Resumo(s)
The study of the evolution of wine components in four HDPE tanks for the five months of its aging was carried out, through three different types of HDPE and one kind of wood used: HDPE with low, medium and high permeability to oxygen and staves of French wood (Quercus petraea).
The HDPE tanks, which are permeable to oxygen, and the wooden staves that give their sensorial contribution, were used to simulate the wine ageing in barrels.
The tanks were compared to a steel tank to confront the evolution of the phenolic structure and color of wine during the months of aging.
The analysis of the wine was carried out on the colour, pigments and phenolic compounds (flavanols, flavonols, anthocyanins) by spectrophotometer; HPLC analyzes were also carried out to evaluate the content of catechins, procyanidins and anthocyanins monomers on the base wine.
The HDPE tanks could be a good alternative technology compared to the use of the barrels, which it allows to the wine to undergo a great aging and reducing the costs of aging in barrels, as the barrels have a higher cost than polyethylene tanks.
Probably, wine aging in HDPE tanks can complement the aging in barrique, in order to reduce the use of wood, as it is a limited resource on earth, while the polyethylene is recyclable
