Skin contact refers to the period during which grape juice remains in contact with grape skins. Extended skin contact is the primary mechanism for extracting colour, tannin, and flavour compounds. In red wine, skin contact typically lasts through the entire fermentation (10–30 days). In white wine, brief skin contact (a few hours) can add colour and aromatic complexity (resulting in orange or amber wines). In rosé, controlled skin contact of 2–24 hours determines the final colour intensity. Managing skin-contact duration is critical to achieving desired colour, tannin, and flavour profiles.
WHY IT MATTERS FOR COLLECTORS
Extended skin contact in reds yields deeper colour, firmer tannins, and greater complexity. In white wines, brief skin contact produces distinctive aromatic profiles prized by collectors seeking unusual, age-worthy whites.
