Croatian barrels are traditionally made of the oak wood from the region of Slavonia, but its influence on wine quality has not been explored scientifically. This paper is a first investigation of Croatian barrique barrels and their influence on wine quality. Chardonnay and Sauvignon musts were fermented in new light and medium-toasted Croatian barrique barrels (225 l) and in steel tanks of the same volume. Chemical analysis of phenolic acids and phenolic aldehydes were made by HPLC just after fermentation. The wines were sensory tested by the descriptive method and the O.I.V./U.I.O.E. method by 100 positive points. The concentrations of phenolic compounds varied in the wines compared. Sauvignon wines generally had some higher total quantities of phenolic acids when compared with Chardonnay wines. Our results indicated that sensorial characteristics of produced wines were modified, probably due to the wood-derived compounds. (We recommend that you consult the full text article.

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...
This study aims at exploiting an undervalued winemaking by-product, wine yeast lees, by developing efficient and food-grade methods for the extraction of yeast glycoproteins. These extracts were th...

Aging on lees (AOL) is a powerful technique to protect varietal aroma and color, but it is a slow process. The use of ultrasounds (USs) is an alternative technology to break the yeast cells and to ...
Shelf-life is a very generalized notion that encompasses a lot of areas of wine quality, wine distribution and wine commerce. Shelf life is a projection, it’s something that happens in the future. ...

In this work, seven tannins with different botanical origin were characterized for the polyphenolic content and antioxidant capacity with a multitechnique approach, aimed at investigating the corre...
