All true teas come from the Camellia sinensis plant. White tea, green tea, yellow tea, oolong tea, black tea, and pu-erh tea all come from this plant. This means that beverages made out of things like chamomile, mint, and lemongrass are not really teas, they are called tisanes — which is another word for an herbal or plant infusion.
You are probably wondering, if all of these teas come from the same plant, why are they so different? The differences between the types of tea rely on three main things — terroir, cultivar, and processing methods.
Terroir refers to how the geography, geology and climate of a place influence the appearance and taste of a tea. A good analogy for terroir can be seen in the wine world, as many wines are named after the region in which the grapes are cultivated, and they exhibit characteristics that are specific to that growing region. The same cultivar of C. sinensis can be grown in two different regions of China and produce entirely different tastes of tea.
Not all cultivars of C. sinensis are suitable for making a specific style of tea. A tea farmer will likely choose a specific varietal known for a desired characteristic to make a certain style of tea. For example, silver needle white tea, a tea made strictly from the buds of the tea plant, is often created from the Da Bai Hao cultivar of the plant which is known for producing large buds covered with white hairs.
While terroir and cultivar greatly influence the taste and appearance of a tea type, it is the processing method that truly defines a type of tea. While there are exceptions to the following definitions, I find it is important to understand how each type of tea is processed in its simplest form. For each style of tea, different leaves are used, and once the leaves are plucked, processing begins…ready for a lot of information?
All of these processes greatly influence the creation and destruction of different chemicals within the leaves and leave us with the beautiful colors and flavors of the different types of tea we find on the market today.
As everyone’s taste is a little bit different, there is no right or wrong way to steep tea. However, I’ll offer you my guide to coaxing what I think are the best flavors out of tea leaves. Tea should not be bitter; if you’ve ever had to add cream or sugar to tea or if you’ve been served a bitter brew, it was not properly prepared. In fact, one or both of these things most likely happened: the water was too hot, or the tea was steeped for too long. If you are preparing tea for yourself and your tea comes out bitter, reduce the temperature and/or the steep time. Experimentation is key when learning to steep a new tea.
For white, green and yellow teas, you’ll want to keep the water well under boiling. For whites, I recommend a steeping temperature between 150 and 160 degrees Fahrenheit, and for greens and yellows, between 170 and 180°F. Oolongs, black and pu-erh teas can handle higher temperatures; for oolong I recommend a steeping temperature between 190 and 195°F, black and pu-erh teas can be steeped at or just under boiling.
The steeping vessel is also another important consideration. The major concern here is leaf expansion; if the leaves do not have room to expand, you will lose flavor. There are heaps and heaps of gimmicky tea infusers on the market today, and most have very tiny spaces for the tea to infuse. Make sure your leaves can swim. You really don’t even need an infuser; the best way to infuse tea is to let the tea leaves float freely in the water, then strain them into another vessel once the steeping time has passed. Once strained, the leaves can be set aside for the next steeping. Speaking of next steeping, don’t forget to re-steep your tea. Using a series of short steeps is the best way to get the most out of your tea, and you’ll get to experience the tea as it develops from steeping to steeping. Also, be sure that your water source is a good one. If your water tastes bad, your tea will taste bad. Here is a chart of steep times and water temperatures that you can use as a basis for your experimentation:
|Tea||Water Temperature||1st Steep||2nd Steep||3rd Steep||4th Steep|
|White||150-160ºF||1 min||1 min||1.5 min||1.75 min|
|Green||170-180ºF||1 min||1 min||1.5 min||1.75 min|
|Yellow||170-180ºF||1 min||1 min||1.5 min||1.75 min|
|Oolong||190-195ºF||30 sec||30 sec||45 sec||45 sec|
|Black||212ºF||1 min||1 min||1.5 min||1.5 min|
|Pu-erh||212ºF||30 sec||30 sec||45 sec||1 min|
When steeping, use 3 grams (approximately 1 tsp) of tea for each 6 ounces (approximately 0.75 cups) of water. If you want to get serious about tea, look into getting yourself a Yixing pot, or a gaiwan for steeping. Finally, store your tea in a place free from heat, light, air, and odors and it should last several years.
When shopping for tea, look for companies that offer information about where the tea is from, how it was processed, who grew it, and most importantly, when the tea was harvested. Look for large, whole, uniform tea leaves free from broken pieces as you want the tea to steep uniformly. There are plenty of places out there for tea reviews— the best sites are Steepster and RateTea.com.
