Objectives
Currently, the assessment of phenolic maturity involves manual, lengthy and tedious methods.
In order to allow oenologists or viticulturists to follow the phenolic evolution of the grape in real time (on plot or regional level), it was necessary to convert the reference method into a routine analysis. The FT-IR method developed by FOSS (WINESCAN FT120), and combined with a rapid grape sample preparation technique, is an advantageous and viable analytical technique.
The quantitative, and possibly, qualitative data for polyphenols in Pinot Noir should contribute to the proper determination of harvest dates, and to guide the vinification.
The seasonal character of harvests limits winemaking considerably, especially oenological research. Thus, conserving sterile musts during the whole year to carry out experiments is certainly a very...
