Research Project: Impact of Pediococcus spp. on the Quality of Washington and Oregon Red Wines

Location: Horticultural Crops Research

Project Number: 5358-21000-042-09
Project Type: Grant

Start Date: Sep 01, 2011
End Date: Jan 31, 2014

Objective:
1. Isolate and identify Pediococcus spp. from Oregon wines. 2. Determine the impact of Pediococcus spp. from Oregon and Washington wines on wine quality. 3. Evaluate the effect of sulfur dioxide on pediococci.

Approach:
Wines will be produced from both Syrah and Pinot noir grapes and inoculated with pediococci previously isolated from wines. Bacterial growth, changes in chemical composition (volatile acidity, diacetyl, etc.), and the synthesis of biogenic amines will be determined using already established methods. Wines will be further analyzed by sensory evaluation using a trained panel.
