Assam tea is instantly recognisable. Bold, malty, and rich in aroma, it has long been a favourite in households around the world. But what makes Assam tea truly unique goes far beyond its flavour. It is the combination of environment, plant variety, and careful craftsmanship that defines its character.
If you’d like a broader understanding of Assam tea’s history, cultivation, and cultural significance, our Ultimate Guide to Assam Tea provides a full overview.
Assam’s Lowland Terroir
Most of the world’s famous teas, including Darjeeling, Chinese green teas, and Taiwanese oolongs, are grown at elevation, where cool mountain air shapes the flavour of the leaf. Assam is different.
Assam is one of the few major tea-growing regions in the world located in a tropical lowland valley rather than high mountains. Nestled in the fertile Brahmaputra valley and adjacent to the Dehing River, the region enjoys a combination of rich alluvial soils, abundant monsoon rains, intense humidity and long hours of sunlight. These lush, fertile conditions allow tea bushes to grow large, robust leaves packed with natural sugars, polyphenols, and aromatic compounds. To understand the importance of the Dehing River in the tea trade, explore our article about the Dehing River's Role in Assam's Tea Legacy.
This environment gives Assam tea its signature strength and malty flavour. Unlike high-altitude teas, which often exhibit delicate floral or grassy notes, Assam teas have a full-bodied character that stands up beautifully to milk and sugar, making them the backbone of many breakfast blends, and why single-estate Assam teas are so prized.
A Distinct Plant Variety: Camellia Sinensis var. Assamica
Assam’s unique flavour starts with the plant itself. While many teas use the small-leaf Camellia sinensis var. sinensis, Assam tea is primarily derived from the large-leaf assamica variety. These leaves are naturally broader, richer in polyphenols, and capable of producing a strong, malty brew.
The combination of the tropical lowland environment and the assamica leaf is what creates a tea that is both bold and nuanced, which is perfect for those who enjoy depth without harshness.
Crafting the Tea: From Garden to Cup
The flavour of Assam tea is not simply a gift of nature; it is meticulously crafted by skilled tea workers. At Dehing Tea, our gardens in Pengeri are family-run and our on-site tea factory allows us to oversee every step of production. This ensures that the integrity of the leaf is preserved, from harvest to final packaging.
In our factory, we produce orthodox and CTC black tea and also green tea.
Orthodox vs. CTC Production
Assam is known for producing both orthodox tea and CTC tea.
Orthodox tea is carefully hand-rolled or machine-rolled to preserve the whole leaf. When you think loose leaf tea, this is perhaps what you might visualise. Second-flush orthodox black teas are complex, sweet and have a layered depth and it is no surprise that they express the most highly prized and distinctive qualities of the Assam region.
CTC tea (Crush–Tear–Curl) is processed to create small pellets ideal for strong, brisk brews. This is common for Masala Chai tea, for example, which requires a strong flavour to balance the spices.

Green Tea
For green tea specifically, our production process includes careful reception and quality checks, steaming to halt oxidation, rolling to release the leaf’s juices and shape it, gentle drying, sorting, tasting, and finally packaging. Every step is designed to maintain freshness, preserve aroma, and showcase the natural qualities of the leaf. While green tea and black tea diverge in processing after picking, the care and attention at each stage of production ensures a consistently high-quality product.
The Role of the Factory
Processing choices influence the final cup dramatically. If you’re curious about how processing diverges across tea types, you can explore our guide on the difference between green tea and black tea, which explains how oxidation shapes the character of each tea.
Second Flush Assam Black Tea
Assam tea is harvested multiple times a year, but the second flush, typically harvested between May and June, produces the teas most celebrated and prized by connoisseurs. During this period, the leaves have matured, the sunlight is abundant, and the monsoon rains have nourished the bushes. The resulting tea exhibits deep maltiness, golden tips, and subtle sweetness, delivering a richness that cannot be replicated outside this region. Second-flush Assam black teas are considered the pinnacle of the region’s production.
A Unique Flavour Profile
When you brew a cup of Assam tea, what you experience is the culmination of terroir, leaf, and craftsmanship. The liquor is deep amber in colour, the body full and smooth, and the flavours layered with malt, honeyed notes, and hints of spice. This complex balance of strength and subtlety is what makes Assam tea distinctive and versatile.
Even within Assam, different estates produce unique expressions. At Dehing Tea, the careful management of our garden practices and factory processing ensures that every cup embodies the richness of the Pengeri region.

Why Assam Tea is Exceptional
The uniqueness of Assam tea is rooted in several key factors, all of which carefully come together to produce Assam’s signature teas:
• A tropical lowland terroir that produces robust, flavourful leaves.
• The large-leaf assamica variety, naturally strong and malty.
• Generations of craftsmanship, from careful plucking to precise processing at estate-run factories.
• Seasonal harvesting that captures the peak expression of the leaf.
• Meticulous attention in processing, whether the tea is orthodox black or delicate green, preserving the integrity and flavour of the leaf.
This combination of geography, plant, and care is what sets Assam tea apart, creating a tea that is bold, complex, and unmistakably Assam.
Colour, Strength and Body: The Signature of Assam
Unlike green teas or lightly oxidised teas, Assam black tea is known for three defining traits:
1. Deep Amber Liquor - A hallmark of well-made Assam tea, the liquor is a rich, glowing copper cup.
2. Full-Bodied Texture - A satisfying weight on the palate, with a smooth finish.
3. Brisk Energy - A lively, invigorating quality, especially in orthodox second flush teas.
These characteristics make Assam tea particularly versatile, equally suited to drinking plain or with milk.
Why Provenance Matters: Estate-Grown Assam Tea
Not all Assam tea is the same.
Estate-grown teas, such as those produced at Dehing Tea, offer consistent quality, transparent origin, careful leaf selection and traceable craftsmanship.
Because the tea is grown, processed and graded within the same estate, the integrity of the leaf is preserved throughout the entire process.
This is what allows a tea to fully express its terroir and sense of place.
At Dehing Tea, we are committed to showcasing the best that Assam has to offer, ensuring that every cup reflects the dedication of our family-run gardens and our estate-run factory.
