Red Mark, Green Mark, Yellow Mark: The Eras and Traits of Yin-Grade Pu'er

In pu'er collecting circles, the words "Red Mark" carry about as much weight as "Songpin." Together with Green Mark, Blue Mark, and Yellow Mark, it belongs to the "Yin-grade teas," the first signature teas from the era when pu'er moved from private tea firms to state-owned tea factories. For where Yin-grade teas fit among the eras of vintage pu'er, start with Hao-Grade, Yin-Grade, and Qizi Bing.

Why Are They Called "Yin" (Mark)?

From the 1950s, Yunnan's private tea firms closed one after another, and pu'er came to be produced centrally by the state-owned system. All of it was packaged as "Zhongcha brand round tea": in the center of the cotton-paper wrapper is the Zhongcha trademark, 8 "中" characters surrounding one "茶" character. See The Origins of the Zhongcha Brand for details.

The color of that "茶" character wasn't uniform. It came in red, green (or bluish), yellow, and other colors. Wrappers were mostly printed by hand back then, so the ink color became what distinguished different batches and periods. Collectors named the teas by ink color: red is Red Mark, blue-green is Blue Mark or Green Mark, and yellow is Yellow Mark. Together they're called "Yin-grade teas" (yin meaning "print" or "mark").

Red Mark: Where Yin-Grade Tea Begins

Era: Generally believed to be the 1950s, the earliest batch of Zhongcha brand round tea. Some collectors think Red Mark production can be pushed back to the late 1940s and continued through the late 1950s; accounts don't fully agree.

Traits: Collectors' descriptions mostly mention large-leaf material from the Yiwu area, with thick leaf strands and a fairly loose cake. After decades of aging, the liquor color is deep red and the aged aroma is calm and settled. Auction catalogs mostly attribute Red Mark to the Menghai Tea Factory, but accounts of the early producing unit and material sources aren't entirely consistent.

Collectors also distinguish versions such as "Wrapperless Red Mark" (Red Mark without an outer cotton-paper wrapper) and "Red Mark Iron Cake."

Blue Mark and Green Mark: Two Names for the Same Kind

Era: 1950s–1960s.

In most collectors' usage, Blue Mark and Green Mark refer to the same kind of tea: the ink of the "茶" character falls between blue and green, so some see blue and some see green, and the names differ accordingly. Blue Mark is further divided into "Grade A Blue Mark" and "Grade B Blue Mark," with the grade stamped on the wrapper; auction catalogs often list "Grade A and B Blue Mark raw cakes."

So if you ask "are Blue Mark and Green Mark the same," the answer is that they broadly refer to the same kind of tea, though some collectors use Green Mark specifically for certain batches. When you see one, it's best to ask exactly which tea is meant.

Yellow Mark: The Tail End of Yin-Grade Tea

Era: From the 1960s on.

The "茶" character on Yellow Mark is yellow, and it's generally considered one of the later batches of Yin-grade tea. At auction you'll see "1960s Eight Zhong Yellow Mark raw cakes," as well as "Qizi Yellow Mark" produced in the 1970s by the Yunnan Branch of the China National Native Produce and Animal By-Products Import and Export Corporation. The latter belongs to the qizi bing era and is a different tea from 1960s Yellow Mark.

The End of Yin-Grade Tea

Around 1972, Yunnan's tea exports were handed to the Yunnan Tea Branch of the China National Native Produce and Animal By-Products Import and Export Corporation, "Zhongcha brand round tea" was renamed "Yunnan qizi bing," and genuine Yin-grade tea ceased production. Later teas such as the 73 raw cake (nicknamed "Little Green Mark") and Snow Mark have "Mark" in their names but are usually placed in the qizi bing era; read Collectors' Named Vintage Cakes.

What Do Yin-Grade Teas Cost Now? Public Auction Records

Yin-grade teas have no "market price." Most surviving examples are in collectors' hands and occasionally appear at auction. Take the public catalog from Hong Kong's Shihong Auction 2021 spring sale as an example (these are estimates, not hammer prices):

Actual hammer prices can vary widely depending on condition, storage, provenance, and the market that year. These figures only show the order of magnitude of Yin-grade teas at auction and don't represent the value of any particular cake.

Are the Red Marks on the Market Genuine?

Very few 1950s Red Mark cakes survive, and most have a clear collecting provenance and circulate among professional auction houses. The "Red Mark" you'll commonly see on the market generally falls into a few categories:

• Imitations: Copied wrappers and neifei (embedded tickets), with artificially aged tea passed off as old tea.
• New teas borrowing the name: In recent years some factories have released new teas named "Red Mark." The wrapper states the production year; they aren't fakes as such, but they're a different thing from the old Red Mark.
• Old teas of unclear age: Genuinely old, but not Red Mark.

A "Red Mark" priced far below auction levels and without a clear provenance is almost certainly not a 1950s tea. If you want to taste what time does to tea, starting with a new cake you like and storing it yourself is far more grounded than chasing old tea; read Pu'er Aging and Vintages.

FAQ

What is Red Mark pu'er? Red Mark is the earliest batch of 1950s Zhongcha brand round tea, named for the red "茶" character on its wrapper, and regarded as the signature Yin-grade tea.

Are Blue Mark and Green Mark the same? Most collectors mean the same kind of tea; the ink falls between blue and green, so the names differ. Blue Mark is further divided into Grade A and Grade B.

How much does a Red Mark cake cost now? Red Mark has no fixed market price. In the Hong Kong Shihong Auction 2021 spring catalog, 2 "1950s Red Mark raw cakes" were estimated at HK$1,200,000–2,000,000; actual prices vary with condition and provenance.

Are the Red Marks on the market genuine? Very few genuine 1950s pieces survive, and they mostly circulate between auction houses and collectors. A low-priced "Red Mark" of unclear provenance is most likely an imitation or a new tea borrowing the name.
