"Ninety Plus" does not refer to all coffees scoring above 90 points in evaluations. Good coffee appears one year and may be absent the next. Sometimes it emerges from different estates and possesses various flavor characteristics. "Ninety Plus" refers to a premium coffee series of 13 flavor profiles. These coffees come exclusively from Ninety Plus Coffee, an American specialty coffee creator. They are all heirloom varieties from Ethiopia, cultivated to maturity in ecological environments and processed to artistic standards for flavor optimization. The processing is Ninety Plus's specialty - they separate these coffees by variety, microclimate, and harvest timing, tasting each one individually and designing specific processing methods for each flavor profile, much like how major fashion designers approach their craft. They devote meticulous research and heartfelt effort to complete each piece, creating works that approach artistry. Natural products undergo extensive refinement and improvement before being presented in their most beautiful form.

90+ beans use a completely different naming convention compared to typical specialty beans. They don't include region or estate names; instead, each coffee is named according to its flavor profile. For example, "Zhuhmang" means "best approach" in the local dialect. Starting from a flavor concept, they name the coffee, then move to selecting regions and partner farms. This demonstrates that 90+ is a brand with a boutique business approach.

Ethiopia's Coffee Regions

In Ethiopia, you can find various coffee cultivation methods: from vast wild coffee forests and semi-developed lands to traditional small plots and modern plantations. About 50% of coffee is grown at altitudes above 1500 meters. Based on these four different production methods, Ethiopia is divided into nine major coffee regions, including five specialty coffee areas: Sidamo, Yirgacheffe, Harrar, Limu, and Lekempti, plus four commercial coffee regions: Djimmah, Illubabor, Tepi, and Bebeka. Each region uses either natural or washed processing methods, and different processing affects the flavor. Currently, natural processing accounts for about 80%, while washed processing accounts for about 20%.

Natural processing is an ancient method that rarely achieves pure flavors. However, with 90+'s technical support, Drima Zede involves manually selecting only the most mature coffee cherries, with painstaking constant stirring during the natural drying process to ensure uniformity. The result is an exceptionally clean and transparent flavor profile with dramatic temperature variations. The fruit, floral, and oak barrel aromas are incredibly captivating!

Also an Ethiopian natural process coffee, Zhuhmang undergoes strict supervision and selection, avoiding the unpleasant earthy notes and high defect rates common in typical natural beans. Instead, it highlights the captivating sweetness that natural processing is renowned for. Zhuhmang's delightful fruit character inherits the enchanting aromas of traditional Ethiopian natural coffees, unreservedly expressing round, full-bodied sweetness with a lingering aftertaste and just the right amount of mouth-watering fruit acidity. Zhuhmang is also quite easy to brew daily. The beans themselves are rich in flavor, and whether using clean pour-over methods or rich siphon brewing, they beautifully express their inherent character.
