Yunnan Small Coffee Bean Harvest & Processing Standards

When you sip a cup of specialty coffee from Yunnan, you’re tasting the result of careful choices made long before roasting—starting in the orchard, where every red coffee cherry must be picked at just the right moment. But what defines that ‘right moment’? How are these tiny Arabica cherries sorted, packed, and kept fresh before processing? This guide breaks down the exact standards used for Yunnan’s small coffee beans, from harvest to storage.

The key numbers? Harvest runs from October to March; only bright red, intact cherries count as Grade 1; and all picked fruit must be processed or stored (in water or cool, dark conditions) for no more than two days.

What Is a Small Coffee Cherry?

In specialty coffee terms, ‘small coffee beans’ often refers to the fruit of the Arabica variety—specifically, the small, dense berries produced by cultivars like Typica. In Yunnan, these are called ‘small-seed coffee’ , a local name for Arabica, whose cherries are notably smaller than those of other species. A coffee cherry is the whole fruit: a thin skin (exocarp), juicy pulp (mesocarp), sticky mucilage, parchment layer, and finally, the two seeds (beans) inside. When we talk about ‘fresh coffee fruit,’ we mean the entire ripe cherry, picked directly from the tree.

When and How to Pick Yunnan Coffee Cherries

The harvest window for Yunnan’s small Arabica cherries spans five months: from October through March. Not all cherries ripen at once, so pickers must work in passes. The critical sign of ripeness? Bright red color. Only fully red, mature cherries should be harvested—green or purple (overripe) fruits are left for later rounds. Pickers work from the inside of the tree outward, plucking single cherries by hand to avoid damaging branches or leaving stems (which can hurt future yields). Grading begins at harvest: only red, unblemished, intact cherries make the cut for top-quality lots.

Coffee Cherry Grades: What Determines Quality?

Yunnan’s small coffee cherries are sorted into three grades based on ripeness and appearance:

• Grade 1: Fully red, normal-mature cherries with no scars or damage.
• Grade 2: Red cherries with minor stem-end greenness, slight overripeness (purple tint), or localized scars; also includes slightly underripe fruit.
• Grade 3: All other cherries not meeting Grade 1 or 2 criteria.

Pickers follow strict rules: only red cherries are taken in early passes, and every batch is separated by grade. Even in the final pass, when both red and green cherries are collected, the separation remains critical for processing quality.

Packaging, Transport, and Temporary Storage Rules

Once picked, coffee cherries must be packed immediately. Each bag holds cherries from the same variety, grade, and harvest day only. Packaging must be sturdy, clean, non-toxic, odor-free, and undamaged. Labels must clearly show: product name, grade, standard number (DB53/T 154.3—2006), net weight, producer name, origin, and production date. For transport, cherries move by hand or vehicle—but the truck bed (or container) must be clean, non-toxic, and free of odors. Most importantly, cherries shouldn’t sit overnight. If temporary storage is unavoidable, they can be held in water or on clean, ventilated, dark flooring—but never for more than two days.

Frequently Asked Questions

When is the coffee cherry harvest season in Yunnan?

The official harvest period for Yunnan’s small coffee cherries runs from October to March each year. Pickers collect fruit in multiple passes during this window, selecting only fully ripe cherries each time.

What counts as a Grade 1 coffee cherry in Yunnan?

Grade 1 cherries are fully red, normally mature, and completely free of scars, blemishes, or damage. These top-grade fruits are picked first and processed separately for higher-quality lots.

How should coffee cherries be picked to protect future yields?

Pickers must harvest by hand, working from the tree’s interior outward, and pluck only individual red cherries—never pulling stems or damaging branches. Leaving stems or breaking twigs can reduce next year’s crop yield.

What is the maximum storage time for freshly picked coffee cherries?

Freshly picked cherries should ideally be processed the same day. If temporary storage is needed, they can be kept in water or on clean, ventilated, dark flooring for no more than two days—regardless of grade.

How are coffee cherries graded in Yunnan?

Cherries are sorted into three grades: Grade 1 (fully red, unblemished), Grade 2 (red with minor flaws or slight overripeness), and Grade 3 (all other cherries). Grading starts at harvest and determines how cherries are processed and packaged.
