Abstract
This study provides specific information about the influence of storage in bottle and in 225-L barrels made from oak (new and used for 1 year) and chestnut wood on color indexes, spectrophotometric evaluable polyphenols, anthocyanins, phenolic acids and gustative attributes of three monovarietal red wines (Piedirosso, Cabernet Sauvignon and Merlot). The results of the analysis of variance show that wood type has a significant influence on chromatic characteristics, on vanilline reactive flavans, on low molecular weight phenolics and on astringency of wines. The effect depends on the type of wine. Therefore, both traditional and alternative wood containers could be used as an instrument to regulate the polymerization, oxidation and copigmentation reaction of wine phenolics and the sensory properties of red wine. The maturation in chestnut wood could be an interesting challenge to widen the supply of red wines maturated in wood, but its use needs more care than oak.
