Mastering the Art of Tea Steeping.

Indulging in a delightful mug of tea has the power to banish the wintry breeze, reenergize you throughout the day, or promote relaxation at night.

To prepare tea, one must immerse it in steaming hot water. Steeping involves the extraction of flavors and health-enhancing compounds from the solids used in tea production.

This article elucidates the optimal techniques for steeping tea, guaranteeing an impeccable cup each and every time.

Not all teas are created equal, and the methods of steeping vary depending on the type you wish to brew.

Genuine teas originate from the Camellia sinensis plant and encompass varieties such as black, green, oolong, and white tea. The taste, hue, and antioxidant content of these teas diverge based on the level of oxidation the leaves undergo prior to drying (1).

True teas can be procured in a dried format, either in loose leaf form or within tea bags.

Herbal teas, otherwise known as tisanes, do not belong to the realm of true teas. Instead, they constitute infusions or decoctions made from the roots, leaves, stems, or blossoms of various herbs and plants, such as hibiscus, peppermint, rooibos, chamomile, turmeric, or ginger.

While dried ingredients are commonly utilized, it is also possible to concoct herbal teas using fresh components.

The fundamental steeping technique remains the same for both types of tea, but the quantities required to brew a single cup may differ between dried and fresh ingredients. Additionally, the duration of steeping and the temperature of the water necessary to extract optimal flavors might also vary.

summaryTrue teas are derived from the Camellia sinensis plant, whereas herbal teas originate from diverse parts of other plants. The ideal steeping method differs for each type.

Commence with fresh ingredients If you opt to brew an herbal tea utilizing fresh materials, such as herbs or ginger or turmeric root, it is advisable to employ them promptly after cutting or purchasing.

Dried tea leaves possess a lengthy shelf life when stored in a cool, dry container that is airtight and shielded from direct sunlight. Nevertheless, extended storage periods may exert adverse effects on the quality, flavor, and aroma (1).

Genuine teas contain polyphenolic compounds with antioxidant properties, namely catechins, theaflavins, and thearubigins. These compounds are accountable for many of the health benefits associated with tea, but they tend to degrade over time (1, 2).

A group of researchers closely observed the levels of antioxidants present in green tea stored at a temperature of 68°F (20°C) and discovered that after a period of 6 months, the catechin levels decreased by 32% (source).

It is important to note that the quality of the water used significantly impacts the flavor of your tea. If your tap water has high mineral content or has been treated with chlorine, it may result in an unpleasant taste. For the best outcome, it is recommended to use fresh, cold, and filtered water when brewing your tea (source).

In order to steep your tea, you should pour hot water over the ingredients and allow them to rest for a few minutes. The ideal steeping time varies depending on personal preference, and it is advised to experiment until you find the flavor that suits you best. However, it should be noted that a hotter temperature or longer steeping time does not necessarily lead to a better taste. Studies have shown that green tea prepared with these conditions scored lower in terms of color, flavor, aroma, and overall acceptability (source).

Conversely, if the steeping time is too short, you will not be able to extract enough flavors and antioxidants. Researchers have analyzed the amount of polyphenol antioxidants extracted over time from black tea and found that it takes approximately 6-8 minutes to extract the maximum amount (source).

It is worth mentioning that the caffeine content increases with a longer steeping time. Different types of true teas have varying amounts of caffeine. A 6-ounce (178-ml) cup of black tea contains 35 mg of caffeine, while the same serving of green tea contains 21 mg (source 1, source 2).

Extending the steeping time by an extra minute can increase the caffeine content by up to 29%, and using boiling-temperature water can result in a caffeine increase of up to 66% (source).

If you prefer the hot steeping method, it is the quickest way to brew a delicious cup of tea. Below are some general guidelines for the optimal steep time and temperature for popular teas (source 1, source 2).

Generally, green tea requires more delicate treatment, while black and herbal teas are more forgiving when it comes to temperature and steeping time.

If you intend to enjoy your tea in an iced form, cold steeping may be a suitable option. Cold steeping in water at lower temperatures or room temperature yields a tea that is less bitter, more aromatic, and offers a higher antioxidant content.

However, it is important to note that the lower the steeping temperature, the longer the brewing process will take, often requiring up to 12 hours in most cases.

A study revealed that steeping tea at 40°F (4°C) for 12 hours is more effective in extracting and retaining polyphenols compared to steeping for 3–4 minutes in hot water.

Additionally, the same study discovered that steeping tea for 3–5 minutes at 175°F (80°C) and then adding ice produces a similar taste and antioxidant content as the 12-hour cold steeping method, providing a quicker alternative.

To extract antioxidants, caffeine, flavors, and aromas from tea, steeping in hot water typically takes around 5 minutes to brew a satisfying cup. On the other hand, cold steeping requires up to 12 hours and yields a smoother-tasting tea with higher levels of antioxidants.

When it comes to steeping tea, you can use special tools or keep it simple and still achieve expert results.

At the very least, you will need a teacup, tea bag, and kettle. Place the tea bag in your teacup and fill the kettle with fresh, cold, and filtered water. Bring the water to a boil, or slightly below boiling for green or white tea, before pouring it over the tea bag in the teacup. While optional, covering the teacup with a saucer can help retain more aromatic compounds. Allow the tea to steep for approximately 5 minutes, adjusting the steeping time according to your preference.

For loose leaf tea, you will also require a metal tea ball or infuser to hold the leaves. Measure 1 teaspoon of dried tea leaves or 1 tablespoon of fresh ingredients for every 6–8-ounce (177–237-ml) cup. Place the leaves in the tea ball or infuser and submerge it in a cup of hot water for the recommended steeping time.

Although steeping loose leaves involves a few more tools, it offers a wider variety of tea options compared to bagged tea, allowing for more flavor combinations and potential health benefits. Moreover, loose leaves can be re-infused, making it a more cost-effective long-term option. In fact, a study found that while bagged tea produced the best results for a single brew, the majority of loose leaf teas still maintained antioxidant activity after the sixth brew.

For cold-brewed tea, it is advisable to prepare multiple servings at once in a large mason jar due to the lengthy steeping time. Fill the jar with fresh, cold water and add 1 tea bag or 1 teaspoon of dried tea in an infuser for every 6 ounces (177 ml) of water.

The process of steeping tea in hot or cold water allows the distinct flavors, aromas, and beneficial compounds to be extracted from dried leaves or other ingredients, whether they are fresh or dried.

While there are recommendations for ideal steeping times and temperatures based on the type of tea, exploring and experimenting with your own steeping methods will enable you to find the flavor profile that suits your taste preferences.

If you are a tea enthusiast looking to expand your palate, loose leaf teas offer diverse flavors and potential health benefits, all while being more economical and environmentally friendly.
