Tea FAQ: Your Ultimate Guide

Tea lovers ask us lots of great questions about brewing, storing, and enjoying tea. At Tea The World, we’ve gathered the most common ones here, from how long brewed tea lasts to choosing a kettle.

How Long Is Brewed Tea Good For?

• Room temperature: Best within a few hours, and no more than about 8 hours. Keep it covered.
• Refrigerated: Store brewed tea in a clean, airtight container for up to 2–3 days. Flavor is best within the first day.
• Tip: If tea smells sour, looks slimy, or has been left out overnight in a warm room, toss it.

How Should I Store Tea Leaves?

1. Airtight, opaque containers protect tea from air and light.
2. A cool, dark, dry place keeps leaves fresh. Avoid the area above the stove.
3. Keep teas separate so strong flavors don’t mingle.
4. Stay away from odors like spices and coffee, which tea absorbs easily.

Why Does Iced Tea Turn Cloudy?

• Rapid cooling: Compounds in tea, including tannins and caffeine, can bind together as hot tea is chilled quickly.
• Hard water: Minerals react with tea compounds.
• Over-brewing: Very strong tea is more likely to cloud.

To prevent it: Avoid over-steeping, let tea cool to room temperature before refrigerating, use filtered water, or try cold brewing, which usually stays clear. Cloudy tea is safe to drink; it’s a cosmetic issue.

What Water Should I Use?

1. Filtered water removes chlorine and off-flavors.
2. Fresh, cold water each time. Re-boiled water can taste flat.
3. Avoid distilled water, which makes tea taste dull. Very hard water can also flatten flavor and cause cloudiness.

What’s the Best Kettle for Tea?

• Temperature control: Lets you brew green, white, oolong, and black teas at their ideal temperatures.
• Gooseneck spout: Gives precise pouring.
• Durable materials: Stainless steel or glass.
• Keep-warm function: Handy for multiple steeps.

How Much Tea Should I Use?

A good starting point is 1 teaspoon (about 2 grams) of loose leaf tea per 8 oz cup. Use a little more for fluffy herbal teas. Adjust to taste.

How Long Should I Steep?

• Green: 2–3 minutes at 160–180°F
• Black: 3–5 minutes at 200–212°F
• Oolong: 3–5 minutes at 185–205°F
• Herbal: 5–7 minutes at 200–212°F

How Do I Store Specialty Teas?

• Matcha: Keep sealed in the refrigerator after opening and use within a month or two for the best color and flavor. Let it reach room temperature before opening to avoid condensation.
• Pu-erh: Can be aged; store in a breathable container away from strong odors.
• Oolong: Airtight containers in a cool, dark place.
