The negative differential for PNG arabica is mainly due
to higher than average transport costs for this origin.
Whilst PNG Y-1 grade meets the quality specifications of the New
York C Contract (futures market) and is deliverable at par, the
coffee often shows a certain wineyness in the cup. New York graders
who taste all coffee to be certified against the C Contract often
consider pronounced wineyness as a defect and as a result
many lots are rejected. Consequently few lots are actually
submitted for certification against the C Contract, mostly because
a rejection usually means a substantial drop in value. *
Experienced tasters and blenders know how to use this type of
coffee and at times may even search it out to achieve certain taste
combinations. However, high transport costs from Papua New Guinea
alone can mean large discounts, as much as 5 to 7 cts/lb plus a
quality differential where applicable. Differentials
constantly fluctuate of course. **
* Winey: A fruity taste similar to fresh wine. Not necessarily
unpleasant when the taste is in the background. The acceptability
of 'wineyness' is a subjective judgement but certainly a light
fruity wineyness is a postive taste attribute. See chapter 11
Coffee Quality for more on this.
** The differential between the New York C Contract price and
the FOB value of a coffee reflects many aspects, including quality
and of course transport costs if these are substantially higher
than for comparable origins.
