#0031 PROTOKOL RAKTALU

Breaking down coffee quality to the core has been a passion for small micro roasters like Arkib. Since 2021, we have been heavily involved at the farm level to indulge in coffee farm practices and coffee processing methods. This led to our collaboration with a small coffee producer to create custom-processed coffee for Arkib and brand it under the name of the Protokol series. The whole collection features specific coffee processing methods designed by Arkib to highlight the uniqueness of the processing while retaining the origin's signature taste.

This is our processing method batch no. #0031, called Raktalu, with 72 hours of anoxic submerged process and 120 hours of natural anaerobic. It went through two different kinds of processes of cold and hot fermentation, which create tension in the flavor profile, stretching the capacity of Sumatra coffee. Submerged fermentation is a fermentation process that happens with zero oxygen molecules. Selected red cherries were put in a tank of cold water and left over to ferment for 120 hours.It allowed certain strains of microbes present that shaped the coffee flavor. The cold water temperature slows the fermentation process, which indirectly contributes to flavor depth. The coffee underwent a further 120-hour anaerobic treatment to increase its sweetness and natural taste.

The Protokol has come a long way with a huge result, and we couldn't be happier to taste Yani's current Raktalu lot.  The combination of cold and hot eliminates any trace of characteristic Sumatra flavor, resulting in a delicate and progressive taste profile. The fragrance and aroma are mainly driven by tropical fruit sensations such as grape, mangosteen, and dried mango. The fruity taste gives the perception of biting rich and juicy fresh plum. The texture is soft and smooth, similar to drinking milk chocolate. Raktalu has a nuanced and progressive taste, with notes of assam baldu merah, purple raisin, canele, and coco crunch. We never imagined a coffee could be so wonderful, and Raktalu is pure delight for specialty coffee enthusiasts.
