Green tea is made from the leaves of Camellia sinensis. Unlike black tea, the leaves are processed to prevent full oxidation, which helps retain their fresh character and naturally occurring compounds such as catechins. The taste, aroma and quality of green tea depend on factors including the tea variety, growing region, processing method, freshness and how it is brewed.
In this guide, we cover the main benefits of green tea, how to make it properly, the best time to drink it, green tea leaves vs powder, and what to look for when buying good-quality tea.
What Is Green Tea?
Green, black, white and oolong teas all come from the same plant, Camellia sinensis. The main difference is how the leaves are processed after harvesting.
Green tea is heated during processing to limit oxidation, followed by steps such as rolling and drying. Different tea-producing regions use different methods, which is one reason green teas can have very different flavours and aromas. (NCCIH)
Kangra is one of India's recognised tea-growing regions. Tea Board India places its tea gardens between 900 and 1,400 metres above sea level and describes Kangra green tea as having a delicate woody aroma. Kangra Tea also has registered Geographical Indication (GI) status. (Tea Board India; IP India)
What Are the Benefits of Green Tea?
Green tea contains naturally occurring polyphenols, including catechins such as EGCG, as well as caffeine. These compounds have been studied for possible effects on several aspects of health. Some research has found modest effects in certain areas, but many of the broader health claims made about green tea remain inconclusive. (NCCIH)
Catechins and polyphenols
Catechins are a type of polyphenol naturally found in tea leaves. The amount extracted into your cup depends on the tea and factors such as leaf size, water temperature and brewing time. (PubMed)
Green tea and cholesterol
Clinical research suggests that green tea can have a modest effect on total and LDL cholesterol. However, much of the research has examined green tea extracts or supplements rather than ordinary brewed tea. (NCCIH)
Does green tea help with weight loss?
This is one of the most common questions about green tea. Catechins and caffeine may have a modest effect on body weight, but green tea has not been shown to be an effective weight-loss treatment by itself. (NCCIH)
Unsweetened green tea is a low-calorie drink, but that is different from claiming that it directly burns body fat.
How to Make Green Tea
The easiest way to get a better cup of green tea is to pay attention to water temperature and brewing time. Using freshly boiled water for a long steep can make some green teas taste harsh or bitter.
A useful starting point is around 80–85°C with a steeping time of 2–3 minutes. These are not universal rules; different teas may require different temperatures and brewing times. Research has shown that brewing conditions can significantly affect both extraction and taste. (PubMed)
A simple loose-leaf method
Tea: about 2 grams, or roughly one teaspoon depending on the leaf size.
Water: 200–250 ml.
Temperature: start around 80–85°C.
Time: 2–3 minutes.
Step-by-step
- Warm your cup or teapot with hot water and discard the water.
- Add the green tea leaves.
- Pour in water that has cooled below a full boil.
- Steep for around 2–3 minutes.
- Strain the leaves and taste the tea before adding anything else.
If the tea is too bitter, try cooler water, a shorter steep or fewer leaves. If it is too weak, increase the steeping time gradually.
Why Does Green Tea Taste Bitter?
Bitterness can result when the tea is over-extracted. Water temperature, brewing time and the characteristics of the leaves all affect which compounds move into the infusion. (PubMed)
That is why a tea that tastes balanced after two minutes can become much sharper when left for several more minutes.
What Is the Best Time to Drink Green Tea?
There is no scientifically established single best time to drink green tea. For most people, the practical considerations are caffeine, meals and personal routine.
Morning
Green tea can be a useful morning drink for people who want caffeine with a lighter tea flavour. The actual caffeine content varies by tea, serving size and preparation. (FDA)
Mid-morning or afternoon
These are convenient times to drink green tea while keeping it far enough from bedtime for people who are sensitive to caffeine.
Evening
Because green tea contains caffeine, drinking it late in the day may affect sleep in some people. Research has found that caffeine can reduce sleep duration and efficiency and increase the time needed to fall asleep. (PubMed)
Can You Drink Green Tea After a Meal?
There is one nutritional point worth knowing about drinking tea with food.
Tea polyphenols can reduce the absorption of non-heme iron, which is the form of iron found mainly in plant foods. Controlled human research has shown that tea consumed with an iron-containing meal can reduce non-heme iron absorption. (NIH Office of Dietary Supplements; PubMed)
This is more relevant to people who rely heavily on plant sources of iron or already have concerns about iron intake.
