Starbucks sells canned nitro cold brew for about $3 per can. We bought an eight-pack to test whether the nitrogen infusion actually delivers smoother coffee, and whether that smoothness justifies the premium.
What Nitrogen Actually Does
Regular cold brew steeps grounds in cold water for 12-24 hours. Nitro cold brew infuses that with nitrogen gas — the same gas used in draft Guinness. Nitrogen creates microbubbles far tinier than CO2 carbonation, producing a creamy, cascading visual effect and a velvety mouthfeel without any dairy.
Here’s the science: nitrogen doesn’t dissolve well in liquid, so it forms tiny suspended bubbles instead. Those microbubbles trick your palate into perceiving sweetness and creaminess that aren’t there. Nitrogen also displaces oxygen, which slows oxidation — acting as a natural preservative that helps maintain flavor.
The can uses a nitrogen widget (like nitro beer cans). When you open it, the pressure change forces nitrogen out of the widget, creating the cascade. Follow the instructions: tilt once, open, pour into a cold glass.
The Taste
Black (10 calories)
Aroma: outstanding. Rich, strong, genuinely premium-smelling.
Taste: noticeably bitter with a slight burnt edge. This is Starbucks’ characteristic dark roast profile — some people love it, others find it too much. The nitro smoothness is undeniably there — the mouthfeel is velvety and full — but it doesn’t overcome the bitterness for casual black coffee drinkers.
With a Splash of Cream
This changes everything. A small pour of half-and-half rounds out the sharp edges completely. The bitterness fades to background, the nitro smoothness takes center stage, and the result is genuinely impressive. Smooth, velvety, and drinkable all day.
If you’re buying this, plan to add cream. That’s where the product shines.
The Numbers
- Caffeine: about 215mg per can (roughly 2 espresso shots — substantial)
- Calories (black): 10
- Price: about $3/can, about $24/8-pack
The Verdict
The nitro effect is real — it genuinely delivers smoother, more velvety texture than regular canned cold brew. But the black version is too bitter for most casual drinkers.
Worth buying if: You like Starbucks’ dark roast profile, you’ll add cream, and you want convenient nitro texture on the go.
Skip it if: You prefer lighter, more balanced cold brew, drink black coffee, or can’t justify $3/can when home-brewed cold brew costs a fraction.

The product is solid. The price is the sticking point. A splash of cream makes it genuinely special — but at that point, you’re customizing a $3 can at home, which somewhat defeats the convenience proposition.

Frequently Asked Questions
- What does nitrogen do to cold brew coffee?
- Nitrogen creates microbubbles far tinier than CO2 carbonation, producing a creamy, velvety mouthfeel without any dairy. The microbubbles trick your palate into perceiving sweetness and creaminess that aren't chemically there. Nitrogen also displaces oxygen, which slows oxidation and helps preserve flavor. It's the same science behind draft Guinness — visual cascade, smooth texture, perceived sweetness.
- How much caffeine is in Starbucks canned nitro cold brew?
- About 215 mg per can — roughly equivalent to two espresso shots. That's substantial. For comparison, a regular 8 oz cup of drip coffee has about 95 mg. One can in the morning provides plenty of caffeine for most people. If you're caffeine-sensitive, consider having only half.
- Is making cold brew at home cheaper than buying canned nitro?
- Significantly. Homemade cold brew costs roughly $0.30-0.50 per serving versus $3 per can of Starbucks nitro. A daily Starbucks nitro habit runs about $1,095 per year; homemade cold brew runs about $110-180. You won't get the nitrogen effect at home without specialized equipment, but the coffee itself is comparable or better in quality.
- Why does Starbucks nitro cold brew taste bitter?
- It uses Starbucks' characteristic dark roast profile, which pushes beans past second crack where char compounds develop. Some people enjoy that bold, smoky intensity. If it's too bitter for you, add a splash of half-and-half — it rounds out the sharp edges completely and lets the nitro smoothness take center stage. The cream transforms the drink from polarizing to genuinely impressive.
