Quick answer: A nitro cold brew setup needs cold brew, kegs, a nitrogen source (high-pressure cylinders or a nitrogen generator), a regulator and lines, a kegerator, and a stout faucet, or an inline nitrogen infusion system. Plan for gas safety (secured cylinders, leak checks, ventilation), regular line cleaning and food-safe holding. It works best where cold brew already sells well and customers will pay a premium.
Key takeaways
- Two approaches: infuse in the keg, or inline at the tap.
- Nitrogen source: cylinders or a generator.
- Safety: nitrogen is an odorless asphyxiant in enclosed spaces.
- Cleaning: lines and faucets on a schedule.
Why nitro
Nitrogen creates tiny bubbles that give cold brew a creamy texture and a cascading pour, without dairy or sugar. Cold coffee demand keeps growing: 21% of past-day coffee drinkers had a cold coffee in NCA's fall 2026 data. Nitro is a way to stand out and charge more for a drink you already make.
The equipment
| Component | What it does | Notes |
|---|---|---|
| Kegs (often 2.5–5 gal) | Hold cold brew | Corny or Sankey style |
| Nitrogen source | Cylinders or generator | Generators make nitrogen from air |
| Regulator | Sets gas pressure | Must be rated for nitrogen |
| Gas lines and fittings | Carry gas | Use beverage-grade, leak-tested |
| Kegerator or keg fridge | Keeps cold brew cold | Size for 2+ kegs |
| Stout faucet | Creates the cascade | Restrictor plate is key |
| Inline infuser (optional) | Infuses nitrogen at the tap | Can avoid pre-charging kegs |
Keg infusion vs. inline infusion
- Keg infusion: charge the keg with nitrogen at higher pressure and let it absorb, then serve through a stout faucet. Simple equipment; takes time to infuse.
- Inline infusion: cold brew flows through a device that infuses nitrogen on demand. Faster turnaround; more equipment and cost.
Gas safety
Nitrogen and carbon dioxide are colorless, odorless asphyxiants. Victoria, Australia's workplace safety regulator, WorkSafe, warns that beverage gas leaks can build up in enclosed cellars and cool rooms and overcome people without warning. Practical controls:
- Secure cylinders upright with chains or brackets.
- Store in ventilated areas, not small enclosed closets or walk-ins.
- Leak-test connections with bubble solution after every cylinder change.
- Consider an oxygen monitor where nitrogen is stored in enclosed spaces.
- Train staff on changing cylinders and what to do if an alarm sounds.
- Follow your gas supplier's instructions and local fire code.
Food safety and cleaning
Cold brew isn't brewed with boiling water, so cleanliness matters. University of Georgia researchers found that pathogens can survive in cold brew for days, with contamination from equipment being a key risk.
- Clean kegs between fills with approved cleaner and sanitizer.
- Clean lines and faucets on a regular schedule (many operators do it weekly or every keg change).
- Label kegs with brew and fill dates.
- Keep everything cold from brewing to serving.
Costs and math
Illustrative: a basic two-keg setup might cost a few thousand dollars, and inline systems or generators more. If nitro sells for $1.00 more than regular cold brew and you pour 40 a day, that's $40 a day or roughly $1,200 a month in extra revenue. Subtract gas and cleaning labor to estimate payback.

Serving tips
- Serve without ice to preserve texture, or with minimal ice.
- Use a clear cup to show the cascade.
- Offer a sweet cream or cold foam option for customization.
- Sip lids keep the foam head; straws pull from below it.
Show off the cascade
Affogato Bean doesn't sell nitro equipment directly, but we help cafés source equipment and print branded clear cold cups and sip lids that show off every pour. Talk to us.

Frequently asked questions
What do you need to serve nitro cold brew?
You need cold brew, kegs, a nitrogen source (cylinders or a nitrogen generator), a regulator, gas lines, a refrigerated kegerator or keg fridge, and a stout-style faucet. Some systems infuse nitrogen inline instead of in the keg.
Is nitrogen gas dangerous in a coffee shop?
Nitrogen is colorless and odorless and can displace oxygen in enclosed spaces. Store and connect cylinders safely, secure them upright, check for leaks, and keep storage areas ventilated. Follow your gas supplier's and local fire code requirements.
Is nitro cold brew worth it for a café?
It can be, if you have steady cold brew demand and can charge a premium. The equipment cost and cleaning time are real, so estimate servings per day before buying.
