What Is Yunnan Catimor? AA Grade Coffee Bean Images

If you've ever searched for 'Yunnan coffee bean pictures' or wondered what a high-grade Catimor coffee bean looks like up close, you're not alone. Many coffee enthusiasts, roasters, and importers want a clear visual reference for the beans they’re sourcing from China—especially those labeled 'AA grade' or 'small-bean Yunnan'. This article shows exactly what one of Yunnan’s most widely planted varieties looks like in its green, raw form.

The answer is straightforward: AA-grade Yunnan Catimor beans are notably small, very uniform in shape, and visually typical of what the region calls 'small-bean' coffee. These images show beans from Ning’er County’s Dahei Mountain area—part of Yunnan’s well-known Pu’er tea region.

What Is Yunnan Catimor?

Catimor is a hybrid coffee variety, a cross between Caturra and Timor Hybrid (itself a Robusta-Arabica cross). It was developed for disease resistance, especially to coffee leaf rust, and is widely grown across Asia and Latin America. In Yunnan, Catimor is among the most commonly cultivated coffee varieties due to its hardiness and relatively high yields. Though not typically known for complex cup profiles, well-grown Catimor can still deliver balanced, approachable flavors when processed carefully.

Why Are These Yunnan Catimor Beans Considered AA Grade?

In the Chinese coffee grading system, ‘AA’ refers to the largest and highest-quality beans in a lot—but Catimor beans are naturally smaller than other Arabica types like Typica or Bourbon. So in Yunnan, ‘AA grade’ Catimor refers more to bean uniformity, density, and absence of defects rather than absolute size. These particular beans are classified as AA due to their consistent size and clean appearance, despite being physically small compared to other global Arabica standards.

Where in Yunnan Are These Catimor Beans Grown?

The beans pictured were grown in Ning’er County’s Dahei Mountain , located in Pu’er City, Yunnan Province. This area is part of the same region famed for Pu’er tea production. The mountainous terrain, elevation, and climate create conditions suitable for coffee cultivation, and Dahei Mountain has become known for producing quality small-lot coffee alongside its tea heritage.

What Do AA-Grade Yunnan Catimor Green Beans Look Like?

In the provided images, you can see that these Yunnan Catimor beans are:

• Very small in size compared to other Arabica beans
• Uniform in shape and color
• Free from obvious defects or discoloration
• Typical of what Yunnan growers refer to as 'small-bean' coffee

These traits are consistent with the visual profile of high-quality Catimor grown in the region. The beans are dense and dry, as expected for green coffee ready for export or roasting.

The small size is a defining feature of Yunnan’s 'small-bean' coffee classification, which often includes Catimor and some other hybrid varieties. Despite their compact size, these beans are well-formed and suitable for both commercial and specialty-grade roasting, depending on processing and farm management practices.

Are Yunnan Catimor Beans Worth Roasting?

Yes. While Catimor is often dismissed for having less desirable cup qualities compared to traditional Bourbon or Typica varieties, properly grown and processed Yunnan Catimor can produce balanced, mild cups with notes of nuts, chocolate, and mild acidity. When roasted with care, especially in lighter to medium profiles, these beans can shine in espresso blends or as single-origin offerings. Many roasters use Yunnan Catimor in commercial or entry-level blends due to its consistency and cup balance.
