James F. (2013-12)Selected winemaking conditions were applied to fruit with ~20.3 and ~24.9 Brix over two seasons. Merlot grapes were harvested 33 (2011) and 34 (2012) days apart. At each harvest, half of the must was adjusted to emulate ... -
Modulation of flavonoid biosynthetic pathway genes and anthocyanins due to virus infection in grapevine (Vitis viniferaL.) leaves
Gutha, Linga R.; Casassa, Luis Federico; Harbertson, James F.; Naidu, Rayapati A. (BMC, 2010-08)Background: Symptoms of grapevine leafroll disease (GLRD) in red-fruited wine grape (Vitis vinifera L.) cultivars consist of green veins and red and reddish-purple discoloration of inter-veinal areas of leaves. The ... -
Regulated Deficit Irrigation Alters Anthocyanins, Tannins and Sensory Properties of Cabernet Sauvignon Grapes and Wines
Casassa, Luis Federico; Keller, Markus; Harbertson, James F. (2015-04)Four regulated deficit irrigation (RDI) regimes were applied to Cabernet Sauvignon grapes, which were analyzed for phenolics and also made into wine over three consecutive growing seasons. Relative to an industry standard ... -
Sensory Impact of Extended Maceration and Regulated Deficit Irrigation on Washington State Cabernet Sauvignon Wines
Casassa, Luis Federico; Larsen, Richard C.; Beaver, Christopher W.; Mireles, María S.; Keller, Markus; Riley, William R.; Smithyman, Russell; Harbertson, James F. (2013-12)Irrigation practices such as regulated deficit irrigation (RDI) and winemaking practices such as extended maceration have been experimentally evaluated from a chemical perspective but their impacts on sensory composition ...
