Smoke, Wine, and Grapes Analytical Chemistry Lab

Smoke Research Facility

The new state-of-the-art research lab was designed to serve the Oregon wine industry to test for the presence of compounds associated with smoke in grapes and wine


Our aim is to provide the Oregon wine community with timely and accurate chemical analysis data so they can make decisions on potentially smoke impacted wine products.


Smoke Analysis

  • Free-phenol analysis – includes data for guaiacol, 4methylguaiacol, o/p/m-cresols
  • Bound-phenol analysis – uses acid hydrolysis to provide best estimates on total smoke phenols present

Other Chemical Analyses

  • Volatile thiol analysis – provide analysis for compounds impacting white wine flavors, such as 3-mercaptohexan-1-ol (3MH), 3-mercaptohexylacetate (3MHA), 4-methyl-4-mercaptopentan-2-one (4MMP)


  • Agilent Liquid Chromatography MS/MS
  • Agilent Liquid Chromatography – Quadrupole Time-of-Flight (LC-QToF)
  • Agilent Gas Chromatography MS/MS
  • Agilent Gas Chromatography Quadrupole Time-of-Flight (GC-QToF)
