Tom Collins

Grape and wine chemistry research

In the state-of-the-art analytical chemistry laboratory and research winery at the new Ste. Michelle Wine Estates WSU Wine Science Center, Tom Collins uses advanced analytical instrumentation and multivariate statistical tools to study the composition of grapes, wines and distilled spirits. He evaluates composition changes while fruit ripens, throughout the winemaking and distilling processes, and as these products age. The goal is to better understand how vineyard, winery and distillery practices affect the composition of grapes, wines and spirits and to correlate chemical composition with sensory perception of these products.

Specifically, the analytical chemistry laboratory equipment includes:

  • Gas chromatography solid-phase micro-extraction/mass spectrometry (GC-SPME/MS) for profiling volatile composition
  • Ultra high-pressure liquid chromatography-quadrapole time of flight mass spectrometry (UHPLC-QTOF/MS) for non-volatile profiling
  • Microwave plasma emission spectroscopy (MP-AES) for metals analysis
