What is Vegetable Tanned Leather? What are its Characteristics and Charms?

At Hallelujah, we have always used various types of leather, including Pull-up Leather rich in oils, to craft wallets and bags.
One of the beloved choices is Vegetable Tanned Leather. In this article, we aim to provide a simple and clear explanation for those interested in Vegetable Tanned Leather.

What is Vegetable Tanned Leather? Characteristics and Charms of Vegetable Tanning】

There are various terms, but "Vegetable Tanning" and "Vegetable Tanned Leather" refer to the same thing – the leather itself. Due to the use of "shibu" (tannins) during the tanning process, it is sometimes called "Shibu Tanning." As the term "vegetable" implies, the tanning agents extracted from plants, a method dating back to ancient times, contribute to a time-consuming and warm leather production process. Being made from natural materials, it is hailed as an environmentally friendly product.

Leather would deteriorate if not tanned. To prevent this, the animal hide is soaked in vegetable tanning agents, and tanning is carried out. The resulting tanned hide, now a commodity, is referred to as "leather."

 

What Plants are Used in Vegetable Tanned Leather?

Oak trees, which have a long history in Europe and North America, have over 150 plant varieties used globally.

Almost all parts of plants, including wood, bark, leaves, branches, fruits, and roots, contain tannins to protect them from biological harm. The discovery of using these plant components to protect leather undoubtedly changed the course of history. Initially ground into powder, these plant materials are now extracted in barrels and then used in the tanning process. Some main plants used include mimosa, acacia, chestnut, oak, and hemlock.

Exciting discoveries are anticipated as more plants rich in tanning agents are found in different regions.

What is Plant Tanning Agent?

Tannin is a polyphenolic compound found in plants, a bit complex in structure. It exists in plant tissues in the form of a solution. In the leather industry, it is called "tanning agent," while in food, it's referred to as "catechin" or "polyphenol."

Indeed, tea with polyphenolic compounds can taste bitter. Tannins are also common in our daily lives, found in chocolate, indicating that tannins have health benefits for both humans and leather.

 

In the brewing industry, oak barrels rich in tannins are used for beer and wine, enhancing their flavor. This suggests that tannins not only play a role in the leather-making process but also have other uses in our daily lives.

Key Points of Vegetable Tanned Leather to Understand:

  1. Nature of Leather: Tannin-tanned leather initially has a somewhat rigid texture, gradually softening with use, preserving the leather's inherent qualities, scars, and natural character, showcasing a unique texture.
  2. Aging: It tends to exhibit aging effects. The depth of aging changes depends on variations in tannins and oils within the leather. Vegetable Tanned Leather is prone to color changes due to exposure to UV rays and oxygen in the air, making color shifts more apparent.

3.Transition from Rigid to Soft:
Hallelujah's Vegetable Tanned Leather is exceptionally soft. Using thin and lightweight leather ensures both softness and density. Compared to other brands' Vegetable Tanned Leather (depending on the leather type, such as cow or horse leather), Hallelujah's leather is relatively thin and light, providing a softer and more comfortable feel during use.

    Who is Vegetable Tanned Leather Suitable For?

    Recommended Audience:

    • Those who enjoy the aging process of leather.
    • Individuals who can engage in regular maintenance.
    • Those who see the original flaws of leather as attractive.
    • Those who prioritize environmentally friendly products.
    • Individuals looking for long-term use items.

    On the contrary, for those who prefer easy maintenance and simplicity, it is recommended to use chrome-tanned products. Chrome-tanned products use a chemical called chromic sulfate, a tanning method developed in Germany.

    Recommended Audience for Chrome-Tanned Products:

    • Those who dislike the natural expressions of leather (such as flaws).
    • Individuals willing to engage in periodic maintenance but want to save time.
    • Those who prefer lightweight leather.

    Chrome-tanned products offer excellent water resistance and a soft texture. Due to their durability, they are mainly used in bags, shoes, sofas, etc. It is essential to note that chrome-tanned leather is less prone to aging changes.
