The Effect of Directly Processing Fruit after Harvest vs Processing after Refrigerating in Cabernet Sauvignon (2016)

This study examines the impact of directly processing fruit after harvest compared with harvesting fruit after it has been refrigerated overnight.  Cabernet Sauvignon grapes were picked from the same block on the same day and were either destemmed into T bins on the same day of harvest or refrigerated overnight before processing the next day.  All other treatments were identical.  The grapes which were refrigerated overnight exhibited slight increases in color intensity, but otherwise no major chemical differences could be found between treatments.  Overall, the wines were not found to be very different.  Very few differences could be seen with descriptive analysis.  These results suggest that refrigerating overnight prior to processing may not have any detrimental effects on finished wine quality.  However, this study should be repeated multiple times, with several different kinds of grapes as well as different levels of grape quality and cleanliness.
