This study analyzed the volatile composition and aroma profile of BRS Carmem and BRS Violeta red wines elaborated from traditional and two alternative winemaking procedures: grape pre-drying and submerged cap. The wines contained higher concentration of acetates (ranging from 303 mg L-1 to 905 mg L-1) and Et and Me esters (ranging from 138 mg L-1 to 415 mg L-1). The BRS Carmem wines were described as fruity due to the higher concentration of esters and BRS Violeta wines were described as vegetal mainly due to the higher concentration of terpenes and methoxyphenols. C6 alcs. also influenced the vegetal notes of BRS Violeta wines from traditional and submerged cap procedures and the pre-dried wines also presented a relevant jam note possibly due to the presence of 2-phenylethyl acetate. The changes in winemaking procedures can possibly lead to changes in the aromatic profile of red wines in a pos. way, improving the wine aroma quality. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1HPLC of Formula: 2380-78-1).
4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.HPLC of Formula: 2380-78-1
