How to Brew the Perfect Cup of Microground Tea

The thing that makes microground tea genuinely easy to brew is the same thing that takes a moment to wrap your head around: there's no steeping involved. You're not extracting flavour from a leaf and then removing it. You're mixing the whole leaf - already ground into a fine, highly dissolvable powder - directly into liquid. When the powder is evenly distributed and the liquid is the right temperature, you're done. No timers, no strainers, nothing to fish out of the mug.

That simplicity is real, but it doesn't mean every cup comes out the same. Water temperature has a significant effect on flavour, particularly for green tea-based powders. How you mix matters. The ratio of powder to liquid is something most beginners get slightly wrong in either direction before settling into what works for them. This guide covers all of it - one tea at a time, with the specific numbers that produce the best result.

The Tools Worth Having

You don't need specialised equipment to make a good cup of microground tea. But a few inexpensive items make a meaningful difference.

A small handheld milk frother is the single most useful tool for any microground tea. It disperses the powder more evenly and more quickly than a spoon, produces a slightly frothy texture that improves the mouthfeel, and costs under $15 at most kitchen stores. If you already have one for coffee, it works perfectly here.

A bamboo matcha whisk (chasen) is the traditional tool for Pure Matcha specifically, and it produces a beautifully frothy result with a smooth, even texture. It's worth having if you drink matcha regularly, though a frother is a reasonable substitute for everyday use.

A variable temperature kettle removes all guesswork from water temperature, which matters significantly for the green tea-based powders. If you don't have one, the practical workaround is simple: boil your water, then wait. A full boil drops to approximately 80°C after about five minutes with the lid open, or about three minutes if you pour it into a cold cup first. For the black tea and rooibos-based teas, you can pour directly from the boil.

A shaker bottle - the kind used for protein shakes - works extremely well for iced preparations and for anyone making tea on the go. Add powder, add liquid, shake hard for ten to fifteen seconds, pour. We covered this in our post on microground tea as the best portable drink for getaways, and the shaker method is genuinely the easiest way to make a great iced tea without any equipment.

The Paste Method: The One Technique That Makes Everything Better

Whether you're making matcha, chai, or any other microground tea, one technique consistently produces a smoother result than starting with a full cup of liquid: the paste method.

Add your powder to the mug first. Then add a small amount of your liquid - two to three tablespoons - and mix vigorously until the powder is fully incorporated into a smooth, lump-free paste. Only then add the rest of your liquid. The paste dissolves into the larger volume effortlessly, with no dry clumps sitting at the bottom of the mug.

Skipping this step and adding powder directly to a full cup works, particularly with a frother, but it's more likely to leave small pockets of dry powder that never fully integrate. The paste step takes fifteen extra seconds and removes that risk entirely.

Brewing Guide: Each Tea, Step by Step

Pure Matcha

Pure Matcha is where temperature matters most. Green tea powder is sensitive to heat - water above 85°C extracts more of the leaf's bitter compounds (catechins and caffeine) and dulls the vibrant green colour. The target range is 70 to 80°C, which is hot enough to mix smoothly and bring out the natural sweetness and umami of the leaf, without the harshness that boiling water produces.

Serving size: 1 teaspoon (approximately 2 grams). Start here and adjust - some people prefer a slightly stronger or lighter cup.

For a traditional matcha (just powder and water):

1. Heat water to 70-80°C - boil and wait 5 minutes with the lid open, or 3 minutes poured into a cold cup.

2. Add 1 tsp of matcha powder to your mug or bowl.

3. Add 2-3 tbsp of the warm water and whisk or froth into a smooth paste.

4. Add the remaining water (total of about 150-180ml for a standard cup).

5. Whisk in a quick W or zigzag motion until frothy. Drink immediately.

For a matcha latte:

1. Follow steps 1-3 above to make the paste.

2. Steam or warm your milk of choice separately - dairy, oat, and almond all work well.

3. Pour the warm milk over the matcha paste and stir or froth to combine.

4. The ratio is roughly 1 tsp matcha to 200-250ml milk for a latte-strength drink.

Quick temperature tip: If your matcha ever tastes bitter or flat, the water is almost certainly too hot. Let it cool longer before the next cup. If you're unsure, err cooler - 70°C produces a gentler, sweeter cup than 80°C.

Vanilla Matcha

Vanilla Matcha follows the same temperature rules as Pure Matcha - green tea base, 70-80°C, same paste method, same quantities. The vanilla addition means the final cup has a touch of natural sweetness that makes it slightly more forgiving if your temperature runs a little high, but the same principle applies: cooler water, smoother flavour.

Serving size: 1 to 1.5 teaspoons, depending on how pronounced you want the flavour. Vanilla Matcha works beautifully as a latte - the vanilla and tea notes pair particularly well with oat milk, and the combination is sweet enough that many people don't add any sweetener at all.

