How roasters select green coffee

Several assessments sit between a sample and a contract. Knowing the sequence makes an enquiry sharper and the answer to it faster and firmer.

The use first, the lot second

Espresso, filter, milk drinks or a blend base make different demands on acidity, body and sweetness. That is why the intended use belongs at the start of an enquiry, not at the end.

Assessing the sample

A sample is roasted and tasted to a defined procedure. The SCA sets out sample preparation and tasting mechanics in standard 102, so that two houses assess the same lot comparably.

Physical assessment

Beside the cup come defects, moisture, screen size and uniformity. The SCA’s physical assessment builds on the 2004 green coffee grading system.

Volume, date, contract

Only once the profile and the physical values fit do volume, delivery date and price become concrete. We name those three deliberately late: any earlier and they would be guesses.

Sample roast and production roast

What a roast record holds

Roast date, machine, batch size, time and temperature curve, first crack, end point, colour and weight loss. Comparable sample roasts make coffees comparable with each other.

From sample to your own profile

Each roastery develops its production profile for its machine, its batch size and the intended use. A sample evaluation describes the potential of the green coffee, not the later roast profile.

In short

  • The intended use drives the selection, not the overall score.
  • SCA standard 102 governs sample preparation and tasting mechanics.
  • The SCA’s physical assessment builds on the 2004 grading system.
