How it sits among coffee from Indonesia

How often roasters use each flavour family to describe coffee from Indonesia: 142 of 189 carry notes. The dashed outline is the whole catalogue. These are the roasters’ own words, grouped — not our tasting, and not a measurement.

St Martins Coffee Roasters describe this coffee as fruity, caramel and sweet, chocolate. The filled shape is how often roasters use each family across coffee from Indonesia; the rings on the rim are this coffee’s own.

Every family the roaster names is a common one for coffee from Indonesia, so this reads as a typical example rather than an outlier.

What the roaster says about where it came from

Country
Indonesia, Nicaragua
Not stated
region, farm or estate, producer, process, variety, altitude, harvest, lot, importer, price paid to the producer

We report what the roaster publishes and we have not checked any of it independently. A fact nobody publishes is not a fault of the coffee: almost no roaster in the UK states an importer or the price paid to the producer.

Taken from the roaster’s own pages, and nothing here has been verified by us or by an independent body. What we store is a passage of page text cut around the fact, so one shown with an ellipsis is a passage we cannot see the start or the end of; only the fully quoted ones are complete sentences.