For an iced Vanilla Matcha latte, make the paste with a small amount of warm water (even 60°C is fine for the paste step), then pour over ice and top with cold milk. Shake or stir well.

Classic Chai

Black tea is the base of Classic Chai, and unlike green tea, black tea is designed for high heat. Full boiling temperature (100°C) is not only acceptable here - it's often preferable, as it brings out the depth of the black tea and the warmth of the spices more fully. There's no bitterness risk from water temperature with a black tea base the way there is with matcha.

Serving size: 1 tablespoon per 250ml of liquid. This ratio produces a full-bodied, properly spiced cup. Go to 2 teaspoons for a lighter version, or increase to 1.5 tablespoons for something closer to café-strength.

For a chai made with just water:

1. Boil your water.

2. Add 1 tbsp of chai powder to your mug.

3. Add 2-3 tbsp of boiling water and stir into a smooth paste.

4. Fill with the remaining boiling water (to about 250ml total).

5. Stir well and drink as-is, or add a splash of milk.

For a chai latte:

1. Make the paste with a small amount of boiling water (2-3 tbsp).

2. Heat your milk separately - steamed oat milk or dairy both produce a rich, creamy result.

3. Pour the warm milk over the paste and stir or froth. 250ml of milk to 1 tbsp of chai is the target ratio.

4. Sweeten with honey or maple syrup if desired, though the spices tend to read as sweet on their own.

We've written a full step-by-step guide in our post on how to make a chai latte at home in under two minutes if you want the extended version.

London Fog

London Fog is a black tea base with bergamot and vanilla, and like Classic Chai, it welcomes high water temperature - 90-100°C works well. The bergamot character opens up fully with heat, and the vanilla rounds it out into something that genuinely earns the "fog" name when made with steamed milk.

Serving size: 1 to 1.5 teaspoons per 200-250ml of liquid. London Fog is typically made as a latte - water alone works but the flavour is more linear; milk turns it into something considerably more interesting.

For a London Fog latte:

1. Add 1-1.5 tsp of London Fog powder to your mug.

2. Add 2-3 tbsp of hot water (90-100°C) and mix into a paste.

3. Steam your milk to a light froth - oat milk and whole dairy milk both produce a good texture.

4. Pour steamed milk over the paste, stir, and allow the froth to settle on top.

5. Add a small amount of vanilla syrup or honey if you want it sweeter, though the vanilla in the blend means many people don't find it necessary.

Rooibos Turmeric Chai

Rooibos Turmeric Chai is the caffeine-free option, and rooibos handles heat well - boiling or near-boiling water is perfectly appropriate and brings out the full warmth of the turmeric and spices.

Serving size: 1 tablespoon per 250ml of liquid, the same as Classic Chai. The flavour is somewhat less intense than the black tea-based chai without milk, so for a richer result, making it with milk or at least a splash of milk is recommended.

For a rooibos chai latte (the recommended approach):

1. Add 1 tbsp of Rooibos Turmeric Chai to your mug.

2. Add 2-3 tbsp of boiling water and mix into a paste.

3. Warm your milk separately - oat or coconut milk pairs particularly well with the earthy rooibos and turmeric notes.

4. Pour the warm milk over the paste and stir or froth. A small pinch of black pepper can improve turmeric absorption if you're thinking about it from a nutritional standpoint, though it's entirely optional.

Because it's caffeine-free, Rooibos Turmeric Chai is the most versatile tea in the lineup for time of day - morning, afternoon, or a genuinely satisfying evening cup without any sleep disruption.

Making Any OGB Tea Iced

Every microground tea in the lineup works cold, and the preparation is straightforward. The key is making a small warm paste first even for iced drinks - cold liquid alone makes mixing harder and increases the chance of clumps. A small amount of warm water (even room temperature is enough) to create the paste, then add cold liquid and ice.

Shaker method (easiest): Add powder to a shaker bottle. Add 3-4 tbsp of warm water and shake until a smooth paste forms. Add cold milk or water to your preferred volume, add ice, shake again hard for 10-15 seconds. Pour and drink immediately.

Layered glass method: Make the paste in the bottom of a glass with a small amount of warm liquid. Add ice to the glass. Pour cold milk slowly over the ice to create a layered effect. Stir before drinking. This works particularly well with Vanilla Matcha and London Fog, where the colour contrast is visually appealing.

Common Mistakes and How to Fix Them

Bitter matcha

Almost always caused by water that's too hot. Boiling water scalds the green tea leaf powder, extracting bitter compounds and dulling the colour. Let your water cool to 70-80°C before adding it to the paste. If your matcha tastes bitter, cooling the water down is the first thing to try.

