Where it comes from

Our ube is grown and harvested at peak season by farms in the Philippines, the native home of purple yam. It's gently dried at low temperatures, finely milled and sealed in a GMP-certified facility to protect colour, flavour and nutrients. Every batch is tested by an independent laboratory for heavy metals and microbiology before it ships. No colouring, no fillers, no additives. If it isn't pure ube, it doesn't ship.

What's on the bag is what's in the bag

Three reasons to go purple

Caffeine-free energy

Slow-release starch gives you a steady, even lift instead of a spike and a crash. Have one at 4pm. Have one at 9pm. Sleep fine.

Gut health

6.5g of fibre per 100g and naturally rich in resistant starch, the food your good gut bacteria actually want. Gentle, not acidic.

Rich in antioxidants

The purple is anthocyanin, the same plant pigment as blueberries and blackcurrants. We never add colour. The yam brings its own.

The science, briefly

Where the purple comes from

No lab-made "proprietary blend", just a very good root vegetable and a few facts worth knowing.

🍠

The colour is the proof

Ube's deep violet comes from anthocyanins, the pigment family behind blueberries and blackcurrants. It shifts slightly with pH, so oat milk, dairy and almond each give you a different purple. That's how you know it's real.

🌾

6.5g of fibre per 100g

Purple yam is naturally high in fibre, and much of its starch is resistant starch, which passes through to your gut rather than being absorbed straight away.

Slow-release, caffeine-free

Ube's starch granules are small and dense, so they break down gradually rather than all at once. That's where the steady, even feel comes from. There's no caffeine in it at all.

🌿

Prebiotic by nature

Resistant starch is what gut bacteria feed on. In studies on Dioscorea alata, the same species as our ube, its resistant starch has been shown to encourage Bifidobacteria and the short-chain fatty acids they produce.

Café maths

£5.50 at the coffee shop. £0.92 at home.

A shop-made ube latte is usually a sweetened syrup or a pre-mixed powder. One bag of YumYam makes about 25 real ones, and on subscription that's under a pound a cup.

Finally, ube that tastes like home

Grew up on my lola's ube halaya so I'm picky. Most powders taste fake or chalky. This is the real thing, and the frother makes it properly frothy.

The 2pm crash is gone

Mum of two with a full-time job, so I was living on coffee and paying for it every afternoon. Now it's an ube latte at 2pm instead and I'm not wired at bedtime.

One ingredient. Flip the label.

I've been burned by "superfood" blends with 40 ingredients and mystery "natural flavours". This is literally just organic purple yam. Bought the mug too, no regrets.

FAQ

Before you add to cart

Does it dissolve easily? Do I need to cook it?

No cooking. Whisk a teaspoon with a splash of hot (not boiling) water into a smooth purple paste using your free frother, then add your milk of choice. Straight into cold milk it'll need a good shake or blend.

Which milk works best?

Oat milk gives the creamiest, most café-style cup and the deepest purple. Dairy is a close second. Almond and coconut are lighter and let the vanilla notes come through. There's no wrong answer.

Why is my latte pink one day and deep purple the next?

That's the proof it's real. Ube's colour comes from anthocyanins, the same pigments as in blueberries, and they shift with pH. Different milks, a squeeze of lemon, even your tap water can nudge the shade. Artificial colouring never does that.

Will it spike my blood sugar? Can I drink it in the evening?

Ube is high in resistant starch, which digests slowly rather than releasing all at once, and there's no added sugar; the 0.3g in a cup occurs naturally in the yam. With zero caffeine, plenty of our customers use it specifically as the after-dinner drink they can't have coffee for. If you have a medical condition, check with your GP as you would with any new food.

I don't like matcha. Will I like this?

Probably, because they're nothing alike. Matcha is grassy and bitter and usually needs sugar. Ube is naturally sweet with vanilla and hazelnut notes and needs nothing added.

How does the subscription work? Can I cancel?

A fresh 100g bag arrives every month for £23 instead of £30, always with free UK delivery. Pause, skip a month or cancel any time from your account in one click. No minimum term.

Which certifications does YumYam hold?

YumYam is USDA Organic, 100% vegan, non-GMO and naturally gluten-free, with every batch independently lab tested for purity before it ships.
