It has never faltered. The late Walter Mathagu always produced coffees that were perfectly ripe and sweet. Even as weather patterns challenged, they never overcame him. Year after year, the crop is exquisite, proving again and again to be the Grand Cru of coffee. Walter's legacy continues through his family - his sons, Peter, Jason, and Patrick Mathagu now run this great farm. Walter was the small farmer pioneer of quality coffee in Kenya and a consummate craftsman until his passing in 2021. He was an agricultural officer serving the government of Kenya for seventeen years before retiring in 1987. More than anyone, Walter put the Kirinyaga coffee region on the map. He raised small farmer awareness to what is possible and brought seekers of great specialty coffee in growing numbers to his area. Taking inspiration from their family, Mamuto means “father, mother, and children.” Walter and Abishag have six children: three boys and three girls. They named the farm by combining the first two letters of Mathagu (family name), Muthoni (his wife’s maiden name), and Toto (child in Swahili). We continue to buy Mamuto’s entire crop. It grows beneath the slopes of the 17,000-foot Mt. Kenya. The soil is deep red-orange, set amongst a lush green and very gently undulating landscape. The coffee is processed at the farm right through drying. After drying, it remains in parchment for approximately six weeks, resting in aerated bins before being transported for final milling and packaging. Kenya developed the most stringent processing and milling standards in the world. Mamuto is machine sorted, then hand sorted to remove any remaining blemishes. Beans are sorted into very narrow ranges of size in order to maintain even roasting. The top grade, AA, is comprised of the two largest sizes, followed by grade AB, the next two sizes. To experience Mamuto, roasted and brewed properly, is to drink coffee in every way comparable to the finest red wines. It's well-balanced with lively dark fruit notes that fully reflect the terroir. Farms around the world have tried to replicate it, but so far, none have come close to producing the lush flavors Kenya is capable of. George and Jenny travel annually to visit the farm and the Mathagu family around harvest season in late December. It's one of our most cherished relationships. Over the years, we’ve collaborated with Mamuto on adding drying beds, conditioning bins, and a storage building as well as introducing moisture meters all for the sake of refining their process to push quality forward. Most recently, we’ve embarked on a DNA project of Mamuto’s coffee beans. Our goal is to help preserve one of the most special and elusive flavors in coffee and become a source of learning for others along the way. We look forward to updating you on this exciting journey.
