Jill Jastrzembski selected for Northeast Sustainable Agriculture Research and Education (NE-SARE) Graduate Student Award
Jill’s proposal to NE-SARE, entitled “Defining sulfur spray recommendations based upon the re-emergence of hydrogen sulfide off aromas in wine post-bottling” was recommended for funding. Congratulations! If all goes well, in another year, growers and winemakers will have a better handle on how much elemental sulfur on grapes is really too much.
Farewell to Christine Hansen (MS) and Megan Damen (MPS)
On 7/28/2014, Christine Hansen successfully defended her MS thesis on sulfurous off-aroma emergence in flavored wines. Christine will be starting a job as a Sensory Scientist with E&J Gallo (Modesto, CA) in August Megan Damen submitted her final report on her MPS project, and has completed her degree. She has accepted a job with Diageo Read More…
New publication accepted on tannin extractability (Springer and Sacks, J Ag Food Chem, 2014)
“Protein-Precipitable Tannin in Wines from Vitis vinifera and Interspecific Hybrid Grapes (Vitis ssp.): Differences in Concentration, Extractability, and Cell Wall Binding”. http://pubs.acs.org/doi/abs/10.1021/jf5023274 This was the work for which Lindsay received Best Oral Enology Presentation at the ASEV and ASEV-ES conferences in 2013. Key finding: tannins are much lower in wines produced from hybrid grapes as Read More…
New publication on relative contribution of sugar metabolism to fermentation volatiles in J Ag Food Chem
Collaborative project with Mark Nisbet in Anna Katharine Mansfield’s group, and Tom Brenna’s group in Nutrition Sciences http://pubs.acs.org/doi/abs/10.1021/jf500947x The punch-lines GC-C-IRMS can be used for tracking low levels of 13C labeled tracers during fermentations The major fermentation volatiles (fusel alcohols, esters, fatty acids) are almost entirely formed from hexoses. In the case of fusel alcohols, Read More…
