Scientific studies proved that tea leaves from Pu’Er trees contain more polyphenolic organic compounds, which are the most powerful antioxidants than tea leaves from other regions. Sheng pu’er strengthens the cardiovascular system, vitalizes the nervous system, supports brain activity, reduces blood pressure, and has anti-inflammatory properties.

ABOUT
7566 (AN I) occupies a special place in the history of AN SHIM TEA PRODUCTION as our first truly successful Sheng Pu'Er blend. Created in 2022, the project began as an experiment inspired by a simple but ambitious idea: combining different aged Gu Shu Mao Cha from our warehouse to create a tea with greater balance, complexity, and depth than any single material could provide on its own. What started as a blending exercise soon became the beginning of an entirely new direction in our tea production.
While blending has long been a fundamental part of traditional Pu'Er production in China, where many famous recipes combine material from different regions, harvests, and grades, this approach remains relatively uncommon in Vietnam. The modern Vietnamese Pu'Er industry developed much later and has largely focused on single-origin productions, particularly when working with ancient tea tree material. As a result, most Vietnamese ancient tree teas are produced and marketed as individual regional expressions. With 7566, we chose a different path, exploring how carefully selected Vietnamese materials could be combined to create something greater than the sum of its parts.
The blend consists of ancient tea tree Mao Cha sourced from several mountain regions and provinces of Northern Vietnam. The materials were harvested in different years and then aged separately before being blended. The average age of the Mao Cha used in the recipe is approximately five years, while the average age of the tea trees themselves is around 350 years. This combination of mature material, ancient trees, and multiple origins creates a profile that is both highly complex and remarkably balanced, combining the strengths of different terroirs into a single tea.
The creation of the final recipe required numerous experiments, tastings, and adjustments. After countless sessions evaluating different combinations, we arrived at a composition that expressed exactly what we were seeking: sweetness, structure, complexity, mountain character, and harmony. We named the tea 7566 after the approximate distance in kilometers between Riga and Hanoi. While separated by thousands of kilometers, our shared passion for tea, friendship, and collaborative projects has continued to bring us together year after year. The name serves as a reminder that distance means very little when people share the same dedication and vision.
In many ways, 7566 symbolizes the beginning of a completely new chapter in our tea journey. From the earliest days of pressing small experimental cakes in a kitchen environment to the construction of our own factory in Hà Giàng in 2025, this tea reflects the evolution of our ideas, ambitions, and capabilities. It represents not only a tea recipe but also a story of persistence, creativity, and the desire to explore new possibilities within Vietnamese tea production.
Due to the unique composition of aged materials used in the blend, 7566 is impossible to reproduce. The specific Mao Cha that forms the foundation of this tea no longer exists in the same quantities or conditions, making every cake a limited snapshot of a particular moment in our production history. With more than ten years of cumulative storage represented within its various components, the tea displays a beautiful semi-aged Sheng Pu'Er profile, combining the energy of mountain tea with the smoothness and integration that only time can provide.
TERROIR
Unlike traditional single-origin teas, 7566 (AN I) was intentionally created from ancient tea tree material sourced from several mountain regions across Northern Vietnam. The blend brings together teas from different provinces, altitudes, ecosystems, and harvest years, allowing the strengths of each terroir to complement one another. Rather than expressing a single location, the tea reflects a broader portrait of Northern Vietnam's ancient tea tree heritage and demonstrates the remarkable diversity that exists within the region.
The materials used in the blend originate from mountain areas where ancient tea trees continue to grow at elevations ranging from 1,000 to over 2,000 meters above sea level. These regions are characterized by cool mountain climates, abundant rainfall, frequent mist, significant day-to-night temperature variation, and mineral-rich soils. Such conditions encourage slow leaf development and contribute to the accumulation of aromatic compounds, amino acids, and minerals that give ancient tree teas their depth, complexity, and aging potential.
The ancient tea trees used throughout the blend average approximately 350 years of age. Growing within diverse mountain ecosystems and largely free from intensive agricultural intervention, these trees develop deep root systems capable of drawing nutrients and minerals from multiple soil layers. This contributes to the rich texture, pronounced minerality, and exceptional persistence found throughout the tea session.
