7542: The Benchmark Raw Tea Recipe

When it comes to raw pu'er, 7542 is probably the tea most often used as a yardstick. It isn't a tea from one particular year but a recipe made continuously from 1975 to today. For many tea drinkers, the first raw tea they compare others against is a cake of 7542.

What the Four Digits Mean

Following the usual reading of Menghai Tea Factory recipe codes, 7542 breaks into three parts:

The Dayi Group's published chronology also says that in 1975 it produced the 7542 raw cake and 7572 ripe cake, which became industry benchmarks. So "75" matches the year and "2" matches the factory. The full coding rules are in How Recipe Codes Work, and the overall picture of classic recipe codes is in 7542, 8582, 7572: The Stories Behind Pu'er's Classic Recipes.

One thing to remember: 7542 is a recipe code, not a production year. A 7542 made in the 2020s and one made in the 1980s share the same code; for the actual year, check the production date or batch number on the package.

Why It's Called a Benchmark

It's the archetypal blend. 7542 uses mid-grade grade 4 material as its backbone, blended with material of other grades and regions, and the surface of the cake is often sprinkled with more tender buds and leaves, a technique called "sa mian." This keeps the style of each year's tea stable and the taste balanced. Zou Bingliang, the former Menghai Tea Factory director who helped set the recipe, said in an interview that 7542 was the first blended recipe. For the principles of blending, read Blending: The Art of the Recipe.

It's been made for a long time, in large amounts. Menghai Tea Factory had only a few qizi bing products in the 1970s, and 7542 was one of them. It has been produced almost every year since, leaving samples spanning decades. Dayi groups it with 7572, 8582, 8592, and 7262 as the "five classic recipes."

It's the control group for collecting and research. A Hong Kong auction catalog describing 1980s thick-paper 7542 said it is regarded in the pu'er world as the standard product for judging raw tea quality. A research team has also analyzed 7542 from different years and observed that tea polyphenols, catechins, and amino acids decreased with age while flavonoids increased, with more noticeable turning points around year 3 and year 8.

Is Young 7542 Good to Drink?

Fresh from the factory, 7542 has a direct personality: the liquor is yellow-green to golden, the aroma bright and lifted, with clear bitterness and astringency on the palate and a quick huigan. People who like liveliness and punch find it satisfying; those used to a smooth mouthfeel may find it too aggressive.

To make young 7542 more comfortable to drink, adjust like this:

• Use a little less leaf: 5–6 grams in a gaiwan of about 110 ml.
• Slightly cooler water: start at 90–95°C and go hotter if it's too weak.
• Pour off quickly: 5–10 seconds for the first few infusions.

How 7542 Differs by Year

The same recipe can taste very different from year to year, for three main reasons:

1. Material and processing change: tea gardens, sources, and pressing methods have changed over the decades, and 7542 from different eras shows visible differences in leaf shape and compression.
2. Storage time: young tea shows clear floral and fresh notes; after 5–10 years, bitterness and astringency soften and honey and aged notes appear; older 7542 is often described as having camphor and woody notes, with an orange-red liquor.
3. Storage environment: 7542 from the same year changes at different rates in Kunming, Hong Kong, or Taiwan. Dry storage keeps more of the tea's own layers, while humid storage changes it faster and darkens the liquor. Read Dry and Wet Storage and Regional Storage.

The tea world has also cautioned that before 2005, the 7542 number was loosely controlled, and there are custom teas on the market printed with 7542 that weren't made by Menghai Tea Factory. When you come across an older 7542, confirm which factory made it first rather than going by the number alone.

What Is 88 Qing?

"88 Qing" is collectors' nickname for a group of 7542 raw cakes, not an official factory product name. The common definition is 7542 made by Menghai Tea Factory around 1989–1992 and aged naturally in dry storage.

Accounts of the name differ. One says "88" refers to 1988; another traces it to Hong Kong tea figure Chan Kwok-yee, who later said the tea was bought from 1992 onward and that "8" was chosen because it sounds like "prosper" in Cantonese, with no connection to 1988. Around 2013, he publicly defined the range as 7542 made by Menghai Tea Factory from 1988 to 1992 that meets dry-storage conditions. The full story is in Named Teas in Collecting Circles.

Getting to Know 7542

• Start with a recent 7542, and note the strength of its bitterness and astringency and the direction of its aroma.
• Then find one aged 5 years or more, brew it the same way, and compare to feel the changes that aging brings.
• Finally, compare it with a single-mountain tea, and you'll be able to tell "the balance of a blend" from "the personality of a single region."

There's no need to hunt for which one is best. Finding the year and storage style you like is the most interesting thing about 7542.
