Grape Seed Extract
Source: White Grape Seeds (Vitis Vinifera L.) | Grape Seed Extract from Occitania

Grape Seed Extract is a 100% natural dye made from the seeds of white grapes, upcycled from the by-products of the wine-making industry. Produced sustainably through a water-based extraction process, this extract supports circular economy principles, offering an eco-friendly option for textile dyeing and beyond.

Main Components:

  • Condensed Tannins > 70% (catechin equivalent)
  • Eco-friendly, upcycled product
  • Water-extracted for minimal environmental impact

Suggested Quantities (WOF - Weight of Fabric):

  • Light Shades: Use 5–10% WOF for soft, pinky-beige hues (without mordant).
  • Medium Shades: Use 10–15% WOF for more intense colour.
  • Dark Shades: Use 5–20% WOF and combine with mordants such as iron for darker tones like grey.

Uses:

  • Natural Dye & Textile Printing: Suitable for all types of fibres, whether mordanted or not. Typical shades depend on the recipe and mordant, including pinky-beige (no mordant), grey (with iron), and orange (with titanium). The extract is registered as "metal-free" and provides good lightfastness.
  • Other Uses: Ideal for tannery processes, antioxidants, and more.

The Plant:
The vine (Vitis vinifera) is a woody, climbing plant, known for its long stems that can grow up to six metres. Its small flowers are greenish-white, and the fruits are grape clusters. Grapes have been cultivated for thousands of years in Europe, western Asia, and northern Africa. They are used for fresh eating, drying as raisins, or fermentation to produce wine.

Upcycling of By-products:
Grape Seed Extract is produced through the upcycling of wine industry by-products, contributing to circular economy practices. The wine industry offers a wealth of natural ingredients such as wines, juices, concentrates, and polyphenols, while minimizing waste through innovation and new technologies. The producer is located in the heart of the South of France’s vineyard region and proudly contributes to this sustainable bio-economy.

Recipe for Dyeing with Grape Seed Extract:

Ingredients:

  • Grape Seed Extract (use WOF formula)
  • 1 litre of water to dissolve (adjust based on the amount of fabric)
  • Pre-mordanted fabric (cotton, wool, silk)
  • Optional: Iron modifier for grey tones

Instructions:

  1. Dissolve the Grape Seed Extract in warm water, stirring well until fully dissolved.
  2. Add pre-mordanted or not mordanted fabric to the dye bath.
  3. Heat the fabric in the dye bath for 45–60 minutes, stirring occasionally, leave overnight (optional).
  4. Rinse thoroughly in cold water and dry in the shade.
  5. Optional: For grey tones, dip the dyed fabric in an iron modifier bath.
