History

Sejak (세작, 'sparrow's tongue') is one of Korea's most treasured teas, named for the small, tender leaves that resemble a sparrow's tongue. Korean tea cultivation dates back to the Silla dynasty (57 BCE–935 CE), with Buddhist monks playing a central role in its spread. The Hadong region, nestled along the Seomjin River at the foot of Jirisan Mountain, is considered the birthplace of Korean tea, with wild tea trees said to have been planted from seeds brought from China in 828 CE. Sejak represents the second pick of spring, harvested after Ujeon (first pick) but still prized for its delicate quality. Korea's tea culture experienced near-extinction during the Japanese occupation but was revived in the 20th century by monks and scholars like the venerable Hyodang.

Processing

Sejak leaves are hand-picked in late April, selecting only the bud and one or two young leaves. Korean green tea processing differs from both Chinese and Japanese methods - the leaves are pan-fired in an iron cauldron (deokeum) multiple times, with hand-rolling between each firing. This repeated firing-and-rolling cycle (typically 7–9 rounds) produces a distinctively smooth, nutty character without the grassiness of Japanese steaming or the sharp roast of Chinese wok-firing. The leaves are then dried slowly to preserve their delicate flavor.

Tasting Notes

Appearance

Small, tightly rolled dark green leaves with a slight twist. When brewed, the liquor is a clear, pale yellow-green with excellent clarity.

Aroma

Delicate and inviting - toasted chestnuts, fresh cut grass, and a hint of ocean breeze. Less vegetal than Japanese green teas, more subtly sweet.

Taste

Smooth and round with a pronounced nutty sweetness, gentle vegetal notes, and a clean, lingering finish. Remarkably low in astringency with a natural umami depth that builds across infusions.

Brewing Guide

Western Style

  • Leaf: 3g per 200ml
  • Water: 70–75°C (158–167°F)
  • Time: 1–2 minutes
  • Infusions: 3–4 infusions

Gongfu Style

  • Leaf: 5g per 100ml
  • Water: 70°C (158°F)
  • Time: 30s first, +10s each
  • Infusions: 4–6 infusions

Step-by-step

  1. Heat the water. Bring fresh water to 70–75°C (158–167°F). Korean tea tradition emphasizes using water that has been boiled and cooled to the right temperature. Tip: Pour boiled water between cups to cool it - the Korean 'sik-him' technique reduces temperature roughly 10°C per transfer.
  2. Warm the teaware. Pour warm water into your teapot (dabgwan) and cups to preheat them, then discard. Tip: Korean celadon or porcelain teaware is traditional and helps showcase the pale green liquor.
  3. Add leaves. Place 3g of sejak in the dabgwan. Enjoy the dry leaf aroma before adding water. Tip: The dry leaves should smell of roasted chestnuts and fresh grass.
  4. First infusion. Pour water gently over the leaves and steep for 1–2 minutes. Pour out completely. Tip: The first infusion is the most delicate - savor the initial nutty sweetness.
  5. Subsequent infusions. Steep for progressively shorter times (30–60 seconds). Sejak rewards patience across 3–4 infusions. Tip: Each infusion reveals different layers - the later steeps tend to be sweeter and more rounded.

Buying Guide

What to look for

  • Small, uniform dark green leaves without yellowing or excessive stems
  • Origin from Hadong or Boseong - Korea's premier tea regions
  • Hand-picked (수제, suje) designation for highest quality
  • Harvest date - spring harvest (April–May) is most prized

Quality indicators

  • Ujeon (first pick) > Sejak (second pick) > Jungjak (third pick) in the Korean grading hierarchy
  • Wild-grown (야생, yasaeng) teas from old trees offer the most character
  • Organic certification is common and valued in Korean tea
  • Artisan-made teas from small producers tend to be superior

Price range: $15–30 for good quality, $40–80 for premium hand-picked, $100+ for wild-grown ujeon grade

Storage: Store in an airtight container away from light and moisture. Korean green tea is best consumed within 6 months of purchase. Refrigerate sealed packages for longer freshness.

Fun Facts

  • Korea's tea ceremony, called Dado (茶道), emphasizes simplicity, nature, and mindfulness - distinct from Japanese and Chinese ceremonies.
  • The Hadong region's wild tea trees are said to descend from seeds brought by the envoy Kim Daeryeom from Tang China in 828 CE.
  • Korean tea culture nearly disappeared during the Japanese colonial period but was revived by Buddhist monks in the mid-20th century.
  • Sejak translates to 'sparrow's tongue' because the tiny spring leaves resemble a bird's tongue in size and shape.
  • South Korea produces less than 0.1% of the world's tea, making authentic Korean teas genuinely rare on the global market.
