Assessing the impact of temperature on grape phenolic metabolism

Creator:

Cohen, Seth D.

Abstract:

Many climatic factors influence grape berry composition including nutrient status, water availability, biotic stress, sun exposure and temperature. Previous research examined the effects of many factors listed above and much progress has been made. It is often difficult, however, to separate effects that typically confound each other, such as sun...

where larger tannin polymers are associated with astringency and ‘mouthfeel’ or ‘texture’ of wine
Development of a method to measure protein in red wines : a survey of protein, mannan and tannin in Pinot noir wines

Creator:

Smith, Mark R.

Abstract:

A number of methods to isolate and quantify protein in Pinot noir wines were evaluated. The combination of precipitation by acetone containing 10% w/v trichloroacetic acid followed by quantification with the Bradford assay, reported in yeast invertase equivalents yielded the most accurate results when compared to micro-Kjeldahl analysis. The technique...

Investigating the effects of temperature on secondary metabolism in Vitis vinifera L. cv. merlot berries

Creator:

Cohen, Seth D.

Abstract:

Grapes (e.g. Vitis vinifera L.) are one of the more important fruit crops from an economic standpoint with world market values over 550 million US dollars in 2007 and 2008, second to apples (United States Department of Agriculture). While a satisfactory level of ripeness is of primary concern, the quality...
