8582: The Large-Leaf Export Recipe

If 7542 is the balanced standard yardstick, 8582 is its bolder sibling. Large leaves, long strands, a thick liquor: when many longtime tea drinkers think of 1980s Menghai raw cakes, this is the first one that comes to mind.

When Is the 8582 Recipe From?

The Dayi Group's published chronology says that in 1985 it successfully developed the 8582 raw cake and the 8592 ripe cake. Reading it by the recipe code rules:

There's a slight variation in how the third digit is read: it's usually given as "mainly grade 8," though one auction catalog says "mainly grade 7–8 leaf." Either way, it shows that 8582 uses sturdier material than 7542. A Taiwanese financial publication has mentioned that 8582's predecessor was called the "large-leaf raw cake," that 8582 from the mid-1980s mostly came in thick-paper wrappers, and that early cakes were about 21 cm across, a bit larger and thicker than ordinary cakes.

The overall recipe code rules are in 7542, 8582, 7572: The Stories Behind Pu'er's Classic Recipes.

8582 and Hong Kong Tea Merchants

This is the most often told part of the 8582 story, and the one with the most versions.

• One account: in the 1980s, Hong Kong's Nam Tin Trading Company commissioned 8582 from Menghai Tea Factory, with then-director Zou Bingliang overseeing it, so 8582 was an export recipe made for the Hong Kong market from the start. Taiwanese newspaper reports have followed this account.
• Another account: what Nam Tin commissioned was the 8592 ripe tea, or both teas at once, and 8582 was a regular export product of Menghai Tea Factory's own.
• The official version: Dayi's chronology only says it "developed" 8582 and 8592 in 1985 and doesn't mention any commissioning client.

What's certain is that in the 1980s, Menghai Tea Factory's qizi bing were sold widely through Hong Kong, and 8582 was closely linked to the Hong Kong market and its tea merchants. Whether it came about because a particular company placed an order isn't agreed upon, so when you hear the story, take it as tea-world lore.

8582 vs. 7542

Both are blends; the difference lies in the grade and proportion of material. 7542 gives a sense of balance, "a bit of everything"; 8582, with its large leaves and plenty of stem, drinks with more weight. Neither is better. They're two different paths.

Does 8582 Suit Storage?

8582's reputation among collectors comes mainly from how it performs after storage. Common views in the tea world:

• Sturdy material with plenty of substance: it's clearly bitter and astringent when young, with lots of room to change over time.
• Plenty of stem, large leaves: the pressed cake has a bit of space inside, so it ages at a different pace from tightly pressed tea.
• A Hong Kong auction catalog describing 1980s thick-paper 8582 said that after more than 30 years of aging it was full of camphor aroma with a distinct aged character.

If you want to store it yourself, remember three things: steady temperature and humidity (relative humidity around 55%–70%), an odor-free environment, and a check once a month. For conditions in Taiwan, read Temperature and Humidity for Storing Pu'er and How to Store Pu'er at Home.

How to Brew 8582

• Young 8582: use a little less leaf than usual, about 5 grams in a 110 ml gaiwan, with 95°C water and quick pours so the bitterness and astringency don't rush out all at once.
• 8582 aged a few years: use boiling water at 100°C and steep the first few infusions 10–15 seconds. The liquor will be thicker and sweeter.
• Prying: with large-leaf, stemmy cakes, pry along the layers of leaves so they're less likely to crumble. See How to Open a Pu'er Cake.

Things to Consider When You See 8582

1. The producing factory: authentic 8582 is a Menghai Tea Factory recipe; in earlier years, teas from other sources were also printed with this number.
2. The production year: check the date or batch number on the package. Don't take 85 as the production year.
3. Storage history: 8582 from the same year stored in different places can taste like two different teas.
