How Did Coffee Names Like Blue Mountain and Mocha Originate?
Ever wondered why your cup of coffee is called "Blue Mountain" or "Brazil"—or what makes one coffee "special grade" and another just "ordinary"? The names and grades we see on coffee bags aren’t random. They reflect where the coffee came from, how it was grown, and how it was processed. If you’ve ever taken a closer look at your bag’s label and asked, “What does this even mean?”, you’re not alone.
The short answer: Coffee names come from export ports, mountain regions, coffee varieties, and processing methods, while grades are based on bean size, altitude, and defect counts. Over a dozen factors—from the port of shipment to the number of flawed beans—determine what ends up printed on your bag.
Port Names: Where the Coffee Was Shipped From
Many coffee names derive from the port through which they were exported. For example, “Brazil. Santos” means the coffee was shipped from the port of Santos. This usually indicates the coffee’s origin region or trade route, since beans from the same area often leave through a common port. However, “Mocha” is an exception—it originally referred to the Yemeni port of Al-Makha (Mocha), and today, some Yemeni coffees still carry the historic name. Similarly, “Harar Mocha” refers to Ethiopian beans linked to that historic trade route.
Varietal & Regional Names: Arabica, Robusta & Famous Mountains
Some labels specify the coffee species, especially when distinguishing between Arabica and Robusta. For instance, you might see “Uganda. Robusta” or “Cameroon. Arabica.” Certain well-known coffee-growing mountains also lend their names to the coffee, such as Blue Mountain (Jamaica), Kayu Mas (Indonesia), Cerro Azul (Costa Rica), Crystal Mountain (Cuba), Kilimanjaro (Tanzania), and Mount Hagen (Papua New Guinea). These names signal premium single-origin coffees tied to iconic growing regions.
How Coffee Gets Its Grade: Size, Altitude & Defects
Different countries use their own grading standards, but several criteria are widely applied:
Washed vs. Natural Process
Washed (or wet-processed) coffee is cleaned using water to remove the fruit and mucilage before drying, resulting in a more consistent flavor profile. Natural (or dry-processed) coffee is dried with the fruit still on the bean, which can lead to more variable quality.
Flat Bean vs. Peaberry
Most coffee cherries contain two flat-sided beans. Occasionally, a cherry produces a single round bean called a peaberry. Peaberries are not necessarily tastier, but they are sorted separately. All coffee beans start as green seeds inside red or yellow coffee cherries; the flat beans are the norm, while peaberries are the exception.

Bean Size (By Screen Size)
Many countries, including Brazil, Colombia, and Tanzania, classify beans by mesh size (screen number), which helps ensure uniformity. Though size doesn’t always correlate with quality, uniform beans roast more evenly. Here’s how screen numbers typically correspond to bean size:
| Bean Type | Screen Number | Size |
|---|---|---|
| Flat Bean | 20–29 | Extra Large |
| Flat Bean | 18 | Large |
| Flat Bean | 17 | Medium-Large |
| Flat Bean | 16 | Standard |
| Flat Bean | 15 | Medium |
| Flat Bean | 14 | Small |
| Flat Bean | 13–12 | Extra Small |
| Peaberry | 13–12 | Large |
| Peaberry | 11 | Medium-Large |
| Peaberry | 10 | Standard |
| Peaberry | 9 | Medium |
| Peaberry | 8 | Small |
Altitude-Based Grades
Coffee is also graded by the elevation at which it’s grown. Higher altitudes generally produce denser, higher-quality beans. Common grade classifications include:
| # | Grade | Abbreviation | Elevation (meters) |
|---|---|---|---|
| 1 | Strictly Hard Bean (SHB) | S.H.B | 4,500+ |
| 2 | High Grown Bean | H.B | 4,000–4,500 |
| 3 | Medium Bean | S.H | 3,500–4,000 |
| 4 | Extra Fine Washed | E.P.W | 3,000–3,500 |
| 5 | Fine Washed | P.W | 2,500–3,000 |
| 6 | Extra Good Washed | E.G.W | 2,000–2,500 |
| 7 | Good Washed | G.W | up to 2,000 |
Quality via Defect Count
Beans are assessed for defects—such as insect damage, underripe beans, black beans, sour beans, shells, or broken beans. The fewer the defects in a sample, the higher the coffee’s graded quality. This is measured by calculating the percentage of defective beans in a given sample.
Flavor & Sensory Evaluation
Countries like Brazil, Haiti, Kenya, and Uganda conduct their own flavor tests before export. Visual inspection also matters: look for beans that are vibrant (light green without spots), uniform in shape, and free from odors like mold, fermentation, or earthiness. Experienced graders can spot issues quickly, but even novices can learn to identify off smells or flawed beans over time.
Frequently Asked Questions

Why do some coffees have port names like Santos or Mocha?
These names refer to the historical or current export ports where the coffee was shipped. For example, “Santos” indicates coffee exported from Brazil’s Santos port, while “Mocha” originally came from Yemen’s Al-Makha port and is now used for certain Yemeni or Ethiopian coffees linked to that trade history.
What’s the difference between flat beans and peaberries?
Most coffee cherries contain two flat-sided beans (flat beans). Rarely, a cherry produces a single round bean called a peaberry. They taste similar but are sorted separately, and peaberries sometimes roast differently due to their shape.
How does altitude affect coffee grading?
Higher-grown coffee (above 3,000 meters) is typically denser and considered higher quality. Grades like SHB (Strictly Hard Bean) are given to beans grown at 4,500 meters or above, while lower-altitude beans get grades like G.W (Good Washed) for those grown below 2,000 meters.
What do defect counts mean in coffee grading?
Defects include broken, insect-damaged, sour, or unripe beans. The fewer defective beans found in a sample, the higher the grade. Graders calculate the percentage of defects to determine overall coffee quality.
Do coffee names always reflect where the beans were grown?
Often, but not always. Some names refer to ports of export (like Mocha), processing methods, or historical trade routes. However, many famous names—like Blue Mountain or Kilimanjaro—are tied directly to the growing region.
