Madal Bal Syrup uses neera from several Southeast Asian palm species, including the Coconut Palm, the Arenga and Kitul Palms of the rainforests, the Nipah Palm of the swamps and marshes, and the Palmyra Palm of northern Sri Lanka. Madal Bal Syrup uses only neera produced on small farms, monitored by Madal Bal employees. This intensive form of production is certainly more expensive than large-scale plantation methods, but it ensures the highest-quality syrup and helps local communities develop by supporting family-based enterprises.
Some Canadian grade C syrup is also used in the Madal Bal Syrup. The Acer Saccharum, or Sugar Maple tree, is one of over 75 varieties of maple tree in North America and must be about 40 years old before it can be tapped. The Sugar Maple only produces sap within a 4 to 6 week period between March and April. It takes freezing cold nights and warm days for the sap to run. At this time the forests are still covered by several feet of snow, and thus harvesting the sap is a cold and arduous task.
