How Much Loose Leaf Tea Per Cup: The Perfect Ratio Guide From One Cup to a Full Pot

In the world of tea brewing, “precision” often brings the most stable and delicious drinking experience. For loose leaf tea, whether it is black tea, green tea, oolong tea, white tea or herbal tea, it is inseparable from the scientific tea-to-water ratio. Using the correct temperature for brewing different types of tea is also crucial for achieving the best flavor.

• The general “golden ratio” is 1 teaspoon (≈2 grams) of loose leaf tea per 240 ml (8 oz) of water, the benchmark for Western brewing.
• Tea bag equivalent: 1 tea bag ≈ 1 teaspoon (1–2 g) loose leaf tea.
• Traditional teacup and modern mug: Traditional: 6 oz (180 ml) → 1 teaspoon; Modern: 8 oz (240 ml) → 1 teaspoon; Large mug (12 oz) → 1.5 teaspoons.
• Teapot and tea kettle: 32 oz (4 cups) → 4 teaspoons; 64 oz (8 cups/2 quarts) → 8 teaspoons.
• ISO 3103: The professional sensory evaluation standard is 100 ml of water with 2 g of tea leaves, which is twice the concentration of the home brewing method.

Introduction to Loose Leaf Tea

Loose leaf tea is a type of tea that allows the leaves to expand and unfurl, releasing their natural flavors and oils. This type of tea is considered to be of higher quality than tea bags, as it provides a more nuanced and complex flavor profile. When brewing loose leaf tea, it’s essential to use the right amount of tea leaves and water temperature to bring out the perfect cup. The tea industry has created guidelines to help tea enthusiasts measure loose leaf tea, including the general rule of using one teaspoon of loose leaf tea per 8 oz cup of hot water. By following this rule, you can ensure that your tea is neither too weak nor too strong, allowing you to enjoy the full depth of flavor that loose leaf tea has to offer.

Why is the amount of tea so important?

Effects of insufficient and excessive dosage

• Insufficient dosage will make the tea soup as bland as “scented water”, and you will not be able to fully experience the plant fragrance and sweetness of the tea leaves;
• Excessive dosage, or using more tea leaves than necessary, will cause over-extraction of tannins and tea polyphenols, resulting in bitterness and astringency, covering up the delicate layers of the tea leaves themselves.

Repeatable tea brewing experience

With a consistent tea-to-water ratio, you can:

1. Maintain comparable taste across teas;
2. Control caffeine intake;
3. Achieve a great cup of tea every time by ensuring consistent, high-quality brewing.

Choosing the Right Tea Leaves

Choosing the right tea leaves is key to brewing the perfect cup of loose leaf tea. With so many types of tea out there - green tea, black tea, oolong tea, herbal tea - it can be daunting to decide which one to choose. But by understanding the characteristics of each type of tea - flavour profile, caffeine content, brewing requirements - tea lovers can choose the right tea leaves for their taste buds. For example green tea is light and refreshing, black tea is robust and full bodied. Loose leaf tea - tea bags and loose tea - comes in many forms - whole leaves, broken leaves, tea dust. Each form has its own brewing characteristics so choose the one that suits your tea experience.

The "golden ratio" of Western tea brewing

1 teaspoon/8 oz: a universal benchmark

Many tea industry and tea culture websites unanimously recommend: 1 tsp (≈2 g) loose leaf tea corresponds to 240 ml (8 oz) of water, which is the perfect amount for most black teas, green teas, oolong teas, and white teas.

Fine-tune strength

• Stronger: Increase to 1.5 teaspoons per 8 oz for a stronger brew, especially for stronger teas or iced teas.
• Lighter: Reduce to ¾ teaspoon for premium green or white teas to preserve their aroma and sweetness.

Replace tea bags with loose leaves in equal amounts

1 bag = 1 teaspoon

A standard commercial tea bag usually contains 1–2 g of tea leaves, which is similar to 1 level teaspoon of loose leaf tea. Many high-quality tea bags are filled with whole leaf tea, providing a loose leaf experience while maintaining the convenience of a tea bag.

Substitution tips: If you need 2 tea bags, you can replace it with 2 teaspoons of loose leaf tea

Adjust the amount of tea by cup size

6 oz Traditional Tea Cup

The traditional tea cup is typically 6 oz, which is smaller than the modern mug. When brewing loose leaf tea in a traditional tea cup, it’s essential to adjust the amount of tea leaves accordingly. A good rule of thumb is to use about 0.75 teaspoons of loose leaf tea per 6 oz cup of hot water. This will allow for the perfect balance of flavor and strength, and it will also prevent the tea from becoming too bitter or overpowering. Tea bags can also be used in traditional tea cups, but it’s essential to choose a tea bag that is designed for smaller cups to ensure the perfect flavor. By carefully measuring your tea leaves and adjusting for the smaller cup size, you can enjoy a perfectly brewed cup of tea every time.

8 oz modern mug

• 1 tsp
• 12 oz cup: 1.5 tsp
• 16 oz large mug: 2 tsp

When adjusting the amount for brewing hot tea, please double or reduce it proportionally, keeping 2 g/240 ml.

Specific dosage by tea type

Tea Type	Recommended dosage	Temperature and time
dark tea	1 tsp/8 oz; 1.5 tsp for thickening	212 °F (100 °C)，3–5 min
green tea	1 tsp/6–8 oz	175–185 °F，1–3 min
oolong tea	1 tsp/6–8 oz	195 °F，2–3 min
white tea	1 tsp/6 oz; 2 tsp peony buds	175–185 °F，2–5 min
herbal tea	1–2 tsp/8 oz	212 °F，5–7 min

When brewing different types of tea, it is essential to use the correct temperature to achieve the best flavor.

Teapot and large capacity tea brewing

32 oz (4 cups)

• 4 tsp (≈8 g) tea leaves

• Western brewing method: 1 tsp/8 oz, 3–5 min steeping time for tea;
• ISO 3103: 2 g/100 ml, 6 min steeping time, 90–95°C, for sensory evaluation
