Si Ji Chun (四季春, Sì Jì Chūn — “Four Seasons Spring”) is a Taiwanese oolong cultivar that produces fragrant, floral tea across all four annual harvesting seasons rather than just spring — earning the name that emphasizes its year-round spring-like aromatic freshness. Developed in the Muzha district of Taipei in the 1980s, it is now one of Taiwan’s most widely grown commercial oolong cultivars, producing accessible, budget-friendly oolongs with consistent florals.
In-Depth Explanation
What makes it distinctive:
Most fine oolongs are harvested primarily in spring (and perhaps autumn), with winter and summer productions considered lower quality. Si Ji Chun is a cultivar specifically bred for multi-season production with consistent aromatic quality — it develops floral fragrances comparable to spring productions even in summer and winter harvests. This makes it commercially valuable as a year-round supply product.
Flavor profile:
| Property | Si Ji Chun |
|---|---|
| Oxidation | Typically 20–30% — light to medium |
| Leaf form | Ball-rolled; medium-tight; green to yellow-green |
| Liquor color | Clear yellow-green |
| Aroma | Strongly floral; lily, freesia, light osmanthus; fresh |
| Flavor | Floral sweetness; light body; smooth; minimal bitterness |
| Body | Light to medium |
| Finish | Floral; clean; moderate length |
Cultivar origin:
Si Ji Chun was developed in the Shiding/Muzha area of New Taipei City in the 1980s, reportedly through selective propagation from a spontaneous seedling cultivar that demonstrated unusual multi-season aromatic quality. The cultivar was subsequently distributed widely throughout Nantou, Chiayi, and other growing areas. Today it is one of Taiwan’s most widely planted commercial tea varieties.
Price and market position:
Si Ji Chun is considerably more affordable than high-elevation oolongs such as Alishan or Lishan varieties. At low elevations (below 500m), it provides reliable aromatic commercial oolong at accessible price points, making it one of the most exported Taiwanese oolongs in the budget-friendly tier. At mid-elevations (700–1,000m), higher-quality Si Ji Chun is produced.
Comparison with other Taiwanese cultivars:
| Cultivar | Character | Price range |
|---|---|---|
| Jin Xuan (TRES No.12) | Milk-oolong; creamy; dairy note | Mid |
| Si Ji Chun | Multi-season; floral/lily | Budget to mid |
| Qing Xin (Green Heart) | Classic high-mountain; complex floral | Mid to high |
| Baozhong | Lightly oxidized; fresh floral twists | Mid |
History
Si Ji Chun was developed in the Muzha area north of Taipei in the 1980s by local farmers who recognized the commercial opportunity of a multi-season aromatic cultivar. Unlike many Taiwanese oolongs that use the traditional Qing Xin (Green Heart) cultivar grown at high altitude, Si Ji Chun was designed for wider geographic versatility. Its rapid adoption across multiple growing regions accelerated through the 1990s as Taiwan’s specialty tea export market expanded.
Taste Profile
Si Ji Chun is noted for its bright, undeniably floral aroma — lily, freesia, and light osmanthus are common descriptors. It is one of the most fragrant Taiwanese oolongs and drinks smoothly without astringency. Recommended brewing: 90°C water, gongfu style, 30–45 seconds per infusion; gives 4–6 good infusions.
Common Misconceptions
“Si Ji Chun is lower quality because it’s cheap.” It is a high-yielding commercial cultivar and consistently less expensive than single-harvest high-mountain oolongs, but within its category (affordable floral Taiwanese oolong) it is reliable and genuinely aromatic. It serves a different market segment, not an inferior one.
