Tannin is mixed with rain or other types of soft water because minerals will react to the tannic acid, resulting in ugly blemishes. This is why the first tanneries in ancient Egypt were located near the Nile River, because substantial amounts of water was needed for liming, soaking, and production.
Our tanneries are exceptionally diligent in this process and provide us with the utmost consistency in leather hides. Hides are then places inside large drums that rotate at approximately 6 RPM to evenly distribute the dye. The larger the hide, the more tannin is required as it absorbs the liquids.
Temperature of the liquids is also critical because it affects the color saturation of leather. Hot water can darken the tannin, while cold water enchants leather with the lightest color. Our tanneries are located in the district of Santa Croce sull'Arno in Tuscany, one of the leading areas of leather production since the mid-19th century. Today, 35% of Italian leather production and nearly 95% of leather soles are produced in this area for an annual turnover of over 2 billion. In 2010, Italian leather production accounted for 16% of world production and nearly 70% within the European Union.