Clumpy powder that won't mix

Either the liquid is too cold (for green tea powders especially), or you added the powder directly to a full cup of liquid rather than making a paste first. Try the paste method: mix the powder with a small amount of warm liquid until smooth before adding the rest. A frother also helps significantly here.

Flavour that's too weak

Increase the serving size slightly. Start with 25% more than the base recommendation and taste. For latte preparations, also check the milk ratio - if you're using significantly more than 250ml of milk per serving, the flavour will be diluted proportionally.

Flavour that's too strong or intense

Reduce the powder by a small amount, or increase the liquid volume. All five teas are adjustable in this way - there's no fixed rule, and the "right" ratio is the one that tastes right to you. Beginners tend to prefer a slightly lighter serving than what regular tea drinkers find satisfying.

Milk scorching or getting a skin

If you're heating milk on the stove, don't bring it to a full boil - steaming point (small bubbles just beginning to appear at the edges) is the right stage. Microwaving works well too; heat in 30-second intervals and stop when you see steam rising. Overheated milk loses its sweetness and develops an off-flavour that competes with the tea.

Powder clumping in storage

Microground tea powder is fine enough to absorb moisture from the air, which causes clumping over time. Our bags are designed to keep moisture and light out, but always reseal the zip-lock firmly after every use. Store in a cool, dry place away from steam (not directly above the kettle). If you notice any clumping, break it up before measuring - the flavour is unaffected.

Quick Reference: Temperature and Ratio by Tea

Pure Matcha: 70-80°C water, 1 tsp per 150-180ml (straight) or per 200-250ml (latte).

Vanilla Matcha: 70-80°C water, 1 to 1.5 tsp per 200-250ml (latte or straight).

Classic Chai: 90-100°C water, 1 tbsp per 250ml liquid.

London Fog: 90-100°C water, 1 to 1.5 tsp per 200-250ml (latte recommended).

Rooibos Turmeric Chai: 90-100°C water, 1 tbsp per 250ml liquid.

All teas: make a paste first with 2-3 tbsp of warm liquid before adding the full volume. Adjust to taste. All work hot, warm, or iced.

Frequently Asked Questions About Brewing Microground Tea

Do I need a bamboo whisk to make matcha?

No. A bamboo whisk (chasen) produces the most traditionally smooth and frothy matcha and is worth having if you drink Pure Matcha regularly, but a handheld milk frother is a fully functional substitute and easier to clean. A regular spoon works in a pinch, particularly if you use the paste method first, though the texture won't be quite as consistent.

Can I use boiling water for matcha?

It will work, but the result will be noticeably more bitter and the colour will be duller - boiling water extracts harsh compounds from green tea that cooler water leaves behind. For the best flavour from Pure Matcha or Vanilla Matcha, let boiled water cool to 70-80°C before using it. For the black tea-based teas (Chai and London Fog) and Rooibos Turmeric Chai, boiling water is perfectly appropriate.

What milk works best with these teas?

For matcha: oat milk is the most popular non-dairy choice - it's neutral in flavour and produces a creamy texture that suits the green tea well. Whole dairy milk also works beautifully. For chai and Rooibos Turmeric Chai: oat milk, coconut milk, and dairy all work well. Coconut milk adds a slightly sweet, tropical note that pairs nicely with the spices. For London Fog: oat milk or whole dairy are the best fits for the bergamot and vanilla character.

How do I make an iced version without it tasting watery?

Two things help: use the full serving size rather than reducing it for iced (the ice dilutes the flavour), and make the paste with warm rather than cold liquid before adding ice and cold liquid. If you're making a large iced drink, increase the powder slightly to compensate for the dilution from ice melting.

How much powder should I use if I'm new to microground tea?

Start at the lower end of the recommended range - 1 tsp for the matcha powders, and slightly under a tablespoon for the spiced blends. Taste the result and adjust from there. Most people settle into their preferred ratio within a few cups. There's no exact right answer - the recommended quantities are a well-calibrated starting point, not a fixed rule.

Can I make a concentrate to use throughout the week?

You can make a small paste ahead of time and refrigerate it for up to a day, though freshness does diminish. The better approach for convenience is simply to keep the sealed bag near your kettle - since preparation takes under two minutes, making it fresh each time is genuinely practical. A pre-measured amount left in a small jar the night before removes even that step from your morning routine.

Why does my tea sometimes have a layer of powder at the bottom?

This is a mixing issue rather than a quality issue. Microground tea is a suspension - the powder disperses through the liquid rather than dissolving the way sugar does, which means it can settle if the cup sits for a while. Stir or swirl the cup before each sip, or use a frother to create a more stable dispersion at the start. Drinking relatively promptly after making also helps, as does making sure the paste step was done thoroughly before adding the full liquid volume.
