Even tea from the same shipment, tea garden and processing batch can differ in taste. Tea cupping is an ideal way to ensure quality control and consistent taste.
In addition, for many tea drinkers, the knowledge that a tea supplier properly cups its tea adds to the tea drinking experience.
Tea Cupping Steps – Black Tea Example
The term cupping is used to describe the examination and tasting of different teas to determine quality, taste, aroma, briskness, body and color. Cupping similar teas and comparing them against each other enables one to determine best value when making a purchase.
Before the tea is tasted however, a physical inspection of the leaves is performed and attention to the bouquet of the sample is also part of the process. In essence, proper cupping is based on an understanding of the total presentation of the tea leaf.
Appearance and Smell of the Dried Leaf
First, examine the dried leaf. Black tea for example, should be dark (blackish-brown) and well twisted, which indicates good withering.
An open, flat leaf infuses quickly; a closely twisted leaf takes longer to infuse and will give a better second cup. In general, the leaf should be small, hard, well rolled, and uniform in appearance.
The dry leaves can be squeezed to test the resilience of the leaf, which is an indication of young tea. This method of judging the quality of tea is only used for black teas. The appearance and smell of the dried leaf are not determining factors of quality in green and oolong teas.
Following the preliminary tea cupping steps, the tea is ready for the tasting part of the process. Generally speaking, the same care involved with the examination of the unsteeped tea leaves must be maintained during the steeping process.
Pure Water is Required
Purified, oxygenated water is best when preparing tea for tasting. Use water that has all minerals and other contaminants removed and oxygen added to ensure a fresh clean taste.
Remove contaminants because even fresh, clean water contains minerals that affect the taste of tea. Fill a kettle with water and bring to a boil.
Use the Proper Amount of Tea
Tea is measured per cup by weight not volume. Depending on the size of the tea and the extent of processing, teas of equal weight may vary in volume. To prepare for tea cupping, pour two grams into a six to eight ounce cup and pour the fresh boiling water directly onto the leaves.
Observe Steeping Time Limits – Don’t Over Steep
The steeping process, which releases the flavor from the tea leaves, has a certain time limit. After five minutes of steeping, the acids in the leaf begin to steep into the cup creating a bitter taste.
When tea cupping, begin by examining a weak infusion of tea. If black or oolong tea has not been fermented long enough, the infusion will be conspicuously bright in color and the leaf will have a green tint. Here are indicators based on the color or tint of the liquor:
The lighter the liquor, the younger the leaf is and the better the brew will taste. Smell the weak infusion to get some indication of the character of the tea and to detect possible burning during firing.
Please note that some teas require a longer steeping time (seven minutes for Oolongs) and some teas require a shorter steeping time (three to four minutes for green teas and Darjeelings). At the end of the prescribed time, pour off the tea from the leaves to halt the steeping.
Specific Requirements for Different Types of Tea
As with any rule, there are exceptions. The instructions listed above will be used for nearly every black tea you taste. However, some teas require a different process to bring out the true flavor of the leaf.
Green and White Teas: Green and white teas do not require you to fully boil the water. Pour the water from the kettle just before the water comes to a rolling boil (175° to 185° F). Also these teas usually take less time to steep. Three to four minutes is sufficient.
Oolong Teas: Finer oolongs have a very large, unbroken leaf. As a result, they usually need more time in the hot water to fully release the flavonols or catechins, which give the tea its flavor.
These suggestions for tea cupping are broad guidelines. No one method is considered the only way to taste and cup teas. Experiment, with other types of teas with different amounts and different steeping times.
The most important part of tea cupping is consistency. If there is one thing that is certain, it is that teas will change flavor when you change the brewing method and times.
Flavor Characteristics of the Drinking Infusion
The final step in tea cupping is to taste the flavor of the tea infusion, and described it in one of three ways. The first is the briskness, the second is the body, and the third is the aroma.
