A Serene and Clear Commitment: Global Anti Additive's Stringent 3-Star Certification
In a noisy era, true luxury is often the simplest. "Tseng's Tea" has always believed that the ultimate perfection of a good cup of tea lies in its "purity." This unwavering commitment has led us to be honored for three consecutive years with the highest award from the Anti Additive Clean Label Organization (AA Clean Label) – the "A.A. International 3-Star Anti Additive Certification."
What are the Hidden Standards of the A.A. 3-Star Certification?
This independent third-party certification, originating from Europe and America, is renowned for its scrutiny of global food safety governance, ensuring consumer protection. To achieve the highest "3-Star Certification," products must completely eliminate unnecessary chemical interventions during processing, meeting four "zero additive" audit requirements:
-
No added artificial colors or flavors
-
No added preservatives or bleaching agents
-
No added quality improvers
-
No added artificial sweeteners
Three consecutive years of uninterrupted certification is not merely an accumulation of numbers; it represents "Tseng's Tea's" most rigorous internalization and self-discipline regarding food safety. From the initial tender bud to the tea in your cup, we regard purity as our belief, offering the most reassuring foundation for every sip you take.
Purity Hidden in Taiwan's Mountains: Beyond Non-Toxic Organic, Pursuing Dual Food Safety Standards
Many tea enthusiasts are drawn to "Tseng's Tea" because of the unique terroir from specific regions. Our tea leaves are all cultivated in Taiwan's strictly managed, non-toxic, and organic first-tier tea gardens, where the unique geographical microclimate naturally nourishes the tea trees amidst clouds and dew.
"Since the production area is already non-toxic and organic, why do you still insist on international inspection?"
Because we deeply understand that unconditional trust can withstand the most meticulous scrutiny.
Non-toxic sustainability is our gentle commitment to the Taiwanese land that nurtures our tea trees; the A.A. 3-Star certification is our rational promise to every connoisseur. Through stringent international third-party audits, we have added a double guarantee of food safety to the beauty of our terroir. No matter how time flows, what you will always drink in "Tseng's Tea" is the purity of the land, absolutely free from chemical burdens.

Aged Natural Fragrance: An Island Miracle in Collaboration with the Green Leafhopper
Friends who encounter "Tseng's Tea" for the first time are often surprised by the delicate and lingering aroma after tasting it, and can't help but ask softly: "How can this tea be so fragrant? It's unlike anything I've tasted before! Is it really additive-free?"
This is a delightful misunderstanding. We always answer with reverence: "This is a perfect accident, elegantly conspired by us and nature."
In tea gardens completely free of chemical pesticides, tea trees and the ecosystem coexist harmoniously. Every specific season, the small sprites of Taiwan's low-altitude regions—the "green leafhoppers"—gracefully arrive.

Jassid Infestation: Nature's Gift of Olfactory Art
When fresh leaves are bitten (jassid-infested) by the green leafhopper, the tea tree, in self-defense, activates a mysterious defense mechanism, secreting unique natural defense compounds in its leaves. This mark of nature, under the keen perception of tea masters, undergoes precise fermentation and refined roasting, ultimately transforming into an intoxicating natural honey fragrance and elegant ripe fruit aroma.
This is not a precise fragrance formulated with chemical equations in a laboratory, but a sensory poem collaboratively composed by terroir, insects, tea trees, and artisans in a specific geographical and temporal context.
A Cup of Purity, a Tribute to the Aesthetic of Emptiness Coexisting with Nature
Because of no additives, we can see the original appearance of tea leaves; because of our dedication to perfection, we have refined the brand's soul with three consecutive years of the highest international standards.
What "Tseng's Tea" pursues is never just the flavor of a cup of tea, but a simple, high-end lifestyle ritual integrated with nature. The next time you quietly raise your cup and savor that lingering natural tea aroma, what you taste is the purity nurtured by the island's mountains, the gentle poetry left by the green leafhoppers, and the most steadfast and elegant assurance behind "Tseng's Tea's" three consecutive years of A.A. 3-Star certification.
