[ 3 ] Story
This time, I reached to Project Origin to source something special. Project Origin was founded by the 2015 World Barista Champion Sasa Sestic. They are known to source incredibly high-quality coffee from around the world while giving a positive impact to the coffee producers through sustainable practices and ongoing development to the community.
This CM coffee was introduced by Sasa at the world championship in 2015. Since then, the CM processed coffee has gained popularity among competitors.
So what is it?
‘CM’ stands for Carbonic Maceration. It is a process adopted from winemaking which utilize carbon dioxide and temperature/humidity control environment to accentuate the certain characteristic of coffee. It’s a bit like steroids on coffee. Currently, Project Origin offers 4 types of CM coffee which are: Diamond, Jasper, Amber, and Indigo. Each name represents specific flavor profiles.
This lot is called Amber #311 CM Natural.
So why Amber?
Because it shows a flavor profile of orange and yellow fruits with improved sweetness. This CM technique maximizes the delicacy and transparency of flavor.
