Does harvesting harm the trees?

Done responsibly, no — growers avoid over-tapping and give trees time to recover between seasons.

Is mastic biodegradable?

Yes — it is a 100% natural resin, unlike synthetic gum made from a plastic base.

What protections does Chios mastic have?

It holds PDO (Protected Designation of Origin) status, and the cultivation know-how is on UNESCO's Intangible Cultural Heritage list.

Is Chios Mastic Gum Sustainable?

Q: Is Chios mastic sustainable?

Yes — it is hand-harvested with care so trees recover, supported by local communities and regulation, and the know-how is UNESCO-protected.

In short: yes — Chios mastic is considered sustainable. It's hand-harvested by small, careful incisions that let the trees recover, supported by local communities and regulation, and the know-how is even protected as UNESCO Intangible Cultural Heritage.

We've introduced the island of Chios, its mastic trees and how mastic is harvested. So is it sustainable? Here are five reasons it is.

1. Harvesting practices

Mastic is obtained by making small incisions in the bark of the mastic tree (Pistacia lentiscus var. Chia) so the resin oozes out and forms tears that are later collected. Responsible harvesting means avoiding over-tapping and giving the trees enough time to recover between seasons.

2. Cultivation initiatives

Cultivating mastic trees helps meet demand without putting excessive pressure on wild populations. Managed groves allow for more sustainable, long-term care of the trees.

3. Community involvement

Mastic-producing villages involve local communities throughout the harvest, with education and fair compensation for growers. That shared stake helps preserve the mastic-tree ecosystem for the future.

4. Regulatory measures

Harvesting is controlled to keep practices sustainable, prevent over-harvesting and protect the natural habitat — part of why genuine Chios mastic carries PDO status.

5. Environmental impact

Sustainable harvesting also considers the wider environment: preserving the region's biodiversity, maintaining soil health and avoiding deforestation. And because mastic is a natural resin, it's biodegradable — unlike synthetic chewing gum.
