protip_icon Fun Fact
Traditionally, Earl Grey tea was made with black teas like Chinese Keemun and served without milk. However, now it’s made with stronger tea varieties that can be flavored with milk or cream.

The tea leaves are usually infused with the signature citrusy scent towards the end of the manufacturing process. Let’s understand how it is made.

How Earl Grey Tea Is Made

Earl Grey tea is made by infusing black tea leaves with the natural oil extracted from the bergamot oranges’ rind. This combination yields Earl Grey’s signature refreshing and zesty flavor, setting it apart from other teas.

The process begins with plucking the tea leaves for withering to reduce moisture content. Then, the leaves are rolled and oxidized to achieve the desired flavor profile, followed by adding the bergamot oil. Then, the tea is dried to remove any remaining moisture, making the tea ready for brewing.

Apart from its uniquely delicious flavor, Earl Grey tea is becoming increasingly popular among consumers for providing innumerable health benefits. Scroll down to see what they are.

What Are The Benefits Of Earl Grey Tea?

1. May Boost Teeth Health

Some believe that the catechinsi  XChemical compounds abundant in tea, coffee, and chocolate that possess antioxidant and antimicrobial properties in the form of beverages. in Earl Grey tea (or any tea for that matter) can benefit the health of your teeth. Though direct research on Earl Grey tea is lacking, studies do show that tea catechins, in general, can promote oral health. Tea extracts were found to be helpful in preventing dental cariesi  XPermanently damaged areas in the teeth that lead to tiny openings or holes caused by bacteria or unhealthy oral hygiene. (1). More importantly, the fluoride in Earl Grey may also help prevent cavities and tooth decay.

Though more research is warranted, this is an encouraging step.

2. Eases Depression Symptoms

The bergamot oil the tea contains is known to have a calming effect on individuals. This can boost the person’s mood and help relieve symptoms of depression and anxiety and even provide stress relief (2). Bergamot’s natural aromatherapic qualities play a role here.

3. Can Boost Heart Health

This can again be attributed to the bergamot in the tea. As per studies, this key ingredient can lower cholesterol and prevent heart disease as a consequence. Bergamot contains essential enzymes like HMGF (Hydroxy methyl glutaryl flavonones) that can attack those proteins in the body known to cause heart disease (3). In fact, bergamot is considered as good as statins (a group of drugs prescribed for fat reduction) in improving heart health.

Studies also show that taking Earl Grey tea can even improve good cholesterol levels, which is another precursor for heart health.

4. May Enhance Digestion

Thanks to its anti-inflammatory properties, Earl Grey tea can ease abdominal issues like cramping, constipation, and hemorrhoids. Traditionally, this tea has also been used to treat colici  XProlonged and frequent intense fussing and crying in a well-fed, healthy baby due to distress or for no immediately obvious reason. and nausea.

Earl Grey tea also contains antioxidants, called theaflavins, which eliminate free radicals that can cause indigestion and other digestive issues. Research shows that consuming at least three cups of Earl Grey tea a week can cut the risk of digestive system cancer. Some believe that consuming at least three cups of Earl Grey tea a week can cut the risk of digestive system cancer, though more research is warranted here.

5. May Decrease Cancer Risk

The antioxidants in the tea can fight free radicals, which can otherwise lead to cancer in the long run. There are some interesting findings about ovarian cancer as well – women taking flavonoids, the antioxidants abundant in Earl Grey tea (and other teas as well), were found to be at a lower risk of developing ovarian cancer (4).

It also is beliebved that Earl Grey tea may have the potential to halt angiogenesis, which is a bodily process through which new blood vessels are formed. Angiogenesis    only happens in certain instances – for women during their monthly periods and pregnancy, and also for everyone when there is a physical injury. But once the need for these additional blood vessels is met, the body has to prune them back. The failure of this, due to any reason, can lead to diseases, cancer being one of them. However, whether Earl Grey tea contributes in this regard is yet to be studied.

6. Earl Grey Tea Fights Inflammation

This could be attributed to bergamot oil, again. Studies have demonstrated the amazing anti-inflammatory properties of bergamot oil (5). Since Earl Grey tea contains bergamot oil, it is hypothized that it also may help fight inflammation.

7. Might Promote Weight Loss

The bergamot in Earl Grey tea has citrus extracts that are known to boost metabolism, and they help you lose weight as a consequence. And there is caffeine in the tea, which also boosts fat burning and contributes to healthy weight loss. However, there is no research to support this. Evidence that exists is only anecdotal.

8. Boosts Immunity

The antioxidants in the bergamot oil fight free radicals and boost the immune system. They also fight oxidative stress, which can hamper the functioning of the immune system. Some research shows that bergamot may act as a bactericidal and antiviral agent, thereby boosting the immune system (6). This tea could be the ideal drink if you are suffering from symptoms of cold and fever. The tea may also treat a sore throat.

9. Might Treat Sunburns

Though there is very less research on this, some anecdotal evidence suggests that the antioxidants in Earl Grey tea can help heal sunburns. You just have to massage the tea over the affected area every morning and night.

These are the different ways you can use Earl Grey tea for your benefit. But how do you make the tea? What do you need?

How To Make Earl Grey Tea

The process is simple. You just need a couple of teaspoons of Earl Grey tea and some water. Here are the steps:

  1. Heat the water. Allow it to boil.
  2. Add a couple of teaspoons of the tea leaves to a cup.
  3. Pour the boiled water into the cup and let them steep.
  4. Strain the liquid and enjoy.

If you want to make the tea with milk, simply replace the water with milk. And if you want to have Earl Grey green tea, you can mix the leaves of both the teas and follow the process discussed above.

Nicole Jolly, a YouTuber, shares how she makes a perfect cup of Earl Grey tea with one special tip. She says, “First thing you want to do is to warm your vessel, which simply means your mug or your teapot, whatever you’re using. Because think about it – when you want to start brewing that tea, put the hot water on the tea, you don’t want the mug to absorb all of that heat away (i).”

For iced Earl Grey tea, simply let the leaves steep in the hot water. Strain the liquid and allow the tea to cool down. You can add a couple of ice cubes to it and have your iced tea.

Alternatively, you can prepare a cold Earl Grey brew, and add ice, mint, crushed ginger, or crushed fruits to add extra flavor.

Quite simple, isn’t it? Does this mean you can take the tea as many times as you want every day? Maybe not.

  • Issues During Pregnancy And Breastfeeding

Like most other teas, Earl Grey tea contains caffeine. This may not be safe for pregnant or breastfeeding women.

Excess caffeine can lead to anxiety, tremors, heart palpitations, and even sleeplessness(9), (10). If you have issues with caffeine intake, reduce intake of the tea.

  • Stained Teeth

You can rinse your mouth after drinking to prevent this.Individuals who have undergone tooth whitening procedures are also advised to avoid tea to prevent staining (11).

  • Issues With Iron Absorption

The tannic and gallic acids in the tea can interfere with the absorption of iron from leafy green veggies. Hence, reduce intake of the tea if you are deficient in iron. Also, drink the tea in between meals and not with them(12).

  • Bergamot Toxicity

Excess intake of the tea can lead to bergamot toxicity, which can interfere with potassium absorption (13). Anecdotal evidence suggests that other symptoms of bergamot toxicity may include cramps in the hands and legs, burning sensations, muscle twitches, and even blurry vision.
