Nitro is cold coffee on tap that’s infused with tiny nitrogen bubbles, and the bubbles give this coffee a foamy texture, like Guinness beer. To get nitrogen into the liquid, the tap is a “restrictor plate” to squeeze the drink through tiny holes, giving the beverage a particularly smooth and frothy head.  Nitro coffee has only 5 calories and 0 grams of sugar. The beans the chain uses for its cold brew have a slight natural sweetness to them already, and the nitro’s foamy crema delivers a smooth, thick texture, so you won’t miss the cream or sugar. The features as follows:Easy to install, use and clean; Give home cold-brewers the royal treatment; Take & share it everywhere (home & outdoor activities); Make nitro cold brew coffee easily at home & DIY the best nitro coffee you’ve ever had; The nitrogen effect cuts the acidity that is tied to traditional cold brew, making it easier on the stomach; Cold brewed coffee is less bitter & sour, sweeter & oilier, richer flavor, cold storage for 2-4 weeks.
