Chios, Greece Mastic has been coming from this island for over two thousand years due to its trading history, empires and determination of family farmers. Its resin was celebrated by ancient writers, its economy built by medieval rulers and its name protected by modern law. Every tin of mastic we sell at Titans Jaw starts with that story.

How far back does the story of mastic in Chios, Greece go?
It dates back to at least 2,500 years ago. In fact the trees are much older! So if you’re asking about the history of Mastic in Chios Greece then the truth is it dates back prior to written history.
The official EU product specification for Chios mastic lays out the long view:
- Fossil leaves around 6 million years old have been found on the island, according to geologists cited in the specification.
- Herodotus, writing in the 5th century BC, refers to Chios mastic.
- Greek physicians such as Hippocrates and Dioscorides knew its uses.
- Travellers spread its fame from around the 1st century AD.
So anyone searching mastic chios greece is looking at one of the oldest traded products still made in the same place, in much the same way. Very few products available to purchase online have such a rich history. Even the English word for chew (masticate) comes from the same Greek roots as mastic due to its long history of being chewed, however nice the pack looks. Our guide to the difference between small and medium mastic tears goes deeper on tear sizes.
How did mastic shape Chios under Genoese and Ottoman rule?
Mastic made Chios worth fighting over and worth protecting. Of course, whoever had control over the island also had control over one of the most precious resins from the Mediterranean and thus the mastic producers were well looked after.
During the period of Genoese rule (14 th-16 th centuries) when the island was controlled by a trading company, the mastic trade became very regulated. The villages which grew it were heavily fortified with houses built together to form defensive blocks. Many are still like this today meaning you can walk along the same lanes as the growers did centuries ago.
The Ottomans then took over and mastic remained in great demand from 1566. According to Greek News Agenda, the Greek government’s official news service, the villages where the mastic tree grows were given special privileges and certain freedoms under both Genoese and Turkish control. Local tradition also holds that the mastic villages were largely spared during the 1822 massacre on Chios, because of their value to the empire.
Finally, Chios joined modern Greece in 1912. By then, mastic was woven into the island’s identity, and it still is today.
Which milestones protect Chios mastic today?
The product is protected by several modern regulations; a growers co-op, EU legislation and UNESCO status. These have also made the local tradition a protected area of origin so that the name now has meaning.
| Year | Milestone | Why it matters |
| 1938 | Chios Gum Mastic Growers Association founded | Growers began collecting and marketing mastic together |
| 1994 | Name protected in Greece | “Masticha Chiou” became a protected Greek name |
| 1997 | Registered as an EU Protected Designation of Origin | The name became protected across the European Union |
| 2014 | Added to UNESCO’s intangible heritage list | The know-how itself was recognized, not just the product |
| 2016 | Chios Mastic Museum opens in Pyrgi | The history got a permanent home on the island |
For example, the EU step is recorded in Commission Regulation (EC) No 123/97, which registered Masticha Chiou as a PDO in January 1997. Interestingly, the same regulation also protected “Tsikla Chiou,” the island’s traditional mastic chewing gum. Under the product specification, official PDO labels also carry a serial number and the last two digits of the production year.
How does mastic hold Chios communities together?
Mastic holds communities together because growing it is a family job that runs all year, with every generation involved. In short, it’s as much a way of life as a crop.
UNESCO’s listing for the know-how of cultivating mastic on Chios describes it as a family occupation needing careful work year-round. All ages are able to take part equally and those who have grown older teach younger generations how to score the bark and collect the tears. During the busiest times they will help each other and maintain traditional stories and customs. This has helped the tradition survive as the younger generations move into cities.
So if you’re wondering what makes Chios special for mastic, the soil and climate are only half the answer. The other half is people who’ve done this for centuries. Our guide on how Chios mastiha is harvested walks through the work season by season.
What else is Chios island known for?
The island of Chios is famous for more than just mastic! Medieval monasteries, citrus groves and painted villages can be found on this vast, diverse island. There’s something for everyone to enjoy regardless of whether they ever taste a drop!
A few highlights:
- Nea Moni, an 11th-century monastery in the hills, listed by UNESCO as a World Heritage Site alongside Daphni and Hosios Loukas.
- Chios Town, with its old castle quarter and busy harbour.
- Kampos, a plain of walled stone mansions and citrus groves just south of town.
- Chios mandarins, protected in the EU as “Mandarini Chiou.”
- Mastiha liqueur, sweets and breads, which you’ll find in cafés across the island.
However if you do visit then the Chios Mastic Museum provides the best insight into how the resin has impacted life on the island. The museum is located within the mastic groves giving visitors a chance to see the trees.

Of course, a few questions come up all the time. Where is Chios in Greece, and why is mastic only from Chios? People also ask what the mastihochoria are, and why does mastic only grow in Chios Greece rather than elsewhere. You’ll find short answers in the FAQs below, including a look at the mastic villages themselves.

Frequently asked questions
1. Where is Chios?
The island of Chios is located in the North East Aegean Sea just off the West Coast of Turkey. It is the 5 th largest island in Greece and can easily be accessed by taking the ferry or flying from Athens. The area where the Mastic grows is located on the South side of the island and the main town and port are located on the East Coast. The island is only a few km away from the Turkish mainland.
2. Why only there?
Mastic comes only from southern Chios because the right tree, soil, climate and know-how all meet there. The local variety, Pistacia lentiscus var. Chia, grows in a mild, dry microclimate with particular soils. Greece’s national inventory of intangible heritage notes that attempts to produce mastic in northern Chios and elsewhere have failed. On top of that, generations of local growing skill matter just as much as the land.
3. What are the mastic villages?
The mastic villages, or Mastihohoria, are 24 villages in southern Chios where mastic is produced. They include Pyrgi, Mesta, Olympoi, Vessa, Armolia, Kalamoti and Lithi. Many still keep their medieval layouts, because the tightly packed stone houses were built for defence. Pyrgi is known for its black-and-white patterned walls, and Mesta for its maze of narrow lanes.
4. Can mastic grow elsewhere?
The mastic shrub grows across the Mediterranean, but it doesn’t produce Chios-quality mastic anywhere else. Attempts outside southern Chios haven’t produced comparable resin in useful amounts. Besides, EU law limits the protected name “Masticha Chiou” to mastic from the 24 mastic villages. So resin sold as Chios mastic should only ever come from there.
5. Does origin change the chew?
Yes, origin matters, because genuine Chios mastic softens into a smooth, pliable chew with a fresh, pine-like flavour. However, blends or resins from other sources can crumble, taste harsh or stay gritty. Within Chios mastic itself, tear size changes the chew most, with small tears softening fastest and larger ones giving a firmer workout.
