Ube Nitro Cold Brew

Ube’s viral purple color and creamy, mildly vanilla flavor pair well with nitro cold brew’s own dense, cascading foam — the two textures play off each other visually as much as they do in flavor. This uses the same real ube halaya syrup as our Ube Latte and Ube Mocha, not a bottle of purple dye.

The Gear You Actually Need

We’re not going to pretend this happens with nothing but a jar, the way our plain Cold Brew Concentrate does. Nitro cold brew genuinely requires one of two things: a whipped-cream-style dispenser (like an iSi Gourmet Whip) fitted with a nitro-specific flow-restrictor widget — not the regular whipped-cream head, which won’t create the cascade — or a dedicated nitro cold brew maker, a countertop device built specifically for this that bundles the charge and the restrictor into one unit. Either route needs 8g N2 chargers. Budget real money for the device itself if you don’t already own one; the per-drink math below only covers the charger and ingredients, not the dispenser or maker itself.

Make the Ube Syrup First (Just Once)

This recipe assumes you already have a jar of Ube Syrup in the fridge — real ube halaya thinned to a pourable syrup. If you haven’t made a batch yet, go do that first, then come back here — it covers about 10 drinks.

Building the Nitro Cold Brew

1. Combine 4oz Cold Brew Concentrate, 4oz cold water, and 2 tbsp of the ube syrup in your dispenser or nitro maker’s reservoir. Stir or shake so the syrup fully dissolves before charging.
2. Charge with one 8g N2 charger per your device’s instructions, then shake or invert exactly as directed.
3. Chill for at least 30 minutes.
4. Dispense slowly into a chilled glass, nozzle close to the glass, to get the full cascading pour. Add ice after, not before, if you want it colder.
5. Serve immediately — the texture is best in the first few minutes.

Specialty/boutique café nitro ube cold brew~$5.95

Home nitro ube cold brew (concentrate, syrup, nitrogen charge)~$1.65

Savings per drink$4.30

The syrup batch itself is a one-time ~$7.65 and makes about 10 drinks — the ube halaya jar itself is the bigger cost driver versus this site’s other syrups, which is reflected honestly in both this and the Ube Latte’s math. The nitrogen charge is the other recurring cost: one 8g N2 charger runs about $0.90 (sold in nitro-specific 10-packs) and charges a dispenser for about 2 pours — that’s ~$0.45/drink. Assumptions: cold brew concentrate at grocery-bean pricing, a standard 8g N2 charger, and 10 servings per syrup batch. Ube isn’t a standing national-chain menu item, and a nitro-specific ube build is mostly a specialty/indie-shop item right now, so $5.95 above is a representative specialty-café price. At 5 nitro cold brews a week over the site’s standard 48-week year (240 drinks), that’s roughly $1,032/year saved versus the café version — on top of whatever you paid for the dispenser or nitro maker itself, which isn’t in that number.

Swaps & Notes

• No dispenser or nitro maker yet? Skip the charging step and you’ve got a regular iced ube cold brew instead — see our Ube Coconut Cold Brew for a full non-nitro version built around the same flavor.
• No coffee at all? See the Ube Dirty Soda for a coffee-free version of this same syrup.
• Cascade looking flat? Same troubleshooting as every nitro recipe on the site: check the charger was fully seated, the liquid was cold enough before charging, and you’re using an actual nitro flow-restrictor widget, not a plain whipped-cream head.
• Where do I actually find ube halaya? See the sourcing note on the Ube Syrup page — Filipino grocery stores and online specialty retailers are the most reliable options.

FAQ

Is the purple color from real ube or food coloring?

Real ube halaya (purple yam jam) — see the Ube Syrup recipe for the sourcing and batch method. This is the same honest-ingredient approach used across every ube recipe on the site.

Do I need actual nitrogen tanks for this?

No — like every nitro recipe here, this uses standard 8g N2O (nitrous oxide) whipped-cream-style chargers paired with a nitro-specific flow-restrictor widget, not true N2 gas. See our Nitro Vanilla Cold Brew FAQ for the full explanation.

Can I make this without buying a dispenser or nitro maker?

Not the nitro part specifically — there’s no stovetop or shaking-by-hand substitute that actually works. Without one, you’d be making our Ube Coconut Cold Brew instead, which is still a genuinely good drink, just a different one.
