Skin Contact White Wine Category

In the past decade, skin contact white wine, or amber wine / white wine with maceration, has gained increasing attention by media, sommeliers and wine lovers. In November 2020, the prestigious International Organisation for Vine and Wine (OIV) added an 8th category to their official list of wine styles: white wine with maceration

HK IWSC Skin Contact White Wine Category is a celebration of this global trend, and a recognition for winemakers who embrace this traditional winemaking technique and promote the wines to the world.

What is Skin Contact White Wine?

The term skin-contact wine refers to white wines that are fermented briefly – or entirely – with their grape skins hovering in the juice. Though the term is typically applied only to white wines, in truth, red and rosé wines are also skin-contact wines.  The concept of skin-contact wines is ancient, but the terms used to describe the process are relatively new and include:  skin-fermented wine, skin-maceration wines, orange wines, white wines with maceration, amber wines and a few more.

Like tea leaves in a teapot, the longer the grape skins rest with the juice, the deeper the colour, the more concentrated the flavour and the more tannic the texture of the final wine. A white wine's period of skin contact runs the gamut and depends upon the winemaker’s philosophy. For example, during Georgian traditional winemaking, grape skins mingle with the juice throughout fermentation and linger afterwards for 3-6 months.  The period of contact between the juice, skins and seeds during maceration has a significant impact on the composition and sensory characters of the resulting wine.

Amber Wine Around the World

Georgia’s amber wines have influenced winemakers around the world, especially within natural wine community. We can now see more and more skin contact wines from almost every winemaking countries, such as Italy, France, Spain, Portugal, Austria, Slovenia, Australia, South Africa, USA and Canada.

White wine derived from alcoholic fermentation of a must with prolonged contact with grape pomace, including skins, pulp, seeds and eventually stems.


  • Winemaking is conducted exclusively using white grapes varieties;
  • the maceration is carried out in contact with grape pomace;
