From the Vendor: A Kats classic! To formulate our world-class Red Maeng Da strain, we start by combining ultra high-quality White Vein Kratom sourced from the JongKong Region of Indonesia with Red Vein Kratom that grows naturally in the Borneo region. To achieve the desired alkaloid profile, the White Vein Kratom is dried outdoors for 48 hours with the leaves still stemmed. In parallel, the Red Vein Kratom is dried indoors inside burlap bags as part of a fermentation process that lasts for three days. After much experimentation, we’ve arrived at the ideal Red Maeng Da ratio of white vein to red vein: 40/60.
