Researchers seeking grape samples

Beth Costa on Sep 7, 2020
All –
Two well-respected researchers who many of you know – Drs. Anita Oberholster and Elizabeth Tomasino – have asked that we advise industry members of their plan to review historical atmospheric data in developing risk models to mitigate damage from smoke.  They would like to incorporate samples from the 2020 harvest and need to collect grapes and/or wine samples that may have been impacted by smoke.  Please feel free to share their instructions below with any interested growers and wineries in California, Washington and Oregon. 
Many thanks, Michele

Researchers at UC Davis and Oregon State are seeking samples from grapes or wine from the 2020 harvest that might have been impacted by smoke exposure.  These samples will enable them to study atmospheric data with the goal of mitigating damage as a result of exposure to wildfires and smoke.  Grape and / or wine samples will be stored until funding is secured, and the study gets underway.  Please note: this is not meant to be an alternative to having samples analyzed by commercial labs. Results of the study will not be available for months or years to come
If you would like to participate in this study, please follow the instructions below. 
Please notify the following researchers of your interest in participating in the study before sending any samples:
Dr. Elizabeth Tomasino, Associate Professor of Enology, Oregon State University @
Dr. Anita Oberholster, Associate Specialist in Cooperative Extension in Enology, UC Davis @
Please send either grape clusters or wine (or both)
·       Please submit unblended wine with no oak/wood contact. 
·       Only 1 sample per vineyard for each variety, please. 
·       Grapes – 1-2kg
·       Grapes should be frozen and shipped frozen in Styrofoam when possible
·       Wine – 375mL
·       Wines should be well sealed with little to no headspace
·       For customs forms, contents should be listed as research samples (not for consumption or sale)
 Each sample must include: 
·       GPS coordinates for grape origin
·       Grape harvest date
Please provide as much detail as possible related to: 
·       Grape variety
·       Rootstock
·       Clone
·       Vine age
·       Type of trellising
For wines:
·       Yeast and/or MLF used for fermentation
·       Fermentation temperature
