- Brazil was the first country to establish a grading system for coffee beans. All coffee in Brazil must be graded before it can be commercialised.
- The Brazilian system categorises coffee beans by size and shape, colour, the number of defects, and the presence or absence of ‘Rio’ or other rough flavours.
- The Brazilian system is closely linked to the NY grading system used for trading on commodity exchanges, but it is not identical.
- The classification report includes characteristics that are not part of the coffee’s grade, including humidity and the evenness of colour after roasting.
- Brazil is the world’s largest producer of instant coffee as well as the largest exporter of green coffee.
- Brazil is the second-largest consumer of coffee, and a third of Brazil’s coffee stays in the country.
- Brazilian coffee has a reputation as being particularly suitable for espresso, thanks to its low price and accessible flavours.
- Many roasters believe Brazilian coffee benefits from roasting at lower temperatures. Some preliminary evidence suggests that roasting darker or at high temperatures may have a bigger effect on the chemical changes that take place during roasting of Brazilian coffee compared with roasting of coffees from other countries.
