Nitro cold brew

Nitro cold brew is cold brew infused with nitrogen (N₂) under pressure and served on tap, producing creamy texture and fine foam comparable to a stout. High caffeine content (160-200mg/330ml). No sugar or milk needed.

Background & Context

Nitro cold brew is cold brew coffee infused with nitrogen gas and served on draft, the same technology used for draught Guinness stout. The nitrogen infusion creates a cascade of tiny bubbles (nitrogen is less soluble in liquid than CO₂, producing smaller, more stable bubbles) that give the coffee a velvety, creamy texture and a persistent foam head resembling Guinness. Nitro cold brew was commercialised at scale by Stumptown Coffee Roasters (Portland) in 2013, one of the first US roasters to serve it on tap, and was popularised nationally when Starbucks introduced a canned and draft nitro cold brew line in 2016-2018. The nitrogen infusion suppresses perception of bitterness and amplifies sweetness: the same cold brew concentrate tastes sweeter and creamier on nitro than poured still, without adding any milk or sugar.

Practical Use

For café operators, nitro cold brew requires a keg and draft system infrastructure (nitrogen tank, regulator, stout faucet), an upfront equipment investment of €500-2,000 that is offset by high margins (nitro cold brew typically retails at €5-7 per 250ml serve) and strong repeat customer demand from health-conscious customers seeking non-dairy, low-calorie indulgence. Operational considerations: cold brew concentrate should be brewed to 1:4 coffee-to-water ratio (higher than still cold brew) to compensate for the dilution effect of nitrogen infusion; the keg should be kept at 4°C and served within 5-7 days of kegging for optimal freshness. For home nitro, small countertop whip cream charger systems (ISI Twist, iSi Gourmet Whip) using N₂O (nitrous oxide, a less precise substitute for pure nitrogen) can approximate the effect at lower cost.
