Grade 3 green coffee beans are the quiet workhorse of high-volume coffee menus. If you run a roastery or a commercial coffee company supplying cafes, you already know the math: when a drink is built on milk, syrup, and ice, paying a specialty premium for the green bean rarely shows up in the cup. This guide covers what Grade 3 means under Indonesian grading, why it lowers your cost per kilo without wrecking flavor, how it holds up in espresso and americano, and how to choose between Grade 3 Arabica, Grade 3 Robusta, or a blend you spec yourself.

What Are Grade 3 Green Coffee Beans?
Grade 3 green coffee beans are commercial-grade lots classified under Indonesia’s national standard, SNI 01-2907-2008, published by Indonesia’s National Standardization Agency (BSN). The standard sorts green coffee by defect value, counted from a 300-gram sample, where black beans, broken beans, husk, and foreign matter each add points. The lower the defect value, the higher the grade.
Here is where Grade 3 sits:
| Grade | Defect value (per 300g) | Typical use |
|---|---|---|
| Grade 1 | Maximum 11 | Specialty and single-origin lots |
| Grade 2 | 12 to 25 | Premium commercial |
| Grade 3 | 26 to 44 | Commercial: milk-based drinks and blends |
| Grade 4 to 6 | 45 to 225 | Industrial and instant coffee |
Moisture content is capped at 12.5% across every grade, so a Grade 3 lot is still export-clean and properly dried. What pushes a lot out of specialty and into Grade 3 is the higher defect count, not spoilage. A Grade 1 lot needs a defect value of 11 or less and a cup score above 80 points to qualify as specialty. Grade 3 carries more visible imperfections, which is exactly why it costs less while staying perfectly usable for commercial coffee programs.
Why Grade 3 Cuts Cost Without Killing the Cup
The cost gap is the whole point. ISC’s Grade 3 Arabica runs about $6.85 per kg in bulk, against $8.50 per kg and up for a Grade 1 Arabica like Aceh Gayo. Grade 3 Robusta drops to about $3.90 per kg. For a cafe pushing out hundreds of milk drinks a day, or a roaster filling a house-blend contract, that difference compounds into real margin across every container.
Now the cup reality. Milk, syrup, sugar, and ice flatten the delicate florals and bright acidity you pay a premium for in a Grade 1 lot. A caramel latte does not reward an 87-point washed single origin. It rewards body, sweetness, and a roast that cuts through dairy. Grade 3 delivers that profile for a fraction of the green cost, which is why so many commercial buyers reserve their specialty lots for black coffee and pour-over menus, and run Grade 3 for everything built on milk.

Grade 3 for Espresso and Americano
Grade 3 green coffee beans still pull a solid espresso and a clean Americano, particularly with Indonesian beans. Indonesian Grade 3, whether semi-washed, wet-hulled (Giling Basah) Arabica or natural process, dry-hulled Robusta, carries the heavy body, low acidity, and dark chocolate or earthy notes that hold their shape under nine bars of pressure and through the hot water of an americano.
Roast a touch darker to even out the less uniform bean, and you get a forgiving, repeatable shot. One thing we tell buyers from handling these lots every day: Grade 3 has a wider spread of bean size and density than Grade 1, so the smalls can scorch before the larger beans develop. A slightly longer, more even roast solves it. Brief your roast team to develop the batch rather than chase a fast finish, and the cup quality climbs noticeably.
Grade 3 Arabica, Robusta, or a Custom Blend?
You have three ways to buy Grade 3, and the right one depends on your menu and your target cost.
| Option | Bulk cost | Cup character | Best for |
|---|---|---|---|
| Grade 3 Arabica | ~$6.85/kg | Smoother, more aroma, chocolate, and earthy | Americano, black filter, softer milk-drink base |
| Grade 3 Robusta | ~$3.90/kg | Bold, bitter, heavy crema, high caffeine | Espresso base, milk drinks, lowest cost |
| Custom blend | Between the two | Tuned to your spec | Signature house espresso |
You can run Grade 3 Arabica alone, Grade 3 Robusta alone, or blend them at any ratio you specify. A common commercial move is a Robusta-forward blend, say 70/30 or 50/50 Robusta to Arabica, for thick crema and a caffeine kick in milk drinks, with enough Arabica to round off the bitterness. Indonesian Lampung Robusta is the usual Robusta base, and it blends cleanly with a Sumatran Grade 3 Arabica. ISC blends to your ratio before shipping, so you receive a single, consistent green lot rather than two bags to mix yourself.
What Grade 3 Looks Like vs How It Tastes
Be ready for this: Grade 3 green looks rougher than Grade 1. You will see more color variation, the occasional broken or black bean, and less uniform sizing. Set next to a clean Grade 1 lot, it is not pretty.
Appearance and cup quality are not the same thing, though. Once the coffee is roasted and pulled into an espresso or built into a latte, the visual imperfections of the green bean disappear, and what stays in the cup is body and flavor. For Indonesian Grade 3, that flavor stays genuinely good, because the earthy, full-bodied, low-acid character of Sumatran and Lampung coffee does not depend on a flawless bean. Buyers who fixate on green aesthetics often overpay for a quality their own customers never taste.

Frequently Asked Questions
What is a Grade 3 green coffee bean?
A Grade 3 green coffee bean is a commercial-grade lot with a defect value of 26 to 44 per 300-gram sample under Indonesia’s SNI 01-2907-2008 standard. It has more visible defects than specialty Grade 1, but stays export-clean at a maximum 12.5% moisture.
Is Grade 3 coffee still good for espresso?
Yes. Grade 3 beans pull a solid espresso and americano, especially Indonesian lots with heavy body, low acidity, and dark chocolate notes. Roast slightly darker and develop the batch evenly to balance the wider bean size, and the shot holds up well in milk drinks.
How much do Grade 3 green coffee beans cost?
ISC’s Grade 3 Arabica is about $6.85 per kg and Grade 3 Robusta about $3.90 per kg in bulk, FOB Belawan, for orders of 9 tons and up. For quantities below one container, ISC issues a custom quotation based on volume and blend.
Can I blend Grade 3 Arabica and Robusta?
Yes. You can order Grade 3 Arabica alone, Robusta alone, or a blend at any ratio you specify, such as 70/30 or 50/50. ISC blends to your spec before shipping, so you receive one consistent green lot that is ready to roast on arrival.
What is the difference between Grade 1 and Grade 3 coffee?
Grade 1 has a defect value of 11 or less and can reach specialty cup scores above 80 points. Grade 3 has a defect value of 26 to 44 and is a commercial grade. The practical trade-off is cup refinement versus cost per kilo.
