On the southern tip of the Greek island of Chios, something extraordinary happens every summer. Farmers score the bark of small, gnarled trees with a metal tool, and the trees weep.

The tears are translucent, crystalline, and smell faintly of pine and cedar. They harden in the Mediterranean air into small, irregular crystals that have been collected, traded, and treasured for over 2,500 years. The ancient Greeks called them the tears of Chios. Today we call them mastiha.

Mastiha is one of the most unique ingredients in the world. It grows nowhere else — attempts to cultivate mastic trees outside southern Chios have consistently failed to produce the resin. The combination of soil, climate, and microclimate of that specific corner of one Greek island is irreplaceable.

What Is Mastiha?

Mastiha (also spelled mastic, from the Greek mastichein — to chew) is a natural resin produced by the mastic tree (Pistacia lentiscus var. Chia). The trees are cultivated in the mastichochoria — the "mastic villages" — of southern Chios, a cluster of medieval fortified villages built specifically to protect the crop from pirates.

The harvest process has not changed in centuries:

1. In late June, farmers clean the ground beneath each tree and spread white calcium carbonate powder
2. They score the bark with a special tool, making small incisions
3. The tree weeps resin, which drips onto the white ground and hardens into small crystals
4. In August and September, the crystals are collected by hand, cleaned, and sorted

Each tree produces only 60–180 grams of mastiha per year. Total annual Chios production is roughly 150 tons — a tiny quantity for a globally recognized ingredient.

A History Spanning Millennia

Mastiha is one of the oldest documented commodities in human history. Hippocrates prescribed it for digestive complaints. Ancient Egyptians used it in embalming. The Romans imported it from Chios at considerable expense.

The word "masticate" — to chew — comes directly from mastiha. It's considered the world's first chewing gum, chewed by Greeks and Romans for fresh breath and digestive comfort long before modern gum existed.

During the Ottoman period, Chios mastiha was valuable enough that the mastic villages received special tax protections from the Sultan. Today, Chios mastiha carries PDO (Protected Designation of Origin) certification — it's the only mastiha in the world with this status, and the only place it's legally produced.

What Does Mastiha Taste Like?

• Initially: Resinous, slightly bitter, with notes of pine and cedar
• As it warms: A subtle sweetness emerges, with hints of eucalyptus and fresh herbs
• The finish: Clean, fresh, and lingering

In cooking, mastiha adds a subtle aromatic complexity that's hard to describe but immediately recognizable — a background note of something ancient and distinctly Mediterranean.

Traditional Uses: What Greek Cooks Do With It

Mastiha comes in small, irregular crystals that are typically frozen for about 30 minutes, then ground with a pinch of sugar to keep the resin from clumping as it warms from the friction of grinding.

Sweet Applications

• Tsoureki — Greek Easter bread. Mastiha is one of the traditional flavorings that give tsoureki its distinctive aroma
• Kaimaki — traditional Greek ice cream flavored with mastiha and salep; famously stretchy and aromatic
• Cookies and pastries — a subtle resinous note in shortbread, biscotti, or baklava
• Custards and puddings — a pinch adds complexity to rice pudding
• Liqueur — Mastiha liqueur from Chios is one of Greece's distinctive spirits

Savory Applications

• Lamb and goat — a traditional pairing in Greek and Middle Eastern cooking
• Rice dishes — a pinch in pilaf adds aromatic depth
• Bread — traditional Greek village bread often includes mastiha
• Cheese — mastiha-flavored cheese is produced on Chios and pairs well with honey

As a Chewing Resin

The most traditional use: simply chew a few crystals. This is how Greeks have used mastiha for centuries — for fresh breath, digestive comfort, and the simple pleasure of the flavor.

What's Being Studied — and What We're Not Claiming

Mastiha has a long folk-medicine history, and some modern research has explored its properties — including studies on antimicrobial and anti-inflammatory activity. However, this research is ongoing and not conclusive, and mastiha is a food ingredient, not a treatment. We're not making health claims about mastiha here, and if you're considering it for a specific health condition, talk to a doctor first.

Mastiha in Greek Culture

In Chios, mastiha is not just an ingredient — it's an identity. The mastic villages (mastichochoria) are recognized for medieval architecture built specifically around the mastiha economy, including the geometric xysta patterns found nowhere else in the world. The Chios Mastiha Growers Association, founded in 1938, controls production and quality, and every gram of authentic Chios mastiha is certified and traceable.

A Note on Availability

Mastiha isn't currently part of our catalog — it's a specialty ingredient that's genuinely hard to source authentically, and we'd rather tell you that honestly than list something we can't stand behind yet. What we do carry from the same island's tradition: Hellenic Farms, founded in 2013 by Vivianna Karamanis and certified 100% woman-owned, draws on its own Chios family heritage for the olives and spreads in our collection — a real taste of the same island this story comes from.

Frequently Asked Questions

Where does authentic mastiha come from?

Exclusively from the mastic villages of southern Chios, Greece — it carries PDO certification and cannot be legally produced or labeled as mastiha anywhere else.

Does mastiha have health benefits?

Mastiha has a long folk-medicine history and is the subject of ongoing scientific research, but it is a food ingredient, not a medical treatment. We don't make health claims about it, and anyone considering it for a health condition should consult a doctor.

Do you sell mastiha?

Not currently — it's a genuinely hard ingredient to source authentically, and we'd rather be upfront about that than sell something we can't verify. If you're drawn to Chios' food traditions, our Hellenic Farms products carry that same island heritage.
