The Foundation of Premium Pu-erh: Menghai Tea Factory’s Dedicated Tea Gardens
When it comes to authentic, high-quality Pu-erh tea, few names command as much respect as Menghai Tea Factory. As the birthplace of the renowned "Dayi" (Da Yi) brand, this historic manufacturer has long been at the forefront of China’s Pu-erh industry. A key pillar of its consistent excellence lies in its strategic ownership and management of raw material bases — most notably, two large-scale plantations located in Bulang Mountain and Bada, both within Yunnan’s Xishuangbanna Prefecture.
Spanning a combined area of 20,894 acres, these tea gardens are not just vast; they are carefully selected for their ideal ecological conditions. At elevations exceeding 1,700 meters, with year-round mild climates, abundant rainfall, and persistent mountain mist, the tea leaves grown here exhibit the hallmark characteristics of high-mountain teas: rich color, intense aroma, and complex flavor profiles. This natural advantage forms the foundation for the distinctive quality found in Dayi Pu-erh products.
Bada Base: Where Ancient Trees Meet Modern Cultivation
Located about 110 kilometers southwest of Jinghong, the Bada tea base sits near the legendary 1,700-year-old wild tea tree — a living symbol of Yunnan’s deep tea heritage. The region’s pristine environment, untouched by industrial pollution, supports organic growth patterns that enhance leaf quality.
Teas from Bada are known for their bright golden infusion, floral and honey-like fragrance, and a clean aftertaste marked by swift huigan (returning sweetness). These attributes make Bada-sourced leaves one of the primary ingredients in many of Menghai Tea Factory’s signature blends.
The base was established in response to growing market pressures during the late 1980s when competition for raw materials intensified. Recognizing the need for self-reliance, then-Party Secretary Yu Zhengcai spearheaded an initiative to transform unused state-owned wastelands into productive tea fields. With support from local government officials and decades of refinement, Bada evolved into a model of sustainable, high-altitude cultivation.
Bulang Mountain Base: A Natural Sanctuary for Tea Excellence
Situated within the Bulangshan Forestry Farm — adjacent to the famous tourist destination Daluo — this plantation thrives amidst dense forests and broad-leaved woodland ecosystems. The interwoven landscape of trees, streams, and tea bushes creates a true eco-tea garden, resembling a real-life Shangri-La.
Covering over 10,000 productive acres, the Bulang base benefits from its proximity to old-growth forests and favorable microclimatic conditions. Its teas are characterized by robust buds, thick liquor, and a powerful "Bulang character" — bold, slightly bitter with rapid sweet rebound, and layered with notes of plum and orchid.
Due to its adjacency to Laoman’e, one of Pu-erh’s most revered villages, Bulang-grown leaves inherit similar terroir qualities. In fact, early spring harvests from this base now fetch prices between ¥500–600 per kilogram, reflecting both scarcity and demand. Local farmers who once lived in modest homes now enjoy modern comforts — a testament to how tea cultivation can uplift rural communities.
“We envisioned a stable supply chain rooted in sustainability. Today, seeing our farmers thrive confirms that vision.”

Behind the Scenes: How Menghai Ensures Quality from Leaf to Cup
Beyond owning land, Menghai Tea Factory employs a multi-tiered approach to raw material acquisition:
- Owned Estates: Bada and Bulang bases provide traceable, consistently high-grade leaves.
- Cooperative Partnerships: Hundreds of affiliated primary processing stations across key regions ensure access to diverse terroirs.
- Strict Supplier Standards: Independent producers must meet rigorous hygiene, technical capability, and ethical sourcing benchmarks.
Each batch undergoes systematic grading — from Special Grade to Level 10 — based on physical appearance and internal quality. For unique or exceptional lots that don’t fit standard classifications, a special procurement process is applied, maintaining flexibility without compromising integrity.
The Secret Weapon: Anonymous Quality Evaluation
One of Menghai’s most innovative practices is its "password evaluation" system — a blind tasting protocol designed to eliminate bias. Here's how it works:
- Incoming tea samples are assigned random codes at the warehouse.
- These coded samples are sent to a dedicated evaluation room.
- A rotating panel of three experts assesses each sample against official reference standards.
- No evaluator knows the origin or supplier of any sample.
This process ensures fairness and objectivity in procurement decisions. If disputes arise, a formal review mechanism is triggered. Such transparency strengthens trust among suppliers and reinforces the factory’s commitment to merit-based selection.
Frequently Asked Questions (FAQ)
Q: Is all Dayi Pu-erh made from tea grown in Menghai-owned gardens?
A: No. While the Bada and Bulang bases supply premium raw materials, Menghai also sources from trusted partner farms across Yunnan to meet production demands and diversify flavor profiles.
Q: Can consumers identify if a tea comes from Bada or Bulang base?
A: Officially labeled estate-specific cakes do exist, especially in limited editions. Otherwise, precise origin is often blended or undisclosed. However, experienced drinkers may recognize stylistic traits associated with these regions.
Q: Are Menghai’s tea bases organic?
A: Though not all certified organic, both bases emphasize ecological balance and minimal chemical use. Many areas follow near-organic practices due to forest integration and natural nutrient cycling.
Q: Why does Menghai control its own plantations?
A: Owning land ensures supply stability, quality consistency, and resilience against market fluctuations — critical for maintaining brand reputation and long-term growth.
Q: What makes Menghai tea stand out in flavor?
A: Known for its boldness and depth, Menghai Pu-erh typically features pronounced bitterness that quickly transforms into sweetness — a hallmark known as "Menghai character." This balance stems from regional climate, soil composition, and expert blending techniques.
The Broader Impact: Culture, Economy & Sustainability
Menghai County isn’t just a tea producer — it's a cultural epicenter. Home to ancient tea trees over 1,700 years old and recognized as a cradle of global tea civilization, it hosts the annual Menghai Tea King Festival, celebrating local heritage through competitions, ceremonies, and community events.
The county boasts over 46,000 acres of ancient tea gardens, contributing to its title as China’s largest Pu-erh processing hub. With more than 600 primary processing sites and over 100 refined factories, including major players clustered in industrial parks, Menghai continues to shape the future of Pu-erh on a national scale.
Moreover, integrating tea culture with tourism has become a strategic focus. Initiatives like eco-tourism trails through old-growth tea forests aim to preserve natural resources while boosting local economies.
Final Thoughts: The Legacy Lives On
Menghai Tea Factory’s decision to establish proprietary raw material bases wasn’t merely economic — it was visionary. By securing land, investing in infrastructure, and empowering local communities, they built a legacy rooted in sustainability and quality.
Today, whether you're sipping a vintage 7542 or exploring new releases under the Dayi label, you’re experiencing the fruits of decades-long dedication — from soil to shelf.
Pu-erh isn’t just about age or origin; it’s about intention. And in Menghai, that intention remains clear: to craft teas that honor tradition while embracing progress.
