The Inevitable Processing of All Green Tea
The word "processed" can sometimes have a negative connotation, suggesting artificiality or heavy modification. However, when it comes to green tea, processing is not only standard but also essential to its very definition. Unlike black tea, which is made from oxidized tea leaves, green tea's unique color, flavor, and antioxidant properties depend on a process that intentionally halts oxidation. Bigelow Tea, like all reputable tea producers, implements specific processing methods to achieve its characteristic smooth and delicate flavor profile.
The Purpose of Processing
At the heart of green tea production is the need to inactivate the enzymes that cause oxidation. The fresh leaves of the tea plant, Camellia sinensis, begin to oxidize the moment they are plucked, turning dark and developing a different flavor profile, similar to what happens when you slice an apple. To prevent this, the freshly picked leaves must be heated quickly in a process known as "fixing" or "kill-green". This step is what distinguishes green tea from other varieties like black or oolong tea.
The Standard Steps of Green Tea Production
While specific methods can vary, the overall journey of green tea from plant to cup generally follows a series of controlled steps. Bigelow's commitment to quality involves close work with farmers to ensure these steps are meticulously followed for the best results.
- Plucking: Only the youngest leaves and buds are harvested for high-quality green tea, as they contain the highest concentration of desirable compounds.
- Withering (Optional/Minimal): A slight withering might occur to reduce some moisture, but this is kept very brief compared to black tea production to prevent significant oxidation.
- Fixing: The crucial step of halting oxidation. This is typically done through steaming (common in Japan) or pan-firing (common in China). Bigelow states they use a special heating method to achieve this.
- Rolling: The fixed leaves are rolled, which shapes them and breaks down cell walls to release flavors and oils. This enhances the flavor and appearance.
- Drying: The leaves are dried to remove the remaining moisture, ensuring they are stable for storage and have a long shelf life.
- Sorting and Packaging: The dried leaves are sorted by size and quality before being packaged, often in foil pouches to maintain freshness, as Bigelow does for its products.
Bigelow's Decaffeination Process
For its decaffeinated green tea, Bigelow uses an additional processing step. They employ a natural carbon dioxide (CO2) process to remove caffeine. In this method, moistened tea leaves are treated with heat, pressure, and natural CO2 gas. The CO2 bonds with the caffeine, which is then evaporated, leaving behind the delicate flavor and beneficial antioxidants. This process is considered gentle and effective for retaining the tea's desirable properties.
Bigelow's Green Tea Processing vs. Black Tea Processing: A Comparison
Understanding the contrast between green and black tea processing highlights why green tea requires specific handling. The key difference lies in the management of oxidation.
| Feature | Bigelow Green Tea | Black Tea (e.g., Bigelow's Earl Grey) |
|---|---|---|
| Oxidation | Immediately halted by heat (fixing). | Intentionally allowed to occur after harvesting. |
| Leaf Color | Retains its natural green color. | Turns a darker, brownish-black color. |
| Flavor Profile | Smooth, delicate, and not too grassy. | More robust, rich, and earthy flavors. |
| Polyphenol Content | Higher levels of catechins (like EGCG) are preserved. | Catechins are converted into complex compounds like theaflavins. |
| Key Step | Rapid heating (fixing) prevents enzymatic browning. | Controlled exposure to air to induce oxidation. |
Conclusion: Bigelow's Commitment to Quality and Control
In conclusion, it is accurate to state that Bigelow green tea is processed, but this is a deliberate and controlled part of creating green tea. The processing is not a form of over-refinement but a precise technique to preserve the leaves' natural qualities by preventing oxidation. For its decaffeinated products, Bigelow uses a natural CO2 process that gently removes caffeine while maintaining the tea's integrity. Ultimately, Bigelow's processing methods, combined with a focus on sourcing quality ingredients, result in a smooth, delicate, and high-quality product for tea drinkers. The next time you enjoy a cup of Bigelow green tea, you can appreciate the craftsmanship involved in preserving its unique character.
