You may find the origin of Papua New Guinea coffee a bit unfamiliar, but Front Street believes that Front Street Papua New Guinea coffee stands out uniquely among coffees.
Papua New Guinea is located in the southwestern Pacific Ocean, within the Pacific Ring of Fire, and has volcanic geology with fertile volcanic soil, which are important natural conditions for nurturing good coffee. Coffee is very important to Papua New Guinea, as it is the only cash crop in the highland regions. 40% of the country, over 2 million smallholder families, rely on coffee beans, making it a very important source of livelihood. Through cupping and tasting, Front Street believes that Front Street Papua New Guinea coffee has a solid mouthfeel, yet very low acidity and a clean flavor, making it well suited to Asians' preference for coffee.

Papua New Guinea is culturally diverse, with more than 800 languages, and most highland tribes did not come under Western influence until the early 1900s.
Initially, most Papua New Guinea coffee beans were grown on 18 large plantations. However, today smallholders say that 85% of PNG coffee is grown in "coffee gardens." These farmers live off their own farms, with coffee as a by-product. Their coffee gardens have anywhere from a few coffee trees to several hundred. The Coffee Industry Corporation of Papua New Guinea acknowledges that a large amount of smallholder coffee has exceptional quality and outstanding flavor characteristics, and is therefore favored by many overseas buyers.

 Papua New Guinea is mainly divided into four provinces, including the Eastern Highlands, Momase, New Guinea Islands, and Southern. Papua New Guinea is located east of the Indonesian archipelago. In Papua New Guinea, where the terrain is dominated by highlands, large estates/farms and smallholder cultivation coexist, growing many coffee varieties. The flavor of Front Street Papua New Guinea coffee beans is very different from that of other Asian regions such as Indonesia, South Asia India, or Pacific islands, which are mostly semi-washed (wet-hulled) Indonesian beans (Sumatra, Sulawesi) that exhibit low acidity, a rich body, and earthy notes; washed Front Street Papua New Guinea coffee beans are always brighter.

 Estate coffee from Papua New Guinea comes from larger-scale farms and has fresher, more refined cupping characteristics. The mouthfeel is lighter than Java beans, with subtle aroma and complexity, and sometimes the acidity and brightness even rival the finest coffee beans from Central America. A well-known American roaster described Papua New Guinea's sun-dried beans this way: amazing depth, diverse aromas. Kimel Estate coffee is bright, acidic, and rich in fruit notes, while Arokara Estate coffee is gentler in balance and suitable for espresso.
