Manipulating the peppery aroma of wines: The characterization of rotundone

Becca Yeamans-Irwin - 09 Nov 2016

Rotundone, a guaiane-like compound, has the very distinctive aroma of pepper, with a very low sensory threshold (16ng/L in red wine and 8ng/L in water), therefore is a very important compound in wine that warrants further study.  Initial studies have found rotundone concentrations up to 145 ng/L in Australian Syrah, Mourvèdre, and Durif wines, while another recent study found rotundone concentrations as high as 561 ng/L in European red wines Schioppettino and Vespolina, and white wine Gruener Veltliner.

The perfect Pinot problem

The Economist - 03 Feb 2016

Researchers report in the Journal of Agricultural and Food Chemistry that they detected 49 aromatic compounds in Pinot noir grapes from the two years during both the early and the late sampling periods. Most of these compounds remained at low levels throughout the growing period. However, four of them were found in much higher concentrations in the mature grapes than in the early-season ones.
