Chinese tea bricks: history, manufacturing, and centuries-old use as currency and medicine along the Silk Road.

About this subject

Tea bricks (茶砖, chá zhuān) are compacted blocks of compressed tea originating in China, particularly from Yunnan, Hunan, and Hubei provinces. Their production dates back to the Tang dynasty (7th, 9th centuries), when tea was pressed into bricks to facilitate transport along the Silk Road. These blocks were often used as currency for trade between Chinese merchants and Central Asian peoples, such as the Mongols and Tibetans.

The manufacturing process involves steaming tea leaves, grinding them, and pressing them into molds under high pressure, forming blocks that can range from 100 grams to several kilograms. The most common bricks are made from black tea (shou puer) or green tea, but aged varieties also exist and increase in value over time. During the Ming dynasty, pressed tea was essential for trade with Tibet, where it was consumed as butter tea with yak butter.

Beyond dietary use, tea bricks had medicinal applications. In traditional Chinese medicine, pressed tea was believed to aid digestion, reduce fever, and improve blood flow. Ancient bricks, especially aged puer, are highly prized by collectors and can fetch high prices at auctions. Today, artisanal production continues, with techniques that have remained virtually unchanged for centuries.

Frequently Asked Questions

Why were tea bricks used as currency?

They were easy to transport, standardized in weight and value, and resistant to spoilage during long journeys. In Central Asia, where tea was scarce, bricks became a reliable medium of exchange.

What is the difference between tea bricks and loose tea?

The brick is compressed and compacted, which extends its shelf life and makes storage easier. Additionally, the flavor matures differently due to slow oxidation during aging.

How do you prepare tea from a brick?

Scrape or cut a small portion (about 5 grams), place in hot water (90-95°C), and steep for 1-3 minutes. It can be re-infused several times.
