Nitrogenated coffee is coffee that has had nitrogen added to it. This gives the coffee a creamy, frothy texture and a slightly sweet taste. It is often served cold or over ice There are a few key trends in nitrogenated coffee technology. One is the use of lower pressure to nitrogenate coffee, which results in a smoother, less acidic beverage. Another trend is the use of nitrogen in canisters or cartridges, which allows for a more consistent nitrogenation process. Finally, some companies are beginning to experiment with using nitrogen in kegs, which could potentially lead to a more cost-effective way to nitrogenate coffee on a large scale.
