The Short Answer
Tej is a traditional Ethiopian fermented honey wine rich in antioxidants, primarily from honey polyphenols and gesho phenolics, which exert free radical scavenging activity. Its spontaneous fermentation by yeast and lactic acid bacteria produces organic acids and alcohol, contributing to its unique health-promoting profile.

Origin & History
Natural habitat
Tej is a traditional Ethiopian honey wine, a fermented beverage crafted from honey, water, and gesho (Rhamnus prinoides), a native bittering herb. Originating in Ethiopia, it is revered for its golden color and ceremonial significance. This unique fermentation process imbues Tej with probiotic richness, making it a functional beverage that supports digestive health and cultural vitality.
“Tej has been a treasured sacred and social elixir in Ethiopia for centuries, brewed by generations of women and served in traditional berele glasses. It symbolizes hospitality, abundance, and wellness within Ethiopian culture, particularly at weddings and religious festivals. This ancient Ethiopian fermentation tradition now bridges cultural heritage with modern functional nutrition, celebrating vitality.”Traditional Medicine
Scientific Research
Research from platforms like PubMed and ScienceDirect supports the probiotic activity and antioxidant properties of fermented honey beverages. Studies also explore the immune-supportive compounds present in honey-based drinks and traditional Ethiopian functional beverages. Further specific clinical trials on Tej itself would strengthen the evidence base.
Preparation & Dosage
Traditional preparation
Preparation
Mix honey and water (2:3 ratio), add crushed gesho leaves or stems, and ferment for 7–14 days.
Serving
Consume ½–1 cup per occasion, served chilled or at room temperature.
Storage
Best consumed within a few weeks of fermentation to preserve flavor and probiotic content.
Nutritional Profile
- Natural Sugars (glucose, fructose): Provide readily available energy.
- Vitamin C: Supports immune response.
- Probiotics: Enhance digestive balance and immune resilience.
- Antioxidants (from honey and gesho): Combat oxidative stress.
- Flavonoids: Offer anti-inflammatory and cardioprotective benefits.
- Polyphenols: Enhance antioxidant protection.
How It Works
Mechanism of Action
The primary mechanism involves potent antioxidant activity, evidenced by DPPH (37.9-81.0% scavenging) and ABTS (27.4-73.1% scavenging) assays, largely attributed to polyphenols from honey and phenolics from gesho (Rhamnus prinoides). Spontaneous fermentation by lactic acid bacteria (LAB) and yeasts produces organic acids like lactic acid, which contribute to gut microbiota modulation and potentially deliver probiotic effects. Furthermore, fermentation-activated polyphenols and gesho phytochemicals may exert anti-inflammatory actions.
Clinical Evidence
While in vitro and in situ studies have characterized Tej's antioxidant capacity (DPPH: 37.9-81.0% scavenging; ABTS: 27.4-73.1% scavenging) and identified its microbial composition, specific human clinical trials detailing its health benefits are limited. Research primarily focuses on its phytochemical profile, microbial communities (Saccharomyces, Zymomonas, Lactobacillus), and fermentation processes. Further controlled clinical investigations are needed to substantiate its purported probiotic, immune-supportive, and anti-inflammatory effects in human populations.
Safety & Interactions
Due to its alcohol content (6.36-11.34 g/100 mL), Tej should be consumed responsibly. Potential side effects include intoxication, impaired judgment, and coordination loss with excessive consumption. It is contraindicated during pregnancy, breastfeeding, for individuals under the legal drinking age, and those with a history of alcohol abuse or certain medical conditions like liver disease. Tej may interact with medications that have adverse reactions with alcohol, such as certain antibiotics, sedatives, or pain relievers; consultation with a healthcare professional is advisable.

Frequently Asked Questions
What gives Tej its probiotic properties?
Tej's probiotic properties come from the lactic acid bacteria (LAB) and yeasts (Saccharomyces, Zymomonas) involved in its spontaneous fermentation. These microorganisms contribute to its unique microbial profile and produce beneficial organic acids.
What is the alcohol content of Tej?
Tej typically has an alcohol content ranging from 6.36 to 11.34 g/100 mL. This level can vary depending on the specific fermentation process and honey concentration used.
What are the main antioxidant compounds in Tej?
The primary antioxidant compounds in Tej are derived from honey polyphenols and gesho (Rhamnus prinoides) phenolics. These compounds contribute significantly to its observed free radical scavenging activity, as measured by DPPH and ABTS assays.
Is Tej safe for everyone to consume?
No, due to its alcoholic nature, Tej is not safe for everyone. It should be avoided by pregnant or breastfeeding individuals, those under the legal drinking age, and individuals with liver conditions or who are taking medications that interact with alcohol.
How does gesho contribute to Tej?
Gesho (Rhamnus prinoides) leaves are crucial in Tej production, serving as a traditional bittering agent and a source of fermenting microorganisms. It also contributes phenolics and phytochemicals, enhancing Tej's antioxidant and potentially anti-inflammatory properties.
How does the fermentation process in Tej affect its probiotic potency compared to unfermented honey?
Fermentation in Tej transforms honey through microbial activity, generating live beneficial bacteria and organic acids that enhance digestive function far beyond what raw honey provides. The fermentation process breaks down complex honey compounds into bioavailable forms while creating an acidic environment that preserves probiotic viability. Unfermented honey lacks these fermentation-derived microorganisms and has minimal prebiotic activity, making fermented Tej significantly more effective for gut microbiota support.
Can Tej be consumed as a daily supplement, or should it be cycled periodically?
Tej can be incorporated into a daily routine as a traditional fermented beverage, though typical servings are modest (2–4 oz) due to its alcohol content and concentrated nutrient density. Many traditional cultures consume it regularly in small amounts rather than as a high-dose supplement. Cycling is not necessary if consumption remains moderate and aligns with individual tolerance, though periodic breaks allow the gut microbiota to naturally regenerate without constant external microbial introduction.
Does homemade Tej have different probiotic levels than commercially produced versions?
Homemade Tej fermentation times, temperature conditions, and wild fermentation variables can result in highly variable probiotic counts and strain diversity compared to standardized commercial products. Commercial versions often use controlled fermentation with specific starter cultures to ensure consistent CFU counts and documented microbial species. Homemade batches may offer superior strain diversity from native microorganisms but lack quality assurance regarding safety, potency, and contamination risk.
