Some of these studies analyzed the relationship by applying methods such as quantitative descriptive analysis (Campo et al., 2010, Ortega-Heras et al., 2010 and Parpinello et al., 2009) or by evaluating consumer preference using multivariate statistical tools Erlotinib ic50 such as the Principal Component Analysis (PCA) (Chira et al., 2011 and Lee et al., 2006) or Cluster Analysis and Multidimensional Scaling

(Green, Parr, Breitmeyer, Valentin, & Sherlock, 2011). Charters and Pettigrew (2007) attempted to describe and evaluate the standard quality of wine based on a wide range of dimensions, some of which are difficult to measure and report, making their definition complex. Jover, Montes, and Fuentes (2004) divided the standard quality of wine into 15 dimensions divided into two clusters: eight extrinsic factors such as reputation, appellation, region, advertising and others factors and seven intrinsic factors related to physical features of the wine, such as age, color, chemical properties, aroma and harvest. Other studies evaluated the relationship between the extrinsic (Green et al., 2011 and Vázquez-Rowe

et al., 2012) GSK-3 beta pathway and intrinsic factors, in order to improve the quality of Vitis vinifera wines to a standard level ( Bindon et al., 2013, García-Carpintero et al., 2011, Ortega-Heras et al., 2010 and Parpinello et al., 2009). However, studies about the relationship amongst the intrinsic factors on Vitis labrusca wines are practically nonexistent, or restricted to an individual factor such as the chemical composition of the edible parts (flesh and skin) of Bordô grapes

( Lago-Vanzela, Da-Silva, Gomes, García-Romero, & Hermosín-Gutiérrez, 2011). Hence, the relationship amongst the 2-hydroxyphytanoyl-CoA lyase intrinsic factors comprises an interesting approach, allowing for the characterization of red table wines. Furthermore, American cultivars (Vitis labrusca) are responsible for about 80–85% of the volume of grape production in Brazil ( Nixdorf & Hermosín-Gutiérrez, 2010) and thus have a great influence on Brazilian wine production because of their nutritional effects. Scientific researchers have discovered that the habit of a daily intake of red table wine may be associated with longevity, due to the presence of resveratrol, which prevents the occurrence of cardiovascular diseases such as arteriosclerosis and thrombosis, controlling diabetes and reducing the risks of some types of cancer ( German and Walzem, 2000, Goldfinger, 2003, Pendurthi et al., 1999 and Wang et al., 2006).
