Chemical and sensory evaluation of Bordeaux wines (Cabernet sauvignon and Merlot) and correlation with wine age


This study was carried out on 24 vintages of Cabernet sauvignon and on 7 vintages of Merlot produced by two different Bordeaux growing areas. Proanthocyanidin monomers and oligomers, and several parameters of the proanthocyanidin fraction were analytically assessed. Sensory analysis concerning astringency and bitterness was also performed. The different wines show a variation in several parameters of proanthocyanidin composition, which are correlated with wine age. Perceived astringency is correlated with the proanthocyanidin degree of polymerization (mDP), which is in turn linked to vintage. Merlot wines show sensory and analytical differences from Cabernet sauvignon wines.

Aroma profile of ‘Pedro Ximenez’ sweet musts obtained from dried grapes by different methods

Aroma fraction of musts from grapes ‘Pedro Ximenez’ traditionally sun-dried and chamber-dried at 40 ºC and at 50 ºC during 8, 5 and 4 days respectively, destined for the production of sweet wines in Montilla-Moriles region (southern Spain) was studied.

Oak wood influence on the organoleptic perception of red wine

Some wood substances such as ellagitannins (vescalagin, castalagin, grandinin, roburins (A, B, C, D, E)…) can be extracted during wine ageing in oak barrels. The level of these hydrolysable tannins in wine depends of the species and origin of oak wood as well as its treatment during barrel realization.

Sensory evaluation of ‘Sauvignon blanc’ grapes by a trained panel

The study described the effect of sensory analysis on commercial ‘Sauvignon blanc’ vineyards within the Stellenbosch Wine of Origin District. The sensorial evaluation of the berries was able to give a description of each parcel type and relate it to the cultural practices.

Uvalino wine: chemical and sensory profile

The evaluation of different chemical compounds present in Uvalino wines was correlated with sensory analysis. The analysis showed a high content of polyphenolic compounds responsible for the organoleptic properties of wine, including color, astringency and bitterness.

Perceptive interactions and wine typical fruity aroma 

In this study we developed a methodology to prepare aromatic reconstitutions from fractions of a wine organic extract and we assessed these reconstitutions both in wine model solution and in de- aromatized wine.
