What Is Ube? The Purple Yam Behind Every Purple Latte

If you have walked past a cafe in the last year and seen a violet latte in someone's hand, you have already met ube. It is on menus at Starbucks, Costa, and Pret, it is all over Instagram, and it is starting to appear in Indian cafes too. Most people ordering it have no idea what it actually is.

Short answer: it is a purple yam from the Philippines. Longer answer is more interesting.

How to say it

Oo-beh. Three syllables collapsed into two, with the stress on the first. Not "oobie," not "yoob." The word comes from Tagalog, one of the main languages of the Philippines, and it simply means the tuber itself.

Getting the pronunciation right matters more than it sounds. This is an ingredient with a real cultural home, and it is worth naming it the way the people who have been cooking with it for centuries do.

What it actually is

Ube is Dioscorea alata, a true yam. It grows on a climbing vine rather than underground the way most root vegetables do, and it has rough, dark, bark like skin hiding flesh that ranges from soft lavender to deep royal purple depending on the variety and the harvest.

It is native to Southeast Asia and has been cultivated in the Philippines for centuries, where it is not a trend but a staple. It shows up in halaya, a thick sweet jam made by simmering mashed ube with condensed or coconut milk. It goes into pandesal, the soft bread rolls eaten at breakfast. It is a core layer in halo halo, the shaved ice dessert eaten through Filipino summers. Long before it was a latte, it was food.

What it tastes like

This is the question everyone actually wants answered, and "sweet and purple" does not cover it.

Ube is mildly sweet, noticeably less aggressive than an orange sweet potato. The dominant note is a creamy vanilla character, rounded and soft rather than sharp. Underneath that sits a nuttiness that people variously compare to pistachio, hazelnut, white chocolate, or coconut. The texture, once cooked, is moist and dense rather than fluffy.

What makes it work so well in drinks is that the flavour is gentle enough to sit under milk without fighting it. Where matcha brings bitterness and a vegetal edge that some people need to acclimatise to, ube is immediately approachable. There is very little to get used to.

The colour is not food dye

This is the part that surprises people most. That intense purple is not added.

The colour comes from anthocyanins, a family of natural plant pigments. They are the same compounds that make blueberries blue, red cabbage red, and blackberries almost black. In ube, they are concentrated enough that the yam holds its colour through cooking, drying, and milling into powder.

That said, plenty of products sold as ube in the wider market are not doing this honestly. Neon, almost fluorescent purple is a signal that dye has been added, often to taro or purple sweet potato standing in for actual ube. Real ube reads as a rich, muted violet, somewhere between lavender and eggplant. It is vivid but not electric.

Our own ube powder is milled from Philippine purple yam with no added colour, which is why the shade is deep rather than glowing.

Ube is not taro, and it is not purple sweet potato

These three get used interchangeably and they are three genuinely different plants.

Taro is Colocasia esculenta, a corm rather than a tuber, from an entirely different botanical family. Its flesh is white or pale grey with purple flecks, not purple throughout. Most taro bubble tea gets its purple from added colouring, not from the taro itself. The flavour is starchier and earthier, with less sweetness.

Purple sweet potato is Ipomoea batatas, from the morning glory family, not botanically related to ube at all despite looking similar. It is drier, starchier, and more straightforwardly sweet, closer to caramel than vanilla.

Ube is the yam. Moister, sweeter, more aromatic, and purple all the way through without help.

We go deeper on this in our full breakdown of ube versus taro versus purple sweet potato, because the substitutions matter if you are putting it on a menu.

Where you will run into it

The obvious one is the ube latte, which is ube powder whisked with a little hot water or milk into a smooth base, then topped with steamed or cold milk. No espresso unless you ask for it, which means it is caffeine free by default.

Beyond that: soft serve and ice cream, where ube is arguably at its best. Cheesecakes. Doughnuts, which is how the ingredient first went viral outside Filipino communities, via Manila Social Club in New York around 2016. Pancakes, cookies, milkshakes, and increasingly cocktails.

In India it is still early. A handful of cafes and chains have started running it as limited editions and specials, mostly in the bigger cities, but it has not yet become a fixture. That gap is exactly why it is worth paying attention to now.

Why it is having a moment

Ube has been quietly building for a decade, but 2026 is when it broke through. Starbucks put ube drinks on menus across multiple markets. Costa and Pret ran their own versions. Menu appearances across US restaurants have jumped sharply, and industry analysts now list ube alongside pandan and yuzu as one of the defining flavours of the year.

The usual explanation is that it photographs well, which is true but incomplete. Plenty of photogenic ingredients never make it past a single season. What ube also has is a flavour that almost nobody dislikes, a genuine cultural story behind it, and enough versatility to work across drinks, bakery, and frozen formats from a single ingredient. We break down what actually drove the trend separately.

There is a real tension worth acknowledging here too. Filipino bakers and restaurateurs who have been working with ube for years have mixed feelings about it going mainstream, and specifically about it being treated as a colour rather than an ingredient with a home. Worth knowing if you are going to put it on a menu.

The catch

Supply is tight. Purple yam production in the Philippines has been declining, from around 14,000 metric tons in 2021 to roughly 12,500 in 2025, while global demand has gone the other direction. Climate volatility and limited quality planting material are both squeezing farmers.

If that sounds familiar, it is the same shape as the matcha shortage, where demand outran what the supply base could scale to. The practical consequence is the same too: rising prices, and more incentive for cheaper products to pass themselves off as the real thing.

The short version

Ube is a Filipino purple yam, pronounced oo-beh, naturally sweet with vanilla and nutty notes, and genuinely purple without any dye. It is not taro and it is not purple sweet potato. It works in almost anything, it contains no caffeine, and it is the most talked about ingredient in cafes right now.

If you are thinking about putting it on a menu, we supply ube powder wholesale from the Philippines in 250g, 500g, and 1kg packs, with no added colour.
