Sensory Dissection
Flavor
Assam
Assam is a full-bodied black tea from northeast India, grown in a hot river-valley climate. The cup is malty and robust with notes of honey, toasted grain, and dried fruit, plus enough strength to stand up to milk and sugar. Second-flush Assam adds a characteristic caramelized sweetness. It is the backbone of many breakfast blends, including English Breakfast.
Keemun
Keemun is China's most famous black tea, from Qimen county in Anhui. The cup is smooth and refined: cocoa and dark stone fruit up front, a hint of orchid florals, and a long, sweet finish with gentle smoke. It is lighter in body than Assam but more aromatic, and it forms the base of traditional English Breakfast blends.
