Oolong tea is one of the most historically rich teas in the world, often hailed for its health benefits. Originating in China, oolong tea has gained international recognition, not just for its taste but also for its potential impact on weight loss, caffeine levels, and more.
In this guide, we’ll explore everything from “is oolong tea green tea?” to its loose leaf options, how it compares to coffee, and even how it pairs with milk.
What Is Oolong Tea?
Oolong tea is a traditional Chinese tea that falls between green tea and black tea in terms of oxidation. It’s partially oxidized, giving it a combination of floral and roasted notes that tea lovers adore.
Why Oolong Is Unique
Oxidation level: 10% to 80%
Flavor: ranges from floral and fruity to roasted and nutty
Form: usually sold as rolled or twisted loose leaf tea
Color: golden yellow to amber
No two oolongs taste exactly the same.
Oolong vs Green Tea: The Truth
Many people ask: “Is oolong tea green tea?” The short answer is no, but they share similarities.
Aspect Green Tea Oolong Tea
Oxidation 0–10% 10–80%
Flavor Fresh, grassy Floral, toasty, nutty
Caffeine Lower Moderate
Processing Minimally processed Partially oxidized and rolled
So, while oolong may contain green tea-like freshness, it is its own category entirely.
Think of oolong as the perfect middle ground between green and black tea.
Oolong Tea and Weight Loss: Myth or Reality?
One of the biggest reasons people explore oolong tea is for its weight loss benefits.
Mechanism Behind the Claims
Boosts Metabolism: Oolong has been shown to increase energy expenditure.
Fat Oxidation: Encourages the body to burn fat more efficiently.
Blood Sugar Regulation: Helps maintain balanced glucose levels.
Reduces Cravings: May curb appetite when consumed before meals.
Multiple studies link oolong tea with reduced body fat and improved metabolism.
Which Has More Caffeine?
Another popular question: How does oolong tea caffeine compare to coffee?
Beverage Caffeine (per 8 oz)
Oolong Tea 30–50 mg
Green Tea 20–30 mg
Black Tea 40–70 mg
Coffee 80–120 mg
So while oolong tea has more caffeine than green tea, it has significantly less caffeine than coffee, making it a great alternative for people wanting:
Milder energy boost
Fewer jitters
Less acidity
A gentler impact on sleep patterns
If you’re reducing your caffeine intake, switching from coffee to oolong is a smart move.
Why Loose Leaf Is Better
Oolong loose leaf tea is the traditional choice among tea connoisseurs.
Benefits of Loose Leaf Oolong
Higher quality leaves: Whole leaves preserve aroma and oils.
Better flavor extraction: Leaves fully unfurl during steeping.
More re-steeps: You can brew oolong multiple times.
Loose leaf offers superior taste and health benefits.
Popular Oolong Tea Drinks
Beyond traditional brewing, oolong is now used in a variety of drinks and recipes, including:
Oolong Milk Tea: Common in bubble tea shops
Iced Oolong Tea: Refreshing and light
Oolong Latte: Creamy and smooth
Cold Brew Oolong: Subtle and floral
Oolong tea is more versatile than ever.
Should You Add Milk to Oolong?
Oolong tea and milk can be a great combo, especially for darker roasted oolongs like:
Tie Guan Yin (Iron Goddess)
Wuyi Rock Oolong
Da Hong Pao
These bolder oolongs can stand up to the creaminess of milk.
However, light oolongs (like green-style oolong) are better enjoyed plain.
Try milk with roasted oolong, but skip it for floral ones.

The term China oolong tea refers to oolongs produced in Fujian, Guangdong, and Taiwan. Each region has its specialties:
Fujian: Tie Guan Yin, Da Hong Pao
Guangdong: Dan Cong (Phoenix Oolong)

These teas are exported around the world.
