RESEARCH INTERESTS

Our main research interest is to understand the chemical basis of flavour, especially in the wine industry. This main line of research is carried out in collaboration with the associated Unit to ICVV: Laboratory for Flavor Analysis and Enology (LAAE) at Universidad de Zaragoza. This is approached following a multidisciplinary strategy combining flavour chemistry, psychophysics and cognitive psychology that is tackled in the framework of specific sublines of research:

 

• Elucidation of the chemical basis of taste and chemesthesic sensations
• Understanding sensory interactions (e.g., aroma-taste, aroma-astringency, taste-astringency)
• Evaluation of the potential and phenolic quality of grapes
• Modeling/optimization of wine aging

The know-how acquired over more than 30 years allow us to offer an integrated analytical service for the most relevant sensory-active components of wine flavor:
 

Research and advice on wine flavor

- Sensory analysis. Characterization of wine flavour
- Identification and characterization of off-flavours  
- Production of aroma and taste references for the training and control of sensory panels
- Advice on the accreditation of panels for sensory evaluation

Analytical service for the analysis of sensory-actives compounds:

Varietal aromas: Thiols, terpenes
Fermentative aromas: Esters, alcohols, acids
Wood-derived aromas: Lactones, vanillins, phenols
Aroma Precursors: Glycosidic and cysteinyl precursors
Oxidation and reduction aromas: Aldehydes, DMS, mercaptans
Other off-odours: TCA, Brett
Polyphenols: Antocyanins, flavanols and tannins, tannin activity
