Step by step

  1. 1

    What is nitro cold brew?(Concept)

    Cold brew infused with nitrogen gas — creates a cascading pour, creamy mouthfeel, and natural sweetness without sugar. The tiny nitrogen bubbles create a Guinness-like cascade and velvety texture. Market hit $92M in 2025, growing 21% annually.

  2. 2

    Option 1: Whipped cream dispenser + N2O chargers (£30-50)(Equipment)

    Most accessible home method. Use a standard 0.5L whipped cream dispenser (iSi, Mosa) with N2O (nitrous oxide) chargers — NOT N2 (nitrogen). N2O dissolves better in cold liquid and creates similar texture. Make cold brew concentrate (1:8 ratio), charge with 1-2 N2O cartridges, shake 30 seconds, dispense. Cost: ~£0.50 per serve for chargers.

  3. 3

    Option 2: Mini keg system (£80-150)(Equipment)

    Systems like the uKeg Nitro or GrowlerWerks uKeg use true N2 cartridges and a tap. Better for larger batches (1-2L), true nitrogen (not N2O), and you can keep it pressurised for weeks. Best for: serious cold brew drinkers, entertaining.

  4. 4

    Option 3: EverNitro (new 2026)(Equipment)

    Debuted at CES 2026 — a countertop device that generates 95% pure nitrogen from ambient air. No cartridges needed. Makes nitro cold brew on demand. UK availability TBD but worth watching — could be the game-changer for home nitro.

  5. 5

    Making the cold brew base(Recipe)

    1:8 ratio (125g coffee : 1L water). Coarse grind (French press setting). Steep 18-24 hours at room temp or fridge. Filter through paper (V60/Chemex filter) for clarity. Dilute 1:1 with water or milk when serving. The concentrate keeps 2 weeks in fridge.

  6. 6

    Serving nitro at home(Technique)

    Pour hard and fast into a pint glass — the cascade happens on impact. Use a stout/pint glass for the full visual effect. Don't add ice to the glass first — it disrupts the cascade. Add ice *after* pouring if you want it colder. Drink immediately — nitro texture degrades over 10-15 minutes.

Barista tips

  • Use N2O (whipped cream chargers) not N2 — cheaper, easier to find, similar texture.
  • Filter cold brew through paper before charging — sediment clogs dispenser nozzles.
  • Barista oat milk + nitro = incredible vegan 'Guinness' texture.
  • EverNitro (2026) could eliminate cartridge costs — watch for UK launch.

Frequently asked questions

Yes — it's food-grade, used in whipped cream for decades. The amount dissolved in a serve is tiny. It creates a slightly sweeter perception than N2 but the texture is nearly identical. True N2 systems cost more and cartridges are harder to find.
