Oolong & Black Tea
Oolong vs Black Tea Tasting
Guided oolong and black tea tasting: side-by-side comparison exercises to train your palate. How to taste oxidation, roast, terroir, and processing differences.
Introduction
The best way to understand the oxidation spectrum is to taste across it. This guide provides structured tasting exercises that will train your palate to identify the characteristics that distinguish different levels of oxidation and processing.
Exercise 1: The Oxidation Ladder
Brew the following teas side by side using identical parameters (3g per 150ml, 90 C, 3 minutes):
Light oolong (Alishan or Tie Guan Yin green style, ~20% oxidation): Note the floral aroma, buttery mouthfeel, and sweet, clean finish. The liquor should be pale gold-green. Medium oolong (Dong Ding or Dan Cong, ~40-50% oxidation): Notice how fruit notes emerge — peach, stone fruit — and the body thickens. The liquor deepens to amber. Heavy oolong (Oriental Beauty or Da Hong Pao, ~60-80% oxidation): Rich, complex, with dried fruit, honey, and mineral notes. The liquor is deep amber to light brown. Black tea (Keemun or Dian Hong, ~95% oxidation): Malty, sweet, brisk. The liquor is deep reddish-amber. Theaflavins provide the distinctive brisk tingle.
Exercise 2: Terroir Comparison
Compare two black teas of similar oxidation from different origins: Assam vs Darjeeling, or Keemun vs Dian Hong. Notice how identical processing produces different flavors when the raw material and terroir differ.
Exercise 3: Processing Impact
Compare a Chinese green-style Tie Guan Yin with a traditional roasted Tie Guan Yin. Same cultivar, same region, dramatically different processing — and dramatically different cups.
What to Focus On
Aroma: Hot dry leaf, hot wet leaf, and liquor. Color: Light reflects oxidation level — jade green through gold to amber and brown. Body: Light and crisp vs thick and coating. Astringency: Soft and smooth vs brisk and drying. Finish: How long does the flavor persist? What develops in the aftertaste?
Building Your Reference Library
With each tasting, you are building an internal catalog of sensory references. Over time, you will be able to blind-taste a tea and estimate its oxidation level, origin style, and processing quality with surprising accuracy.
