First Grade Dragon Well Green Tea vs. Biluochun Green Tea

When it comes to premium Chinese green teas, First Grade Dragon Well (Longjing) Tea and Biluochun Green Tea stand out as two of the most celebrated varieties. Both teas boast rich histories, unique flavors, and distinct production methods. Let’s explore their differences and similarities to help you decide which one suits your palate.

Origins and History

Dragon Well Tea, also known as Longjing, originates from Hangzhou in Zhejiang Province. With a history spanning over 1,200 years, it’s often referred to as the “National Tea of China.” The first-grade variety represents the highest quality, hand-picked from the earliest spring buds.

Biluochun, meaning “Green Snail Spring,” comes from Dongting Mountain in Jiangsu Province. Its name derives from the tea’s spiral shape resembling snail shells. This tea has been cherished since the Tang Dynasty (618-907 AD) and is renowned for its delicate appearance and fruity aroma.

Appearance and Processing

First Grade Dragon Well leaves are flat and sword-shaped, resulting from a unique pan-firing technique that preserves their vibrant green color. The processing involves careful hand-pressing against hot woks to create the characteristic flat shape.

Biluochun leaves are tightly curled into small spirals, covered with fine white hairs. The processing includes earlier harvesting of tender buds and a gentler heating process to maintain the delicate spiral form and preserve the natural white hairs.

Flavor Profile

Dragon Well Green Tea offers a mellow, chestnut-like flavor with sweet undertones and a smooth, lingering aftertaste. The first-grade variety has exceptional clarity and a refreshing vegetal note.

Biluochun presents a more floral and fruity character, often with notes of peach blossom and a slightly stronger aroma. The taste is brisk yet sweet, with a distinctive freshness that reflects its early spring harvest.

Brewing Methods

For Dragon Well, use water at 75-80°C (167-176°F) and steep for 1-2 minutes. The flat leaves will gracefully sink and rise during infusion, creating a beautiful visual experience.

Biluochun requires slightly cooler water (70-75°C or 158-167°F) and shorter steeping (30-60 seconds) due to its delicate nature. The spiral leaves unfurl dramatically, releasing their aromatic compounds.

Health Benefits

Both teas are rich in antioxidants, particularly catechins, which may support heart health and metabolism. Dragon Well is noted for its higher concentration of amino acids, contributing to its sweet taste, while Biluochun contains more aromatic compounds that may aid relaxation.

Which One to Choose?

If you prefer a nutty, smooth tea with historical prestige, First Grade Dragon Well is an excellent choice. For those who enjoy floral, aromatic teas with visual appeal, Biluochun might be more satisfying. Many tea enthusiasts find value in experiencing both to appreciate the diversity of Chinese green teas.

Ultimately, the decision comes down to personal preference. Why not try both and discover which one resonates with your taste buds?

  • High concentration of amino acids that contribute to its umami taste

The “first grade” designation indicates the highest quality of Longjing tea, harvested in early spring when the young tea leaves are at their most tender. The traditional pan-firing technique gives Dragon Well its characteristic flat shape and preserves its fresh, vegetal flavors.

Biluochun Green Tea

Biluochun, meaning “Green Snail Spring,” comes from Dongting Mountain in Jiangsu province. This exquisite tea is recognized by:

  • Tightly curled leaves resembling small snails
  • Distinctive fruity and floral aroma
  • Rich, complex flavor profile with notes of fruit and flowers
  • Downy white hairs covering the young leaves

Authentic Biluochun is harvested in early spring, with the finest quality consisting of one bud and one or two tender leaves. The tea’s name reflects both its spiral shape and the spring harvest season when it’s at its best.

Comparing These Premium Green Teas

Characteristic First Grade Dragon Well Biluochun
Leaf Shape Flat, sword-like Tightly curled, spiral
Aroma Chestnut, vegetal Fruity, floral
Flavor Mellow, sweet Complex, layered
Brewing Temperature 75-80°C (167-176°F) 70-75°C (158-167°F)
