Liquid Nitrogen Dosing - Coffee
The addition of Liquid Nitrogen to ready-to-drink coffee products just after filling adds pressure to aluminum cans. This provides the can with some rigidity making it more stable. Liquid Nitrogen dosing can also help reduce O2 in the headspace preserving the flavor and aroma of the coffee.
As cold-brew coffee continues to grow in popularity, more companies are looking to add nitro-coffee to their offering. The same equipment used for pressurization can also be used to nitrogenate coffee to get the smooth, creamy, and attractive cascade effect after pouring, with or without a widget.
