Black Tea
Black tea is defined by full oxidation. Through deliberate and complete exposure to oxygen, the tea leaf undergoes profound chemical transformation, resulting in depth, warmth, and robust structure.
What Defines Black Tea
Unlike green and oolong teas, where oxidation is limited or controlled, black tea allows oxidation to proceed fully. This process darkens the leaf, stabilises the tea, and produces rich flavors ranging from malty and sweet to fruity, spicy, or brisk.
Core Processing Principles
- Withering: Fresh leaves lose moisture and become pliable.
- Rolling or crushing: Cell walls are broken to accelerate oxidation.
- Full oxidation: Leaves oxidise completely, transforming polyphenols.
- Drying: Heat halts oxidation and stabilises the tea.
Major Black Tea Style Families
- Chinese black tea: Often sweet, smooth, and aromatic. Examples include Keemun and Dian Hong.
- Indian black tea: Brisk, malty, and bold. Examples include Assam and Darjeeling.
- Blended black tea: Designed for consistency and strength, such as breakfast-style blends.
Caffeine & Character
Black tea generally contains a moderate to higher level of caffeine. Due to full oxidation, its energy is often perceived as steady and warming, making it suitable for morning or daytime consumption.
Storage & Aging
Compared to green and lightly oxidised teas, black tea is relatively stable. When stored airtight, away from moisture and strong odors, it maintains quality over time, though it is not typically aged for transformation.
