About this tea

Formosa Oolong represents Taiwan's traditional oolong style, a category rather than specific origin, encompassing the island's classic 40-60% oxidized teas. The name 'Formosa' (Beautiful Island) was given by Portuguese sailors in 1544 and became synonymous with quality oolong during Taiwan's late 19th-century tea boom. These teas established Taiwan's reputation when John Dodd first exported them to New York in 1869, where they commanded premium prices.

Produced throughout Taiwan's tea regions, traditional Formosa oolongs undergo careful processing that balances oxidation to create complexity while maintaining freshness. The leaves are typically twisted rather than ball-rolled, allowing for even oxidation. Many are lightly roasted to add depth. This traditional style is increasingly rare as market preferences shift toward greener, high-mountain styles, making quality Formosa oolongs valuable for their representation of Taiwan's tea heritage.

The flavor profile offers sophisticated balance: medium body carries notes of ripe peach, apricot, and honey, underlaid with subtle roasted grain. The amber liquor has a silky texture with mild, pleasant astringency. Quality versions exhibit layers - fruity top notes, honey-like middle, and a clean, slightly woody finish. The oxidation level creates durability - these teas age gracefully, developing deeper, more complex flavors over years. Each infusion reveals different aspects of fruit, honey, and roast.

Brewing recommendations: Use 1 teaspoon (4g) per 250ml cup with water at 90°C (195°F), steeping for 2.5 minutes. The twisted leaves need room to expand. For gongfu style, use 7-8g per 100ml, steeping 45-60 seconds initially. This forgiving tea handles various brewing parameters well. Yields 5-7 flavorful infusions.

Perfect for all-day drinking or introducing newcomers to oolong. The balanced character makes it extremely food-friendly. Pairs excellently with dim sum, roasted poultry, fruit desserts, and nuts. Also wonderful with afternoon tea pastries. The medium oxidation provides enough body for cooler weather while remaining refreshing. This is heritage in a cup - a taste of Taiwan's tea history.
