Wine aging

30 Outubro 2020, 14:30 Sofia Cristina Gomes Catarino

Wine aging: wooden and vat/bottle aging.

Phenolic reactions (colouring matter and tannins) in red wine involving oxygen during aging.

Emerging technologies: micro-oxygenation, wood fragments, oak alternatives, permeable tanks, added tannins.
