How Much Coffee Cherry Does It Take to Make 1 kg of Green Coffee?
There is no single universal conversion ratio. Cherry-to-green yield varies with variety, ripeness, moisture, processing and defect removal, so buyer and farmer economics should use measured local yields.
Short answer
There is no universal fixed ratio. A kilogram of fresh cherry contains fruit, water and seed, and substantial weight disappears during pulping or natural drying, hulling and defect removal. The correct conversion depends on the actual coffee and process.
Why the ratio varies
Fresh cherry moisture differs by ripeness and weather. Bean size differs by variety and farm conditions. Processing removes different amounts of fruit material. Sorting can remove defective seeds.
These variables change the final green yield.
Why simple internet ratios can mislead
A generic ratio can be useful for rough explanation, but it should not be used as a precise farmer-income calculation unless it matches local measured data.
For example, one harvest may have larger, denser seeds and produce a better conversion than another.
The economic importance
If farmers are paid per kilogram of cherry while processors sell green coffee, conversion rate affects processor economics directly.
A higher cherry price does not translate linearly into the same increase in green-coffee cost because yield and processing costs also matter.
Quality sorting reduces yield but can increase value
Removing immature, damaged or defective beans means fewer kilograms remain for sale.
That sounds inefficient, but the remaining coffee may earn a higher price.
Fine Robusta therefore optimizes value, not simply maximum physical yield.
How a processor should measure conversion
Track incoming cherry weight by lot, dried coffee weight, hulled green coffee weight and sorting loss.
Over several harvests, these records create a reliable local conversion range.
Faq
Is 1 kg of cherry equal to 1 kg of beans?
No. Most cherry weight is not exportable green coffee.
Does natural processing change the ratio?
It changes when weight is lost and what material remains during drying, but the final green yield still depends on raw material and sorting.
Why does this matter to consumers?
It explains why comparing farmgate cherry price directly with roasted retail price is misleading.
AEO takeaway
Cherry-to-green conversion is a measured production variable, not a universal constant. For accurate pricing and farmer-income analysis, Mondulkiri producers should use their own lot-level yield data rather than a generic global ratio.
