Jose Kawashima travels around the world visiting coffee producing countries, and from time to time he comes across with rare coffee species and coffee growers who are working hard to improve quality by introducing their own cultivating and processing methods. Jose has long wanted to convey to Japanese coffee enthusiasts the thought of such coffee growers.
Such growers were not aware of the coffee needs in the consuming countries, and concurrently there were not buyers in the consuming countries who were interested in bringing the coffee produced by such growers.
Jose then embarked upon a project called Coffee Hunters in which the coffees of such producers on the worldwide scale would be Introduced to the consuming countries.
While Grand Cru Cafe is packaged in pressurized Champagne bottles. Coffee Hunters is packaged in pressurized PET bottles.
At the very beginning of the Grand Cru Cafe project, a PET bottle was first tested but it became bulged and it was a failure. Then, a PET bottle for carbonated beverages was tested and it was a success by preserving quality. Jose was, however, reluctant to use PET bottles for Grand Cru Cafe.
In the Coffee Hunter project with a different concept from Gran Cru Cafe, Jose intended to bring his coffee to a greater number of consumers at a lower cost. Despite the cost reduction efforts in mind, pressurized package was the only approach even for Coffee Hunters, and a pressurized PET bottle was a solution.
In the case of PET bottles for roasted beans, nitrogen gas is charged into the bottle
and this keeps oxygen at the level of less than 1%. In the case of ground coffee, instead of using nitrogen gas whose charging creates coffee dust, not a practical way, a specialized oxygen scavenger is in use so as to generate a certain amount of carbon dioxide which counter-balances the amount of oxygen absorbed.
When a PET bottle is opened, coffee aroma spreads with a whishing sound like a carbonated beverage bottle.
