The NANA1807 Method | Iced Tea Preparation

The NANA1807® Method of Living Iced Tea
A living, slow and sensory preparation — between science, tradition and plant intuition.
The art of brewing a living, structured, beneficial iced tea.
A scientific, sensory and plant-respectful approach.

We have developed The NANA1807® Method , a 4-step technique, respectful of living things, which combines traditional know-how , scientific rigor and sensory pleasure .
1. Activate the Plant Essence
Unleashing the Intelligence of Plants
We start with a hot infusion ( 80–90°C for 3 to 4 minutes ), depending on the type of tea. This step awakens the plants' chemical intelligence and releases their essential aromas , including the essential molecules of tea:
-
Polyphenols (powerful antioxidants such as catechins)
-
Flavonoids and tannins , with anti-inflammatory and digestive properties
-
Theanine (a relaxing amino acid), mild caffeine , and aromatic volatile oils
Why this hot infusion?
Heat breaks down the cell walls of the leaves, allowing the extraction of active compounds that are only released above 70°C , particularly in green and black teas. Hot infusion awakens the heart of the leaf , where the tea's beneficial properties reside.
| Compounds | Role | Optimal temperature |
|---|---|---|
| Catechins (EGCG, ECG) | Powerful antioxidants, bitter if in excess | 70–85°C |
| Caffeine | Mild stimulant | 85–95°C |
| Théanine | Relaxing, balances caffeine | 70–90°C |
| Essential oils | Primary aromas | 60–85°C |
| Tannins | Structure and astringency | 85–95°C |
| Mineral Salts | Vitality, balance | 70–90°C |

2. Rest at Room Temperature
Preserving Molecular Balance
After being brewed hot, the tea should cool slowly to room temperature for 2 to 3 hours:
- Tannin softening
- Stabilization of volatile aromas
- Beginning of slow aromatic reactions
- Chemical equilibrium of the liquor
It is an alchemical pause, a suspended moment where nature continues its work.
Why this cooling step?
Sudden cooling (with ice cubes or immediate exposure to cold) freezes volatile aromas , contracts tannins , and creates an unstable precipitation of certain particles, altering the texture of the tea (astringency, bitterness, cloudiness).
By letting it rest, the liqueur is stabilized and a gradual aromatic maturation is allowed.
3. Slow Refrigeration
Refine the Taste Structure
The tea is then left to rest in a cool place for 5 to 7 hours . This step is not simply cooling; it is a phase of slow molecular transformation .
-
The tannins partially settle: the liqueur becomes softer and silkier.
-
Bitterness recedes in favor of secondary floral or vegetal notes.
-
The texture becomes rounder , more balanced , and more persistent on the palate.
This maturation process results in a more stable , more digestible beverage, with a better distribution of flavors and a natural sensory harmony .
During this refrigeration period, the cold allows:
- Natural settling of particles
- Clarification of the liquor
- Roundness of taste due to micro-precipitation of tannins
- Secondary aromatic evolution

4. Serve without ice cubes
Respect the liquor and the digestive system
Serving without ice avoids two major pitfalls:
-
Dilution of the flavor : the ice cubes melt quickly, altering the aromatic intensity of the liqueur
-
Digestive stress : too cold a liquid can cause vasoconstriction of the digestive mucosa , slowing down digestion and sometimes creating gastric or intestinal disorders.
By drinking a fresh, vibrant but not iced iced tea , we respect the internal harmony of the body and prolong the pleasure smoothly.
Serve chilled, between 6 and 10°C, without ice:
- Preserves the aromas and structure
- Promotes gentle digestion
- Avoid dilution and thermal shock
Note: below 5°C, the perception of aromas drops by 40 to 60% (source: neurogastronomy).
A Method Designed for Living Beings
The NANA1807® Method does more than just prepare iced tea:
It reveals the deep nature of Tea , activating its health benefits and releasing its full aromatic complexity.
It is based on:
- A phytotherapeutic approach : respecting the plant and its cycles
- A sensory approach : controlled extraction, slow infusion, balanced flavors
- An ecology of digestion : no sudden temperature changes, no shock to the body
A signature of the House
More than a method, it's a manifesto :
A plea for long-term thinking, quality , full presence , and listening to the cycles of plants.
Today it forms the basis of our summer Mint Tea for Peace ceremonies , our Mintealogy workshops , and our future collection of Living Iced Teas® .
Conclusion | Iced Tea, Re-enchanted
The NANA1807® Method is not a simple protocol: it is an art of living iced tea as a conscious experience.
A gentle alchemy between the hand, the plant, and time.
It restores the organoleptic complexity of the plant, preserves its benefits, and invites a tasting that respects the body, natural cycles and the memory of traditions.
Each sip becomes a gesture of peace.
Each cup, an offering to life.
