Goroka is coffee
Goroka is the leading centre in PNG’s small coffee industry, with hundreds of small growers in the Eastern Highlands and a many mills. here, in a coffee warehouse, samples of coffee from a batch that has been milled are ‘cupped’ or graded to determine its flavour characteristics and quality, prior to despatch for export. Cupping involves slurping samples from cups, several samples are taken from each batch.
You can read about PNG coffee at the Coffee Industry Corporation’s website, http://www.coffeecorp.org.pg/Coffee%20in%20PNG.html. The picture on their page shows women holding coffee fruit, called ‘cherry’, each of which contains two beans. Coffee processing is a fairly straightforward process, basically you extract the beans from the fruit (on the left), husk it and roast it (on the right). Tasol!
