What Do Brazilian, Colombian, and Blue Mountain Coffee Beans Look Like?

If you’ve ever tried to identify different green coffee beans by sight—whether you’re a roaster, importer, or curious home enthusiast—you’ve likely wondered how Brazilian beans differ from those from Colombia or Ethiopia. The truth is, green coffee beans carry visible traits tied to their origin, processing, and variety. But without a guide, it’s hard to know what you’re looking at.

Here’s a clear reference: we’ve gathered visual examples of key specialty-origin green coffee beans, including Brazil, Colombia, Jamaica Blue Mountain, Indonesia Mandheling, Vietnam, and Java. Each image shows the typical shape, size, density, and color you can expect from beans grown in these regions—details critical for roasters and buyers alike.

Brazilian Coffee Beans

Brazil is the world’s largest producer of coffee, known for its vast plantations and high-volume output. Brazilian green coffee beans are typically small to medium in size, with a flat, oval shape and a range of pale to medium greens. Common processing methods include natural (dry) and pulped natural, leading to a range of sweetness and body. These beans are widely used in espresso blends for their low acidity and chocolatey, nutty profiles.

Colombian Coffee Beans

Colombia is famed for its high-altitude arabica production, particularly varieties like Caturra and Castillo. Colombian green beans are medium-sized, often rounded with a slight oval shape, and typically display a vibrant, uniform medium green. The country’s emphasis on washed processing contributes to clean, bright cups with notes of citrus and caramel. Colombian beans are a staple in single-origin offerings and balanced blends.

Jamaica Blue Mountain Coffee Beans

Jamaica Blue Mountain beans are among the most prestigious and tightly regulated coffees in the world. These beans are medium to large, with a very consistent size and a bluish-green hue. Grown at elevations between 1,200 and 1,700 meters, they are carefully cultivated, handpicked, and processed to strict standards. The beans are known for their mild flavor, lack of bitterness, and smooth body—often sought after for specialty filter coffee.

Indonesian Mandheling Coffee Beans

Indonesia, particularly Sumatra, produces some of the most unique green beans in the world. Mandheling beans—though the name is a trade term—are typically large, irregular in shape, and have a distinct blue-green to greyish color. These beans are often processed using the wet-hull (giling basah) method, which contributes to their full body and earthy, spicy flavors. They are a key component in many dark roasts and espresso blends.

Vietnamese Coffee Beans

Vietnam is the world’s second-largest coffee producer, overwhelmingly focused on robusta. Vietnamese green robusta beans are smaller, rounder, and have a darker, more olive-toned green compared to arabica. They are highly caffeinated, with a strong, bitter profile suited for traditional Vietnamese iced coffee and espresso blends. Most are processed using the dry method.

Java Coffee Beans

Java, part of Indonesia’s island chain, has a long history in coffee cultivation. Java green beans are typically medium in size with a more standard arabica shape, and a medium to light green color. The island’s beans are often associated with classic colonial-era coffee profiles and are still used today in both single-origin and blended coffees. Processing varies, but washed methods are common.