Each terroir contributes its own personality to the final composition. Some materials bring floral elegance and sweetness, while others contribute strength, minerality, structure, fruit character, or long-lasting aftertaste. Through careful selection and blending, these individual characteristics become integrated into a more complete and balanced expression.
ORGANOLEPTICS
The dry leaves display a mature and elegant appearance, consisting of ancient tea tree leaves and silvery buds that have developed additional depth through years of natural aging. Their color ranges from olive-green and bronze tones to deeper shades of amber and brown, reflecting the diversity of origins and harvest years incorporated into the blend. The aroma of the dry leaf is rich, refined, and highly layered, offering notes of wild honey, dried apricots, orchard fruits, mountain herbs, sweet wood, wildflowers, and gentle medicinal nuances. In a preheated gaiwan or teapot, the fragrance becomes increasingly complex, revealing additional layers of dried fruits, forest honey, pine resin, sugarcane, warm spices, aged wood, and mineral undertones. The maturity of the material is immediately apparent, yet the tea retains the vibrancy and freshness characteristic of carefully stored semi-aged Sheng Pu'Er.
The liquor is bright, clear, and luminous, displaying a deep golden-amber color. The aroma of the infusion is harmonious and expressive, combining notes of honey, dried fruits, wildflowers, mountain herbs, ripe stone fruits, sweet wood, and subtle resinous nuances. The texture is exceptionally smooth, thick, and rounded, coating the palate with richness while maintaining clarity and precision. The taste opens with pronounced sweetness before gradually revealing layers of dried apricots, honey, sugarcane, baked fruits, floral nectar, medicinal herbs, sweet wood, and mineral complexity. The careful blending of different aged materials creates remarkable balance, allowing no single characteristic to dominate the session. Instead, floral, fruity, herbal, mineral, and woody notes continuously interact and evolve throughout multiple infusions.
The aftertaste is long, deep, and highly persistent, with returning sweetness gradually filling the mouth and throat. Notes of honey, dried fruits, mountain herbs, and mineral freshness remain present long after each sip, creating a beautiful and sustained Hui Gan. As the session progresses, the tea becomes increasingly integrated and refined, revealing the benefits of both aging and thoughtful blending. In the empty cup, the aroma remains intensely fragrant, offering lingering notes of forest honey, dried apricots, sweet wood, wildflowers, pine resin, sugarcane, and subtle medicinal undertones.

"7566" Sheng Pu'Er production by AN SHIM TEA
4K Timelapse Video
"Years later, our passion for blending ancient tea tree material led us far beyond what we originally imagined. What began as a small experiment with 7566 eventually evolved into a complete philosophy of creating balanced, expressive, and character-driven Sheng Pu'Er blends. Along the way, several of these projects received international recognition, including Gold Medals at prestigious tea competitions, confirming our belief that thoughtful blending can be just as meaningful as celebrating a single origin.
As new recipes emerged, we decided to name them AN II, AN III, AN IV, and so on, as a tribute to the name of our companies. The word "AN" appears throughout many Asian languages and is commonly associated with peace and calmness. These values have always been at the heart of AN SHIM TEA. Through our work, we strive to bring more peace to people's hearts and minds, and we sincerely hope our teas are able to do the same.
Over time, we realized that 7566 was not simply our first successful blend. It was the true beginning of this journey. For this reason, we later gave it a second name: AN I. Looking back, it is easy to see that many of the ideas, techniques, and principles that define our current blending philosophy were already present in this very first recipe.
Every year, we travel throughout the mountains of Northern Vietnam, tasting countless teas, exploring ancient tea forests, and searching for the finest material available. From these discoveries, we carefully select and combine exceptional teas to create the next AN blend. Each recipe is unique, impossible to replicate exactly, and reflects a particular moment in time, a specific harvest, and a distinct vision of what a great Sheng Pu'Er can be.
If AN I represents the beginning of this story, we warmly invite you to continue the journey by exploring our later creations, including the award-winning AN II (2023), as well as AN III (2024) and AN IV (2026). Together, they demonstrate how diverse, complex, and fascinating the world of Vietnamese Sheng Pu'Er can be, while sharing the same philosophy of balance, harmony, and respect for ancient tea tree material."
