Reading these posts with greedy and absorbed fascination.
Unfortunately, I have never seen (let alone tasted) a coffee from Hawaii, and have neither seen nor sampled Kona or Kuauai coffee beans. For that matter, I've never seen Kona blends for sale here in my corner of Europe, but, in truth, I rarely buy blends, preferring single origin coffee.
Around a decade ago, I sometimes used to order coffees from the US, and used a few highly regarded companies - Intelligentsia, I recall, in particular; they had some really interesting and unusual coffees, and I was introduced to coffees that I would never have encountered (or sampled) otherwise - such as some of the excellent coffees they stocked from El Salvador.
However, customs & excise charges (frequently equalling, if not exceeding, the actual cost of the coffee) put an end to that adventure.