If iron absorption is a concern, drinking tea between meals rather than with an iron-rich meal may reduce this effect. In one controlled study, drinking tea one hour after the meal substantially reduced the inhibitory effect compared with drinking it with the meal. (PubMed)
Green Tea Leaves vs Green Tea Powder
Green tea is sold in several forms, but loose leaves and powdered tea are not interchangeable.
Green tea leaves
Loose-leaf green tea allows the leaves to open as they steep. You can see the leaf, control the quantity and adjust the brewing time more easily.
For people interested in tea origin and processing, loose leaf also makes it easier to examine the physical character of the tea.
Green tea powder
Green tea powder is a broad category and should not automatically be treated as matcha.
Matcha is a specific powdered green tea traditionally made from specially cultivated and processed tea leaves known as tencha before they are ground into a fine powder. (JETRO)
So when buying powdered green tea, check the product description, origin and production method rather than assuming every green tea powder is matcha.
Loose Leaf Green Tea vs Tea Bags
Tea bags are convenient, while loose leaf gives you more control over the brewing process.
| Feature | Loose Leaf | Tea Bag |
|---|---|---|
| Convenience | Requires an infuser or teapot | Very convenient |
| Leaf visibility | Easy to examine | Usually limited |
| Portion control | Easy to adjust | Usually fixed |
| Brewing flexibility | High | Moderate |
Neither format automatically guarantees better quality. The tea's origin, processing, freshness, storage and brewing method all matter.
How to Choose Good Green Tea Leaves
There is no single tea that is objectively the “best green tea” for everyone. A better approach is to look at the information available about the tea and decide whether it matches the flavour and style you want.
Look at the leaves
With loose-leaf tea, examine the leaves before brewing. Clearly identifiable leaf material gives you more information than a packet dominated by very fine dust and fragments.
Appearance alone does not prove quality, but it is one useful thing to inspect.
Smell the dry tea
Fresh green tea should have a clean, recognisable aroma. Depending on the style, it may smell grassy, vegetal, floral, sweet, nutty or woody.
A stale or musty smell can be a useful warning sign that the tea has lost freshness.
Check the origin
Tea is an agricultural product, so growing region matters. Climate, terrain, soil, cultivar, season and processing can all influence the final flavour.
For Indian tea, identifying the region can tell you considerably more than a generic description such as “premium green tea.”
Look for harvest and packing information
Check the packaging for useful information such as packing details and a clear best-before date.
Freshness is particularly important when you want to experience the aroma and flavour of a less heavily processed tea.
Pay attention to packaging
Tea should be protected from moisture, excessive light, heat and strong surrounding aromas. A well-sealed package helps preserve freshness during storage.
How to Store Green Tea
Once opened, keep green tea in a cool, dry and dark place.
A properly sealed container is preferable to an open paper packet. Keep the tea away from strongly scented foods and spices that could transfer their aroma.
What Makes Kangra Green Tea Distinctive?
Kangra is a recognised tea-growing region in Himachal Pradesh with a documented history stretching back to the nineteenth century.
Tea Board India places Kangra's tea gardens between 900 and 1,400 metres above sea level and describes the area's tea as being influenced by its climate, terrain, soil conditions and the coolness of the surrounding mountains. Kangra green tea is described as having a delicate woody aroma. (Tea Board India)
Tea cultivation in Kangra dates to 1849, when Dr. Jameson, then superintendent of the Botanical Tea Gardens, identified the region as suitable for tea cultivation. Kangra Tea subsequently developed into a recognised regional tea and now has registered GI status. (Tea Board India; IP India)
The significance of Kangra tea is therefore not just its location. It has a documented growing tradition, a defined geographical identity and a character that Tea Board India specifically associates with the region.
Palum Dhara Kangra Green Tea
At Palum Dhara, we approach Kangra Green Tea as a regional food rather than simply another green tea on a shelf.
Our Kangra Green Tea — Single Estate • Whole Leaf is presented around the character of the leaf and its Himalayan origin.
The simplest way to prepare it is also the best place to start: fresh water, moderate heat and a short infusion. From there, adjust the brewing to suit the leaves and your taste.
