Green Tea vs. Oolong Tea: What’s Really The Difference?

If you’re an avid tea drinker, you’ve probably sampled oolong tea and green tea at some point in your lifetime. You’ve probably also been informed of the amazing health benefits of green tea, but did you know that oolong has some healthy secrets, too?

Oolong and green tea are two of the most commonly consumed teas around the world, aside from black tea. However, it’s not always clear what sets them apart.

Oolong to Learn More!

Here’s the technical lowdown.

Oolong tea and green tea are both made from the same plant. In fact, here’s something you may not know: all teas come from the same plant. It’s called the camellia sinensis plant.

Both teas contain roughly the same amount of caffeine, and both originate from regions such as China, Japan, and Taiwan. However, they are widely available around the world.

There are some surface differences: green tea is- obviously – green, and oolong tea is often light brown. Oolong generally has a stronger flavour than green tea, and comes in a variety of tastes – from woody types to florals.

It’s All About The Process

The real difference between oolong and green tea is in how they’re processed.

Oolong tea is partially fermented, while green tea is unfermented. Partially fermenting the oolong tea means that it is partially oxidized, which is why it’s not quite the dark brown colour of black tea, which is fully oxidized. Green tea isn’t oxidized at all.

Oxidation refers to the process through which tea leaves are exposed to oxygen, resulting in a chemical reaction that causes browning. In turn, this causes the leaves to dry. As a result, the taste becomes quite different for oolong tea, giving it that unique flavour you know and love.

But Which One is Healthier?

Both oolong and green tea offer significant health benefits that make them both excellent choices.

While all tea contains catechins, green tea contains more of them than oolong. As a result, green tea tends to contain more antioxidants, which help burn fat and stimulate the mind. It also contains a significant amount of bioactive ingredients, which are great for overall health and maintenance, as well as building up walls in your body that protect against the formation of free radicals.

The health benefits of green tea are undeniable. However, in return, oolong tea has many things that green tea doesn’t offer.

Oolong tea is known to boost bone health, decrease inflammation, improve gut function, and help fight obesity. Some studies have shown that it has some boosting effects on one’s metabolism. Additionally, drinking at least one cup per day has been linked to reduced symptoms of eczema.

The Verdict

Our conclusion: you can’t go wrong with either tea, so why bother choosing?

Both teas contain enough antioxidants to give your body a boost, as well as improve your oral hygiene. Having a healthy mouth is more important than you realize – your mouth is connected to a variety of other issues.

Additionally, both teas taste great and blend well with so many other ingredients, providing you with a variety of ways to enjoy your tea. Whether you like it hot or cold, there are enough ways to fuel your body just by drinking your favourite cup.
