Cup strainer: a great alternative to the tea ball

There are many types of tea filters. The cup strainer is a practical single-serve infuser, somewhere between a tea ball and a kitchen sieve. Usually made from stainless steel, it comes in various diameters and is easy to use. Some models include a small drip tray to keep your surface clean.

What is a cup strainer?

A cup strainer is a type of tea filter that takes its name from its resemblance to a kitchen sieve. It works with a cup, a glass, or a small teapot, and is most commonly made from stainless steel.

The idea is simple: the stainless steel tea filter rests directly on the rim of your cup, with the base sitting in the water. Once in place, your loose-leaf tea can begin to infuse.

How to use a cup strainer

A stainless steel cup strainer is one of the easiest tea infusers to use. Follow these steps for a perfect brew:

Choose your loose-leaf tea;
Heat the right amount of water to the appropriate temperature;
Place the cup strainer on your cup, mug, glass, or teapot;
Add the desired amount of loose-leaf tea to the strainer;
Pour the heated water over the stainless steel strainer;
Allow the tea to infuse in the cup, glass, or teapot;
Remove the strainer and enjoy your cup of tea.

You can also use a cup strainer the way you would a tea ball: fill your cup or glass with hot water first, then lower the stainless steel infuser filled with loose-leaf tea directly into the water. Either way, always adjust the water temperature to suit the tea you're brewing.

Pouring boiling water straight from the kettle over your tea leaves risks scalding them, resulting in a cup that's almost as bitter as a robusta coffee.

What are the benefits of a cup strainer?

A cup strainer is a versatile kitchen accessory. Conical models fit most cups, glasses, and mugs. Like a kitchen sieve, they catch all the loose-leaf tea, leaving your brew clear and clean.

The size of a stainless steel filter generally allows even the largest tea leaves to unfurl freely, resulting in a good-quality infusion. You can also use it with a small teapot. No teapot to hand, or brewing just for yourself? A cup strainer is a solid choice.

How to choose a cup strainer

Start with the material. A stainless steel infuser is an excellent option: durable, easy to clean, and neutral in taste. You'll also find tea filters in porcelain or plastic, but we'd steer clear of plastic, even if the price is tempting. Next, consider the diameter and depth of the tea filter to make sure it fits your favourite cup.

Cup strainers come in different shapes: some resemble a spoon, others are more upright. A model with a long stainless steel handle is easier to handle, and a stainless steel tea strainer that comes with a drip tray means no tea drips on your table or desk.
