The twirling brown leaves and golden tips of the world’s greatest Assam black teas yield lovely honey and malty flavors, a little like the maltiness of a good beer. Assams are also among the most assertive and brisk of the black teas. It’s no accident: The more quickly a tea is made, the brisker the body. And everything about Assam tea is fast. Continue on to learn more about the Assam tea region and the types of tea that are sourced from here.


Weather in the Assam Tea Region

Assam is India’s tea basket, a hothouse region that generates astonishing quantities of tea in just 6 weeks. Assam teas derive fromCamellia sinensis var.assamica, a large-leafed variety of tea discovered only in the 1830s by British botanist-adventurer Charles Bruce. The British were quick to establish massive tea plantations, which today grow many different clones of the wild original.

In Assam’s subtropical conditions, the plants suffer for nothing, least of all water: Assam is one of the wettest places on the planet. The mighty Brahmaputra River cuts right down the Y-Shaped northeastern region, brimming with melted Himalayan snows and the region’s rains. The weather is fairly consistent: It either pours down rain or it is sunny and steamy. In the tropical moisture, the tea bushes draw from the rich, alluvial soil to generate thick, big leaves from May through June. In the humid air, tea makers have to rush to process the tea.

Assam Tea Making Processes

Assam makers both wither and oxidize these leaves in less time than just about any other good tea. In contrast with oolong leaves, which benefit from multistage withering, or Darjeelings, which require a hard withering, Assam leaves are limp and ready for rolling after just 14 hours. Withering time is also altered based on the quality of leaf. Better leaves are withered harder (given more withering time). Withering is carried out in two stages, one allows natural changes inside  the leaf and the other reduces the moisture:

First Stage – Bio-chemical Withering: No chemicals are added, this refers to all that happens to many molecules already inside the tea leaves. Molecules like chlorophyll degrade and recombine with others. This creates some of the flavors you like. The green leaves are spread and kept at least 4-6 hours (from the time of plucking) in nylon wire-netting withering troughs. The leaves are spread 6-8 inches apart, to allow free access of air.
Second Stage – Physical Withering:Fresh air is pushed through fans for 6-8 hours to remove the moisture from the leaf. The average withering time is 10-14 hours. In the rainy season, to remove the surface moisture, heaters are used along with fans to blow hot air (32 – 35°C ) on the leaves for 2 hours.

Assam makers roll and oxidize their teas quickly as well. While most use CTC (cut-tear-curl) machines, a few great Orthodox Assam makers apply traditional rolling to macerate the large, thick assamica leaves. In this process, first they roll the leaves in large batches in strong machines that apply plenty of pneumatic pressure. The leaf morsels that are the first to break down are considered the best and are called “fines”. The remaining leaves are run through a conical sieve called adhool a second and third time. The thoroughly crushed leaves then oxidize very quickly, taking on strong, brisk flavors.

Orthodox Assams are the finest of the region, but they are risky to make. Indians drink primarily CTC tea, most often aschai, an intoxicating tea with spices and hot milk. But as a result, the domestic market for whole-leaf, Orthodox Assams is tiny. The best Orthodox Assams come from large estates that can afford to take a chance. Belying the usual assumptions about artisanal teas, some of Assam’s finest Orthodox teas come from these larger estates. These companies have helped improve the quality of the region’s teas dramatically in the last 50 years.


Golden Tip, CTC & Orthodox Assam Flavors

95% of the teas on the market in India are CTC teas. The aromas of CTC teas are simple and strong, with only a ghost of fruit flavors. The liquor is much darker, with much more body. Unlike Orthodox teas, CTC teas do not evolve and alter as you taste, but remain consistent. The flavor is comfortably stable but also somewhat predictable. For a pure CTC experience, try our  CTC Assam.

A step up in flavor from the CTC would be our  Irish Breakfast, a nice blend of broken orthodox Assams. This is a more complex brew than the CTC, but not as sweet as some of our tippier Assamese teas. Natural sweetness in tea comes from tips, or buds and the best Assam teas have some golden tips, both to give them more elegance and to drive up their price. We strive to offer a variety of tippy, orthodox teas for you to choose from. There is the  Mokalbari East Broken that is sweeter and more complex than the Irish Breakfast, with lots of body or the  Khongea Broken. My parents, Mike & Brigitte drink these teas most mornings.

Golden tip Assams are made of pure golden tips. Created within the last 30 years, these teas are so rare that they are only made on commission. We typically have to place an order before the harvest has even begun.

Golden tip Assams have less aroma from a very short withering. Unlike most Assams, golden tip Assams are barely rolled to preserve the delicate, expensive buds. The buds are then oxidized to a beautiful gold color when they are transferred to an oven to dry. If you’re interested in trying golden tip teas from the Assam tea region, we recommend trying our  Mokalbari Golden Assam or  Halmari Golden Tips.

Note to the reader: Each year, we see numerous samples from different Indian tea gardens. To this end, we may find that one garden's crop this year pales in comparison to last years, so we will find another whose tea piques our interest and palettes. Bearing this in mind, don't fret if you don't see your favorite Assam or Darjeeling garden from previous seasons, as the change in the estate means that we are committed to providing you with the best quality cup possible. You can see that we were impressed with Mokalbari East’s efforts this year.

India is an exciting country full of history and tradition. Our buyers always enjoy exploring the unique teas the region has to offer. Stay tuned as we explore the other tea growing regions of India. Read a few of our favorite posts below to continue learning about the exciting world of tea:
