Guidelines for Determining Tea Quality

Evaluating tea quality requires a careful assessment of its appearance, aroma, and taste. Although many smaller details contribute to the evaluation process, the following guidelines cover the basics for all teas.

Good Tea Quality

Tea experts generally evaluate the appearance, aroma, and taste of both dry and wet tea leaves. Let’s begin by separating these two categories.

Dry Tea Leaves

Color: Green tea should display a dark green or emerald color. Oolong tea often takes striped or granular forms and has a bright orange color. Black tea comes in flaked or striped forms. Flaked black tea typically has a dark brown color, while striped black tea features tightly rolled leaves with a bright red appearance.

Shape: The shape of the tea leaves can also indicate quality. High-quality leaves should maintain a consistent shape and size, with tightly rolled or well-formed leaves.

Smell: Premium green tea should produce a fresh aroma with hints of orchid incense, chestnut, or other pleasant scents. Oolong tea may feature notes of ripe peach and floral fragrances. Aging or mold-like odors can indicate poor quality or deterioration.

Taste: When tasting the tea, consider the balance of flavors. A well-balanced product should contain the right proportions of bitterness, astringency, sweetness, saltiness, sourness, or other flavors associated with that type of tea.

Wet Tea Leaves

Aroma: Smell the tea after brewing to assess its aroma. High-quality tea should retain a pure and pleasant fragrance.

Color: Observe the color of the brewed tea. It should match the expected color for that type, such as bright olivine for green tea, bright orange for oolong tea, or bright red for black tea.

Flavor: Taste the brewed tea and evaluate its flavor. Quality tea should deliver a flavorful and well-balanced profile.

Residue: Examine the tea residue in the cup or pot. High-quality tea should leave minimal residue, which indicates that the leaves have fully infused into the water.

Bad Quality Tea

Bad-quality tea has few redeeming qualities. A moldy or stale smell often signals poor quality. Tea should produce some type of natural fragrance from its growing environment, so a missing aroma can also indicate a problem.

Excessively strong scents may suggest that the producer added fragrances to enhance the tea’s aroma. Many tea drinkers consider this practice unnatural and do not recommend consuming such products.

Fake labeling presents another concern. Although counterfeit products can prove difficult to identify, many producers create imitations of high-end teas. This practice appears particularly often in the pu-erh tea market with Red Seal and Yellow Seal varieties.

Bland flavor also indicates poor quality. As with any food or drink, some teas lack character. A decent tea should have a distinctive taste or noticeable freshness.
