One Infuser, Three Ways to Brew
Most tea gear forces you to choose: a basket for loose leaf, a whisk and bowl for matcha, a pitcher for cold brew. The Mosi Tea Infuser takes a different approach. It is built around a simple idea — one bottle, one lid, and a set of interchangeable sieves that you swap depending on what you are drinking. That means fewer gadgets on your shelf and more flexibility in your cup.
Below you will find how each sieve works, how to brew loose leaf, matcha, and cold brew step by step, and how to build a setup that matches the teas you actually drink.
Getting Started: Know Your Sieves
The system is modular, so the sieve you install determines the brewing style. Here is the short version:
- Standard sieve — for whole-leaf teas, herbals, and blends with larger pieces.
- Matcha Sieve — a fine screen that breaks up clumps so matcha disperses instead of floating.
- Cold Brew Sieve — a longer, wider filter that gives leaves room to steep slowly in cold water.
- Mini Sieve — a compact option for smaller cups, finer cuts, or a quick single serving.
- Silicone Sieve — a flexible alternative that is easy to rinse and swap between brews.
If you are starting from zero, a starter kit bundles the infuser with tea so you can test several styles before committing to a favorite. The Mug Infuser Starter Kit is a straightforward entry point, while the Brew Anything Starter Kit leans into versatility with multiple brewing options in one box.
Brewing Loose Leaf Tea Step by Step
Loose leaf is the easiest place to begin, and it rewards a little attention to detail.
1. Measure the leaf
Use roughly one teaspoon of leaf per cup of water, then adjust. Large, fluffy leaves such as a full-leaf oolong need more volume than a dense broken leaf. If you are weighing, start near 2–3 grams per 8 ounces and taste from there.
2. Set your temperature
Boiling water flattens delicate greens and some oolongs. As a rule: black and herbal teas handle water just off a boil, oolongs sit a little lower, and green and white teas prefer cooler water. If you do not own a variable kettle, let the kettle rest for a minute or two after it clicks off.
3. Steep and lift
Add the leaf to the sieve, pour, and give it time. A robust Earl Grey Tea is typically ready in three to five minutes, while a lighter green may need only two. When the flavor is where you want it, lift the sieve out — leaving leaves submerged keeps them getting stronger and eventually bitter.
4. Try a few blends
Once the mechanics feel natural, branch out. A citrus-forward oolong, a floral Limited Release: Hibiscus Oolong, or a spiced Masala Chai Tea all behave differently in the same infuser, which is exactly the point. Chai and other spice-heavy blends often benefit from a longer steep and a splash of milk.
Matcha and Cold Brew
Matcha
Matcha is powdered, not steeped, so the goal is suspension rather than filtration. Press the powder through the Matcha Sieve first to break up lumps, then add water and shake or whisk until the surface is evenly cloudy with no dry pockets. A flavored option like Vanilla Matcha Tea is forgiving for beginners because the vanilla rounds out any bitterness from over-whisking.
Cold brew
Cold brew trades speed for smoothness. Install the Cold Brew Sieve, add leaf, fill with cold water, and refrigerate. Most teas need several hours; taste at the four-hour mark and again later, then remove the sieve when the strength suits you. The result is lower in bitterness and often sweeter than the same tea brewed hot. For smaller batches or a single glass, the Mini Sieve does the same job in less space.
Cleaning, Swapping, and Building a Set
Rinse sieves under warm water as soon as you finish a brew — wet leaf left sitting is the main cause of lingering odors. A soft brush handles the fine matcha screen; the silicone version flexes for a quick clean between cups. Let all parts air dry fully before reassembling.
From there, you can shape a collection around how you drink. A Black Tea Starter Kit suits morning routines, an Herbal Tea Starter Kit covers caffeine-free evenings, and a Tea for Wellness Set works well as a gift. If you are buying for someone else, the Coffee to Tea Gift Set and Holiday Bliss Gift Set both pair hardware with tea, so nothing extra is needed to start brewing the same day.
Start with one sieve and one tea you already enjoy. Learn its timing, then add a second style. The infuser is designed to grow with that habit rather than lock you into a single way of drinking tea.
