What Is a Tea Infuser?

A tea infuser is a container or basket that holds loose leaf tea while it steeps, allowing water to circulate through the leaves while keeping them contained. When steeping is complete, you simply remove the infuser, leaving clean, leaf-free tea.

Key functions:

• Holds tea leaves during steeping

• Allows water to flow through leaves

• Keeps leaves contained

• Easy to remove when done

• Prevents leaves from floating in your tea

What Makes a Good Tea Infuser?

Size Matters

Large enough:

• Allows leaves to expand fully

• Better flavor extraction

• More room for proper steeping

Too small:

• Restricts leaf expansion

• Poor flavor extraction

• Can't hold enough tea

Rule of thumb: Choose an infuser that's at least 1.5-2 times the volume of your tea leaves.

Mesh Quality

Fine mesh:

• Prevents small particles from escaping

• Cleaner tea

• Better filtration

Too fine:

• May restrict water flow

• Slower extraction

Too coarse:

• Particles escape into tea

• Less clean tea

Ideal: Fine enough to catch particles, open enough for good water flow.

• Large opening

• Easy to access

• Simple to load

Easy to remove:

• Handle or chain

• Doesn't get stuck

• Cool to touch

Easy to clean:

• Opens for cleaning

• No hard-to-reach areas

Material Quality

Stainless steel:

• Long-lasting

Silicone:
