About this tea

Black Dragon Oolong (Hei Long or Wu Long) represents the original dark style of oolong that gave the entire category its name - 'Wu Long' literally meaning 'Black Dragon' in Chinese. Legend tells of a tea farmer named Wu Liang (later corrupted to Wu Long) who discovered the oxidation process when distracted by a black dragon (or in some versions, while hunting a deer). When he returned to his picked leaves days later, they had partially oxidized, creating the first oolong. This traditional style emphasizes heavy oxidation and roasting.

Produced primarily in Fujian and Guangdong provinces, Black Dragon oolong undergoes 70-85% oxidation, placing it closer to black tea while maintaining oolong's distinctive processing. The leaves are heavily rolled and twisted, resembling the coiled body of a dragon. Traditional charcoal roasting, sometimes repeated multiple times over months, develops profound depth. This style predates the modern lighter oolongs, representing how oolong was originally made centuries ago. The dragon imagery reflects the tea's powerful, transformative character.

The flavor profile is bold and satisfying: dominant roasted notes of dark chocolate and coffee provide immediate impact, followed by caramel sweetness that balances the intensity. Woody, slightly smoky undertones add complexity without overwhelming. The texture is full-bodied and smooth, coating the mouth with pleasant astringency. Despite heavy roasting, fruit notes of baked plums emerge in later infusions. The finish is long and warming with malty sweetness. Multiple infusions reveal evolution from roasted to sweet to fruity. This is oolong in its most powerful form.

Brewing recommendations: Use 1 tablespoon (5g) per 250ml cup with water at 93°C (200°F), steeping for 2 minutes. The dark leaves need heat to fully open. For gongfu style, use 8-9g per 100ml, steeping 30-45 seconds initially after rinsing. Can yield 8-10 strong infusions. The robust character handles various brewing parameters well. Excellent both hot and cold-brewed.

Perfect any time of day due to its balanced, satisfying character. The bold profile makes it ideal for oolong newcomers transitioning from coffee or black tea. Pairs excellently with chocolate desserts, roasted meats, hearty breakfasts, and rich foods where its strength provides balance. Also traditional with dim sum where it cuts through oil and refreshes the palate. The dragon strength makes it perfect for cold mornings or when you need powerful, energizing tea. This is the original oolong experience - bold, transformative, and legendary.
