The short answer is yes, laphet contains caffeine, and quite a bit of it. Laphet, also spelled lahpet, refers to the pickled and fermented tea leaves that are the star ingredient of the national Burmese dish, laphet thoke, or tea leaf salad. Unlike brewed tea, where the leaves are steeped and removed, the entire leaf is consumed when you eat laphet. This leads to a more concentrated dose of caffeine and a distinct, longer-lasting energy boost that many people find stimulating and pleasant.
Why Laphet Contains Caffeine
Laphet is made from the leaves of the Camellia sinensis plant, the same plant used to produce black, green, and oolong tea. All leaves from this plant naturally contain caffeine. The difference lies in how the caffeine is ingested and metabolized. When you drink brewed tea, some of the caffeine is extracted into the hot water, and the leaves are discarded. With laphet, however, the whole leaf is consumed, so you get the full dose of caffeine along with all the other compounds in the leaf.
The Fermentation Process and Caffeine
Contrary to a common misconception, the fermentation process does not remove caffeine from the tea leaves. In fact, one study on microbial fermentation in tea leaves suggested that the caffeine content could actually increase under certain conditions. For laphet, the process involves a series of steps before and during fermentation:
- Harvesting: Young, tender tea leaves and buds are handpicked.
- Steaming: The leaves are briefly steamed to stop enzymatic oxidation.
- Rolling: They are rolled to bruise the leaves and prepare them for fermentation.
- Pressing: The leaves are packed tightly into containers and pressed with weights to create an anaerobic environment for fermentation, a process that can take weeks or months.
How Much Caffeine Is in Laphet?
While the exact caffeine content can vary depending on the tea leaves used and the fermentation time, research indicates a significant amount. A Reddit user citing a Science Direct article mentioned that laphet has approximately 3 mg of caffeine per gram. A typical restaurant serving of laphet thoke might contain 30-40g of the tea leaf dressing, which translates to a maximum of around 120mg of caffeine. This is comparable to a standard 8-ounce cup of coffee.
Laphet vs. Brewed Tea vs. Coffee: A Caffeine Comparison
| Item | Serving Size | Estimated Caffeine (mg) | Absorption Speed | Notes |
|---|---|---|---|---|
| Laphet (Fermented Tea Leaves) | 30-40g serving | ~90-120 mg | Slow, sustained | Consuming the whole leaf provides a long-lasting buzz. |
| Brewed Coffee | 8 oz cup | ~95-165 mg | Fast | Quick energy spike, often followed by a crash. |
| Black Tea | 8 oz cup | ~40-70 mg | Medium | Varies based on brewing time and leaf type. |
| Green Tea | 8 oz cup | ~20-45 mg | Medium | Generally lower caffeine than black tea. |
The Stimulating Effect of Laphet
The distinctive "caffeine kick" from eating laphet is well-documented. In Myanmar, the energizing effect is part of its cultural significance, with students eating it to stay awake for late-night study sessions and others enjoying it during long social events. Because the caffeine is bound within the tea leaves, it is released more slowly as the leaves are digested, leading to a gentle, sustained buzz rather than the intense, rapid jitters that can accompany a strong cup of coffee. This slower absorption is key to the unique experience of eating tea leaves.
Potential Side Effects and Considerations
While many enjoy the energy boost, the caffeine in laphet can cause some side effects, especially for those who are sensitive. Eating it too late in the evening may interfere with sleep. High caffeine intake can also lead to symptoms like headaches, jitters, and a rapid heartbeat in susceptible individuals. As with any food, moderation is recommended, and if you are sensitive to caffeine, it is best to enjoy this dish earlier in the day.

Conclusion
In summary, laphet unequivocally contains caffeine derived from the tea leaves from which it is made. Its fermentation process does not strip it of this natural stimulant. As a result, consuming this delightful Burmese salad provides a unique, sustained, and energizing effect that has made it a beloved delicacy for centuries. It is an excellent example of how the same base ingredient can offer completely different experiences depending on its preparation.
