6 Tips How to Ensure You Are Getting 100% Arabica Beans in Your Delivery

Australian coffee culture is built on a foundation of quality. We take our morning brew seriously, whether it’s a flat white at a local café or a pour-over in our own kitchens. However, navigating the coffee market can be tricky. While many bags claim "premium" status, not all are created equal. The most common discrepancy usually lies in the bean species itself: Arabica versus Robusta.

Arabica beans are prized for their complex sugar strains, lipids, and acidity, which create the fruit, berry, chocolate, and nut flavours we love. Robusta, often used as a cheaper filler to bulk up blends, is rubbery, bitter, and significantly lower in quality.

To ensure you are truly getting the 100% freshly roasted Arabica coffee beans you are paying for, you need to look beyond the marketing slogans. Here is a comprehensive guide to verifying the quality of your coffee delivery.

1. Scrutinise the Packaging for Explicit Guarantees

The first step happens before you even open the bag. In Australia, food labelling is generally strict, but there is still room for ambiguity. A bag labelled "Barista Blend," "Premium Roast," or "Espresso Style" does not guarantee Arabica. These terms often mask the inclusion of Robusta, which is used to increase caffeine content and create a thick, albeit bitter, crema.

You must look for the specific phrase "100% Arabica" on the packaging. If a roaster is using pure Arabica, they will want to brag about it. Furthermore, look for "Specialty Grade" markings or a cupping score (SCA score). Specialty coffee is defined as Arabica scoring 80 points or higher on a 100-point scale. If these details are missing, it is safer to assume the blend has been compromised.

2. Analyse the Geography and Altitude

High-quality Arabica is notoriously difficult to grow. It requires specific climates and high elevations, typically between 600 and 2,000+ metres above sea level (MASL). Robusta is a hardy plant that grows easily at low altitudes.

Check the label for altitude information. If a roaster lists the specific elevation (e.g., "Grown at 1,500 MASL"), it is a strong indicator of Arabica. Additionally, "Single Origin" coffees are almost exclusively Arabica. While 100% Arabica blends exist, buying Single Origin is one of the safest ways to ensure purity, as Robusta is rarely sold on its own in the specialty market.

3. Perform the Visual "Shape and Crease" Inspection

Once you have the beans in hand, the physical characteristics are the most telling evidence. Pour a handful onto a flat, white surface and inspect them closely.

The Shape: Arabica beans are generally oval, slightly larger, and flatter. In contrast, Robusta beans are smaller, rounder, and thicker, resembling a pea. If you see a mix of ovals and small round beans, you are likely looking at a blend mixed with filler.

The Crease: Look at the line running down the centre of the bean. On an Arabica bean, this line is usually curved, resembling an "S" shape or a wavy line. On a Robusta bean, the crease is typically straight. This is one of the most reliable visual tests a consumer can perform.

4. Assess the Aromatics

Your nose is a powerful tool for detecting quality. Grind a small amount of coffee and smell it immediately. Arabica beans contain distinct lipids and sugars that release complex aromas ranging from florals and berries to caramel and nuts.

Conversely, Robusta has a much lower sugar content. Its dry aroma is often described as earthy, woody, burnt, or even smelling like burnt rubber. If the aroma is flat or offensive rather than inviting and sweet, it is a sign that lower-grade beans are present.

5. The Taste Test: Acidity vs. Bitterness

The final verification lies in the cup. Brew a black coffee without sugar to strip away any masking agents. Arabica is celebrated for its acidity, often described as brightness or liveliness, balanced by natural sweetness. You should be able to identify specific notes on the palate.

Robusta is characterised by a harsh, "medicinal" bitterness that hits the back of the tongue immediately. It lacks the nuanced acidity of Arabica. If your coffee provides a massive caffeine kick but tastes predominantly of burnt wood or harsh earth, it likely contains a percentage of Robusta.

6. Evaluate the Price and Consistency

Finally, use price as a benchmark. Arabica yields less per hectare and is more labour-intensive to farm than Robusta. Consequently, it costs more. If a deal seems too good to be true, significantly undercutting other specialty options, it is likely being subsidized by cheaper filler beans.

This is where the value of a consistent supplier becomes clear. A dedicated roaster who refuses to compromise on price by diluting their product ensures that you never have to worry about batch variability. Consistency in sourcing means consistency in the cup.
