Acacias have been used as a source of tannins since the times of ancient Egypt. Acacia nilotica is also known as Egyptian Mimosa. Our Mimosa comes from Acacia mearnsii (also know as black wattle) it is cultivated extensively for this purpose and is one of the world’s most important sources of vegetable tannin. It is heavily used in the leather tanning industry. Mimosa is a catechic or red-brown tannin like quebracho and cutch. It will impart a light peach colour when used as a tannin at the recommended strength of 8-10 % WOF.
