Vegetable-tanned leather is often considered high quality due to several factors:

1. Durability: It is known for its strength and durability, making it suitable for long-lasting products like bags, shoes, and belts.

2. Eco-friendliness: The tanning process uses natural tannins from plants, which is more environmentally friendly compared to chrome-tanning methods.

3. Sustainability: Vegetable-tanned leather production often involves traditional craftsmanship and can be part of a sustainable production cycle.

4. Aesthetic Appeal: Over time, vegetable-tanned leather develops a unique patina, which many people find appealing. This patina adds character and a sense of history to the leather goods.

5. Workability: It is easier to work with for crafts like carving, tooling, and dyeing due to its absorbency and the ability to take a finish well.

6. Historical Significance: It has a long history and is associated with traditional leatherworking techniques, which adds to its appeal for many consumers.

However, whether vegetable-tanned leather is considered “high quality” can also depend on personal preferences and the specific use case. Some people might prefer the softness and flexibility of chrome-tanned leather for certain applications, such as clothing or upholstery. Additionally, vegetable-tanned leather can be more prone to water damage and may require more maintenance to preserve its condition.

In summary, vegetable-tanned leather is often seen as high quality due to its durability, eco-friendliness, and unique characteristics, but the perception of quality can vary based on individual needs and preferences.
