I recently discovered that October 1st is International Coffee Day, an occasion used to promote and celebrate coffee as a beverage. As a natural dyer, I enjoy experimenting with food to see the variety of colors and hues they produce; being that coffee stains are notoriously difficult to remove, I figured it could also substitute as an excellent dyestuff in the natural dyeing practice.
Coffee makes a good natural dye because it contains chemical compounds known as Tannins. Tannins are naturally found in a variety of plants including tree bark, leaves, seeds and spices. Plants produce them as natural defense against pests; tannins also contribute colour and an astringent, bitter flavour to the foods that contain them. Tannins easily bind to proteins so for this reason, it makes a great natural dye for my 100% Untreated BFL yarn that I will be sampling.
