What is Vegetable Tanned Leather?

Vegetable-tanned leather is made using natural tannins found in organic materials to add a unique look and feel to the animal hide. Harmful chemicals are avoided.

We love using this kind of leather in our range, including for our popular leather journals and leather gifts.

While the names may sound similar, vegetable-tanned leather is not to be confused with vegan leather, which is not a real leather product at all.

To better understand how vegetable-tanned leather differs from other types of leather products, it’s important to know how it’s created. So we're going to dig deep into the leather tanning process.

How is Vegetable-Tanned Leather Made?

Vegetable-tanned leather is made by submerging animal hide in a water or saltwater solution. This removes the fur and makes the hide flexible. Vegetable-based oils and waxes are then applied for a tender, malleable finish.

The Leather Tanning Process

Vegetable-tanned leather begins immediately after an animal is slaughtered. The "green" or new hide is salted to preserve it then hung in a structure called a beam-house.

From there, the hide is moved to a liming pit where it is immersed in a natural chemical substance called lime to remove the hair from the hides through dissolution.

Hides are then placed in a vat containing tannin — in this case, natural tree bark or other organic materials. This soaking process helps to dehydrate the leather, contributing to softness and a nice hand feel.

The vegetable tanning process is a long and artisanal one, taking up to two months to complete, which is why leather is more commonly tanned with minerals like chromium.

 

Why Vegetable-Tanned Leather is Preferred

While chromium or chrome-tanned leather is cheaper to produce, and the colors stay constant for longer, vegetable-tanned leather has the longevity and beauty only an artisanally-crafted product can sustain.

Chrome-tanned leather often has its edges treated with acrylic varnish, causing it to crack, peel, and split after just a few years. In addition, the mineral chromium is a heavy metal and as such is quite toxic to the environment as well as to the people processing it.

The long, slow traditional techniques used to process the hides for vegetable-tanned leather means that vegetable-tanned leather goods continue to soften and develop a beautiful patina as they age.

For items made from vegetable tanned leather include saddles, holsters, belts, wallets, journal covers, bags, shoes, and purses, this means they will become even more comfortable the longer you use them. The edges of vegetable-tanned leathers are burnished or turned, meaning this leather is created to last for decades. Usually, this kind of leather is stiff in the beginning but gets more supple with time and use. 

Also, vegetable-tanned leather has that distinctive “leather” aroma, rather than the typical chemical odor of chromium-tanned goods. The fragrance is sweet, woody, and rich.

Also, the natural leather tanning process leaves the leather with unique variations in shade and color.

The original fibers of the animal’s hide can easily be seen, adding to its character. A piece of vegetable-tanned leather is truly a one-of-a-kind product.

Finally, owing to its artisanal nature, the vegetable tanning process produces some of the sturdiest, most durable leathers available. It’s a much less pliable product than chromium-tanned leather, so it’s used where stiffness can be an asset, such as saddlery, holsters, wallets, journals, travelers notebooks, and handbags. Due to the artisanal nature of the tanning process, Vegetable-tanned leather is more expensive than chrome leather. It’s usually used for high-end handmade leather goods.

However, it does get wonderfully soft and pliant over time, so many manufacturers create shoes, bags, belts, and other long-lived products using this material.

While this method of tanning does use quite a bit of water, it does not pollute the environment the way the chromium-based leather tanning process does. There is also less machinery, and so less electricity, involved with the vegetable tanning process.

Undyed Vegetable Tanned Leather Aging

When you get your brand new undyed vegetable-tanned leather good, it looks a natural color. The hide is effectively naked and so will age and darken with the sun just like your own skin. Aging will continue to darken your leather. Normal wear will darken the leather as air, light, the oils of your skin, and other environmental factors do their work, eventually developing a rich color and patina. Sun exposure, daily handling, water, and conditioning give natural vegetable tanned leather a rustic look over time. Learn how to condition leather here.

The aging process of leather takes time. After a while, you’ll be rewarded with a gorgeous patina that makes your product one-of-a-kind. Patina development depends on what type of product you have and how you use it – a small, natural vegetable tanned leather wallet may age much more quickly than a large leather bag that isn’t used and handled as much. You can speed up the aging process if you’re impatient to see results. Using a natural leather balm or more exposure to the sun will darken your leather.

FAQ'S

+How to identify vegetable tanned leather?

Here are some simple tips for identifying the tanning method used for a sample of leather.
Wet a piece and then stamp a mark into it. If the mark has a crisp impression afterward, the leather is vegetable tanned. If the impression is just discernable, it is chrome tanned. An easy way to test whether leather is 100% vegetable tanned is to drop a small strip of the leather into boiling water (be careful). If it is 100% vegetable tanned it will instantly shrink and curl up like a worm. If it doesn't other tanning agents have been used in tanning the leather. Chrome tanned, undyed leather is a pearl grey with a faintly bluish tint. Dyed chrome tanned leather often retains a grey-blue or white center core. Beware of chrome tanned leather for knife sheaths - it can corrode the metals.
