Recipe
The ube matcha latte is the drink that finally made layered coffee-shop theatre work with matcha, and it has been climbing hard in Indian search this year. It is a purple yam base under a green matcha top, and the only difficult part is getting the two layers to stay where you put them. That is a density problem, and density problems have arithmetic answers.
The short answer. Sweeten an ube base and put it at the bottom. Keep the matcha layer unsweetened and pour it slowly over the back of a spoon onto ice. Sugar makes liquid heavier, so the sweet layer must go first or the drink will mix itself.
Ube is Dioscorea alata, a purple yam, and it is a staple of Filipino desserts rather than a flavouring invented for cafes. The colour is real and comes from anthocyanins, the same pigment family as blueberries and red cabbage. The taste is mild, nutty and vanilla-adjacent, closer to sweet potato than to taro, which it is frequently confused with. Taro is paler, starchier and more savoury. If a shop sells you a bright purple taro drink, the colour is almost certainly added.
Two liquids stay layered when the lower one is denser. Dissolved sugar is the cheapest way to add density, so the rule is simple: sweeten the bottom layer, not the top. Put the sweetened ube base underneath and float the unsweetened matcha above it. Reverse that and no pouring technique will save you.
Then pour gently. Fill the glass with ice first, because ice breaks the falling stream and dissipates its energy, and pour the matcha over the back of a spoon held just above the surface. The spoon spreads the flow sideways instead of letting it punch down into the layer below.
Three routes, in descending order of quality and ascending order of convenience.
Ube is sweet, creamy and assertive, so a delicate ceremonial grade will simply lose. Use a premium culinary or a mid-tier ceremonial grade with enough bite to read through the purée. This is a good use for the daily-drinking tin rather than the special one. The India brand rankings compare price per gram if you want to find one cheaply.
Layering depends on density differences that heat destroys, because convection currents in a hot drink mix the layers within seconds. Serve this cold. If you want it hot, make peace with a single blended purple-green drink, which tastes the same and looks worse.
A naturally purple ube layer is a dusty violet. The electric purple in most social media photographs is extract, colouring, or editing. The same applies to the green above it: if your matcha layer looks yellow-tinted against the purple, that contrast is showing you something real about the powder, and the colour of matcha is a genuine quality signal worth understanding.
Add sweetness to the ube layer only. That keeps the density gradient working in your favour and preserves the matcha's savoury contrast, which is the entire point of the pairing. Stirring the finished drink is not a failure, incidentally. It is meant to be looked at, then stirred, then drunk.

Mild, nutty and vanilla-adjacent, closest to sweet potato. It is naturally sweet and creamy, which is why it pairs well with matcha's savoury, slightly bitter edge. It is not the same as taro, which is paler, starchier and more savoury.
Sweeten only the bottom layer. Dissolved sugar makes liquid denser, so the sweetened ube base sinks and the unsweetened matcha floats. Then fill the glass with ice and pour the matcha slowly over the back of an upside-down spoon so the stream spreads sideways instead of punching down.
Yes, and most cafes do. Extract is consistent and cheap, and it is where the very bright purple in most photographs comes from, usually with added colouring. Real steamed ube gives a duller violet and much better flavour, so pair extract with condensed milk to make up the difference.
No. Ube is a purple yam, Dioscorea alata, and its colour comes from natural anthocyanins. Taro is a different plant, paler and starchier with a more savoury flavour. A vividly purple taro drink has almost certainly been coloured.
You can, but it will not stay layered. Convection currents in a hot drink mix the layers within seconds. Hot, it becomes a single blended purple-green latte, which tastes the same and looks considerably worse.
A premium culinary or mid-tier ceremonial grade. Ube is sweet and assertive, so a delicate first-harvest ceremonial matcha gets lost entirely and its price is wasted.
