Reference: Comparative study of aromatic and polyphenolic profiles of Croatian white wines produced by cold maceration
Key Statements

Abstract-

Aroma profiles and phenolic components of white wines made from Pošip and Škrlet (Vitis vinifera L.) both native Croatian, non-aromatic grape varieties enhances the knowledge about these varieties, prepared without maceration (control) and subjected to the pre-fermentative cold maceration (CM). Individual phenolic compounds in wines were determined by high-performance liquid chromatography (HPLC) system, while total phenolics and flavan-3-ols in wines were determined by spectrophotometric methods. CM had the significant impact on the total phenolic and flavan-3-ols composition of Škrlet wine. The significant increase of some individual phenolic compounds was observed in Pošip wine. Volatile aroma compounds in wines were determined by gas chromatography (GC) with the previous extraction on the solid phase micro extraction (SPME). The primary aroma compounds, i.e. terpenes were under the significant influence of CM process in Škrlet wine. Aroma profiles, based on the content of 24 specific compounds, grouped in eight aroma series that contribute to wine odor were developed. CM significantly increased five aroma series in Škrlet wine and only three in Pošip wine.
