Upper Assam produces some of the world's finest black teas, harvested from Camellia sinensis var. assamica in the fertile Brahmaputra Valley. The tea here is bold, malty, and deeply full-bodied, with a bright amber color and high polyphenol content that has made it the global benchmark for breakfast blends.
Beyond the cup, our extract delivers a high-purity ingredient for skincare, supplements, and functional beverages. Available as a standard extract or in decaffeinated form, with customizable solubility profiles for any formulation.
Highlights
Polyphenol content averaging 134 mg/g, ranging from 83 to 184 mg/g for high antioxidant performance
Caffeine averaging 30 mg/g, with a fully decaffeinated SKU available
Sourced exclusively from the Brahmaputra Valley in Upper Assam
Available oil-soluble, water-soluble, deodorized, and water-dispersible
Used across functional F&B, nutraceutical supplements, and cosmetic skincare
