Nitro Hazelnut Cold Brew

If you’re building your first nitro drink and want the least fussy flavor to start with, this is a reasonable pick. The syrup here is just cane sugar and real hazelnut extract — no puree, no cream, no spice blend that can settle or clump — so there’s nothing extra to worry about beyond the nitrogen step itself.

What the Nitrogen Part Actually Requires

A jar and a strainer get you plain Cold Brew Concentrate; they don’t get you a cascade. For that you need a whipped-cream-style dispenser (an iSi Gourmet Whip is the standard choice) fitted with a nitro-specific flow-restrictor widget in place of the regular whipped-cream head, or a dedicated nitro cold brew maker with the restrictor built into the unit. Both run on 8g N2 chargers, sold in nitro-labeled packs. The device itself is a real cost to plan for separately if you don’t already own one — the per-drink math below only covers the charger and ingredients.

Make the Hazelnut Syrup First (Just Once)

This recipe assumes you already have a jar of Hazelnut Syrup in the fridge. If you haven’t made a batch yet, go do that first, then come back here — it’s a quick stovetop step that covers about 12 drinks.

Building the Nitro Cold Brew

1. Combine 4oz Cold Brew Concentrate, 4oz cold water, and 2 tbsp of the syrup in your dispenser or nitro maker’s reservoir. Stir or shake gently 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 — colder liquid holds the charge better and cascades more visibly.
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.

Home nitro hazelnut cold brew (concentrate, syrup, nitrogen charge)~$0.97

Savings per drink$5.53

The syrup batch itself is a one-time ~$1.05 and makes about 12 drinks. The nitrogen charge is the other recurring cost: one 8g N2 charger runs about $0.90 (sold in nitro-specific 10-packs for about $9) and charges a 1-pint dispenser or nitro maker reservoir for about 2 pours — that’s ~$0.45/drink. Assumptions: cold brew concentrate at grocery-bean pricing (see the concentrate recipe for the full breakdown), a standard 8g N2 charger, and 12 servings per syrup batch. Flavored nitro cold brew isn’t a fully standardized national-chain menu item the way a plain latte is — some chains sell a plain or sweet-cream nitro, but a full flavor lineup like this one is mostly a specialty/indie-coffee-shop item right now, so $6.50 above is a representative specialty-café price, not one chain’s exact grande price. The gap holds either way. At 5 nitro cold brews a week over the site’s standard 48-week year (240 drinks), that’s roughly $1,327/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.

What This Actually Tastes Like

Clean and classic — the extract carries a genuine nutty flavor that sits alongside the coffee’s own roast character instead of covering it up, and because the syrup has nothing thick or fatty in it, this is one of the crispest, tightest cascades on the whole list. It’s a good flavor to judge your gear against: if the pour looks flat here, the problem is the technique or the charger, not the syrup fighting the nitrogen.

Swaps & Notes

• Extract quality matters more here than almost anywhere on this site. Hazelnut extract strength varies a lot by brand — taste your syrup batch once it’s cooled and adjust the next one up or down before you build a full pitcher of drinks around it.
• Want it less sweet? Drop to 1 tbsp of the syrup instead of 2 — it still nitrogenates exactly the same, just carries less sugar and flavor.
• No dispenser or nitro maker yet? Skip the charging step and you’ve got a regular iced hazelnut cold brew instead — still a genuinely good drink, just without the cascade.

FAQ

Is this made with real hazelnuts?

No — and we’d rather say that plainly than let the name imply otherwise. Like our Standard-tier Hazelnut Latte, this syrup uses real hazelnut extract dissolved into cane sugar syrup, not steeped or blended whole hazelnuts. If you want the whole-food version, our Ingredient-Honest Hazelnut Latte steeps real toasted hazelnuts into maple syrup instead — that version isn’t currently built for a nitro format, so this Standard build is the nitro option for now.

Why doesn’t hazelnut clog the nitro widget the way a thicker syrup might?

Because there’s nothing in it to clog anything — no puree, no dairy, no undissolved solids once the sugar and extract are fully mixed. It’s one of the thinnest, cleanest liquids going into any drink on this list, which is part of why it nitrogenates so predictably.

Why does the flavor sometimes taste stronger or weaker between batches?

Extract strength genuinely varies by brand and even by bottle — it’s the one real inconsistency in this recipe. Taste the cooled syrup before using a full batch and adjust the amount of extract up or down next time if it reads too faint or too sharp.
