Learn how to brew single-cup loose leaf tea in the 150ml PLUMP Pot, from leaf ratio to pour timing, with practical steps and common mistakes to avoid.

Quick answer

For the PLUMP Pot 150ml, use about 3–4 grams of loose leaf tea and 150ml of water heated to the temperature your tea requires. Steep briefly, then pour everything out so the leaves do not keep brewing.

Why a 150ml pot changes your brewing habits

Small pots concentrate flavor quickly. With only 150ml, the margin between a bright cup and a bitter one is narrow, so measuring both leaf and water matters more than it does in a large pot. The PLUMP Pot's cork lid also traps heat and aroma, which helps delicate teas but can push a strong tea too far if you walk away.

Because the pot is made of heat-resistant glass, you can watch the leaves open and the liquor color change. That visual feedback is useful, but it is not a timer—use it as a backup, not your only guide.

When this method is not the right fit

If you regularly brew for two or more people, a 150ml pot will require back-to-back steeping or a larger vessel. Likewise, teas that need a lot of room to expand—such as large rolled oolongs—may feel cramped, so use a lower leaf ratio and shorter steeps. The PLUMP Pot is also not intended for stovetop or open-flame heating; heat water separately and pour it in.

Step-by-step brewing with the PLUMP Pot 150ml

Preheat the pot: Fill the PLUMP Pot with hot water, let it sit for 30 seconds, then discard the water. This warms the glass so your brewing water does not cool too fast. Do not skip this in a cold kitchen; a cold pot can drop your water temperature by several degrees.
Measure 3–4g of loose leaf tea: Use a small scale for accuracy. For most teas, 3g per 150ml is a light starting point; 4g gives a stronger cup. Adjust after your first brew. Avoid heaping spoonfuls—leaf size varies, so weight is more reliable than volume.
Heat water to the right temperature: Bring water to a boil, then let it cool for the tea type: about 70–80°C for green tea, 85–95°C for oolong, and 95–100°C for black and herbal teas. Pour the water into the pot. Never microwave the pot with tea leaves inside; heat the water separately to avoid overheating.
Start your timer and watch the clock: Steep for 1–2 minutes for green tea, 2–3 minutes for oolong, and 3–4 minutes for black tea. Set a timer rather than relying on color alone. If you lose track, pour immediately—over-steeping is the most common cause of bitterness in small pots.
Pour out every drop: When time is up, pour all the tea into your cup. Do not leave any liquid sitting with the leaves, or the next sip will be harsh. A second steep is possible for many teas; add fresh hot water and steep for about half the original time.
Clean and dry promptly: Rinse the glass pot with warm water and a soft sponge—no abrasive cleansers. Remove the cork lid and let both parts air-dry fully before storing. Avoid sudden temperature changes, such as rinsing a hot pot with cold water, which can crack the glass.
