Siamang Blend Natural


Siamang Blend comes from quite the giving trees. Giving some of the most well-known coffee in the area, they also have a rich history in how they got here and how they’ve impacted the lives of those who farm it. Onan Ganjang, named after the village where it was discovered, naturally crossed with the Bourbon Strain over time to give the farmers a reliable and enjoyable crop year after year.
