In the intricate world of red winemaking, the process of skin maceration plays a pivotal role in extracting colour, flavour, and tannins from grape skins. While traditional maceration durations suffice for many wines, winemakers seeking to push the boundaries of intensity turn to extended skin maceration. We explore the art and impact of prolonged skin maceration, a technique that transforms red wines into robust, deeply hued elixirs with complex flavour profiles.

-What is Extended Skin Maceration?-

Skin maceration refers to the period during winemaking when the crushed grape juice remains in contact with the grape skins. This process is crucial for red wines, as it allows the extraction of pigments, tannins, and flavour compounds from the skins, contributing to the wine’s colour and structure.

Extended skin maceration takes this fundamental step to the next level by prolonging the contact between the juice and the skins. Instead of the typical one to two weeks of maceration, winemakers practicing the extended technique may extend this period to several weeks or even months. This prolonged contact intensifies the extraction of compounds from the skins, resulting in wines with heightened colour, pronounced tannins, and a more complex flavour profile.

-The Impact on Colour-

One of the most immediately noticeable effects of extended skin maceration is the deepening of the wine’s colour. The grape skins are rich in anthocyanins, the pigments responsible for the red, purple, and blue hues in red wines. As the maceration period lengthens, more anthocyanins are leached from the skins, intensifying the wine’s colour and creating a visually striking, opaque appearance.

-Tannin Structure and Texture-

Tannins, compounds found in grape skins, seeds, and stems, contribute to a wine’s structure and mouthfeel. Extended skin maceration enhances the extraction of these tannins, resulting in wines with a firmer, more robust structure. The increased tannin presence not only adds to the wine’s aging potential but also contributes to a fuller and more textured mouthfeel.

-Flavour Complexity-

Extended skin maceration goes beyond mere colour and structure; it delves into the realm of flavour complexity. The compounds responsible for a wine’s aroma and taste are abundant in grape skins, and the prolonged contact allows for a more complete extraction of these compounds. This can result in wines with a wide array of flavors, ranging from dark fruits like blackberry and plum to more nuanced notes of spices, herbs, and even floral undertones.

-Winemaker’s Touch-

The decision to opt for extended skin maceration is a deliberate choice made by winemakers, often influenced by the grape variety, vineyard conditions, and the desired style of the final wine. While the technique can enhance certain characteristics, it requires a skilled hand to balance the intensity of extraction without overwhelming the wine with overly astringent or bitter elements.


Extended skin maceration stands as a testament to the dynamic and versatile nature of winemaking. The decision to extend the maceration period is not taken lightly, as it requires a deep understanding of the grape variety, vineyard conditions, and the desired outcome for the wine. For enthusiasts seeking wines of heightened intensity, depth, and complexity, those crafted through extended skin maceration offer a unique tasting experience.
