“Grade 1” is one of the most used terms in the coffee industry but also one of the least understood. It appears on labels, cupping sheets, and import documents, yet many drinkers and even some roasters are unsure what it actually measures.
At Bean Buster Coffee, clarity matters. This guide explains:
- what Grade 1 means
- how coffee is graded at origin
- how grading differs from cupping scores
- why Grade 1 improves consistency and clarity
- why regions such as Ethiopia and Papua New Guinea produce high volumes of Grade 1
- what Grade 1 means in the Australian market
What Grade 1 Means
Grade 1 is the highest physical grade of green coffee. In many producing countries, it is also referred to as Specialty Grade within their formal classification systems.
To qualify as Grade 1, a lot must meet strict physical standards, including:
- very low levels of primary defects
- tight limits on total defects per 300 g sample
- consistent screen size
- correct moisture content
- clean, well-processed beans with no foreign material
Grade 1 coffees are sorted more carefully, often by hand, which produces clean and uniform lots that roast and extract with greater predictability. This is common in washed Ethiopian coffees such as our Ethiopian Reserve.
The Five-Grade System
Most origins use a variation of a five-tier grading scale:
Grade 1 — Specialty
Highest physical quality. Clean, uniform, and typically cups above 80.
Grade 2 — Premium
High quality with slightly more defects than Grade 1. Widely used in specialty blends.
Grade 3 — Exchange Grade
Commercial-grade coffee with moderate defect levels.
Grade 4 — Standard
Lower commercial quality with notable defects.
Grade 5 — Off Grade
High defect count. Often used for instant coffee or domestic consumption in producing countries.
Grade 1 vs Cupping Score
Grading and cupping are separate systems used for different assessments.
Grading measures physical quality, including defects, density, moisture, and uniformity.
Cupping measures sensory quality, including aroma, sweetness, clarity, acidity, body, and balance.
A Grade 1 lot may cup anywhere from 80 to the high 80s depending on region and processing. A well-selected Grade 2 can sometimes cup higher. They are independent measurements.
Why Grade 1 Matters
Lower grades allow more defects such as black beans, insect damage, broken beans, and quakers, all of which influence flavour.
Working with Grade 1 helps deliver:
- cleaner flavour profiles
- more predictable roasting
- greater consistency from lot to lot
Why Ethiopia and Papua New Guinea Produce More Grade 1
These regions export higher percentages of Grade 1 due to:
- hand-picking at farm level
- careful sorting and flotation at washing stations
- traditional processing methods
- smaller farms with more manual oversight
This contributes to the clarity seen in coffees such as our Papua New Guinea Reserve.

Does Grade 1 Always Taste Better?
Grade 1 reflects physical quality, not flavour preference. Taste depends on terroir, processing method, cupping score, and roast approach.
For example:
- A washed Ethiopian Grade 1 may be floral and bright.
- A Brazilian Grade 2 may deliver chocolate and nut characteristics suited to milk-based coffee.
This is why many blends combine different origins and grades to create balance.
What Grade 1 Means for Australian Coffee
Most Melbourne roasters use a combination of Grade 1 and Grade 2 depending on the intended flavour and structure. Both have roles in specialty roasting.
At Bean Buster Coffee, we prioritise:
- Grade 1 where suitable for the intended profile
- high cupping scores
- clean and well-processed lots
- origins that perform consistently in espresso and milk
Grade is one part of the selection process, but understanding it helps customers recognise quality more clearly.
Frequently Asked Questions
Is Grade 1 the highest physical grade?
Yes. Grade 1 has the strictest physical standards.
Does Grade 1 guarantee better flavour?
No. Flavour depends on processing, terroir, cupping score, and roast profile.
Does Bean Buster Coffee use Grade 1?
Yes. Many of our single origins and selected blend components are Grade 1. Some origins, such as Brazil, primarily export high-quality Grade 2 lots suited to chocolate-forward, balanced profiles.
Does Grade 1 cost more?
Yes. Hand sorting, cleaner processing, and stricter selection increase cost at origin.
Is Grade 1 the same as specialty coffee?
No. Grade 1 is a physical grade. Specialty coffee also requires a cupping score of 80 or higher.
