5 Reasons Why Your Black Tea Tastes Bitter (and How to Fix It)
Last updated: August 2026
Black tea isn't naturally bitter. Bitterness comes from steeping too long, water that's too hot, stale leaves, the wrong amount of tea, or a dirty teapot. Fix the brewing and the bitterness goes away. Here are the 5 most common causes and how to fix each one.
Ready to try tea with no bitterness?
Every tea we sell is grown at 5,000 to 7,000 ft in the Himalayan highlands of Ilam and Taplejung, Nepal, where altitude, cool air, and slow growth produce leaves with no bitterness at all.
The best place to start is our Tea Sampler Kit: 10 loose leaf teas covering every style we carry, for $30 CAD. If your tea has ever tasted bitter, try these side by side.

1. Steeping too long
The longer black tea steeps, the more tannin it releases, and too much tannin makes it bitter. Most black teas need 3 to 5 minutes. Much longer than that and you get a strong, bitter, astringent cup. Set a timer and take the leaves out when it goes off. If you want stronger tea, add more leaf instead of steeping longer.
2. Using boiling water
Not every black tea wants boiling water, and some do better with something gentler. Delicate, light black teas such as Nepal Gold prefer water at around 195°F. Hotter water can scorch their subtler notes and leave the cup harsh or flat. A thermometer helps you hit the right temperature.
3. Stale or low-grade leaves
Stale or poor-quality leaves make a flat, lifeless cup. Black tea loses its flavour quickly if it's left open to air, light, or humidity. Keep it in a sealed container away from water, moisture, and sunlight. If your tea has lost its aroma or taste, it's time to buy fresh tea from a reputable supplier.
4. The wrong amount of tea
Too little tea gives a weak, bland cup, and too much makes it bitter and overpowering. A good starting point is about 1 teaspoon of loose leaf per 8 ounces of water. Adjust from there until you find the balance you like, and remember that weak tea is easier to fix than tea that's too strong.
5. The wrong teapot or cup
What you brew in affects the taste. Porous materials like unglazed clay absorb flavour and change the taste of your tea over time. If your tea tastes odd, try a glass or ceramic teapot. Make sure your teaware is clean, too, since leftover residue from earlier brews can spoil a fresh cup.
Bonus tip: rinse the leaves
For some teas, like pu-erh and heavily oxidized teas, a quick rinse with hot water first can wash away impurities and reduce bitterness. Pour boiling water over the leaves, swirl for a few seconds, and pour it away. Then brew as usual.
Fixing a cup that's already bitter
If your tea tastes too bitter, a dash of milk or a slice of lemon will usually help. If it's too weak, steep it a little longer or use more leaf next time. Small adjustments like these can turn a disappointing cup around.
Experiment with these details and you'll find your ideal brew. Brewing black tea well takes some practice, but each cup teaches you something, and with a little patience anyone can get very good at it.
