What does adding nitrogen do for coffee?

It gives it a smoother mouthfeel.

Let me start by saying that I don’t drink coffee. My understanding is that the nitrogen bubbles adds just a hint of sweetness & a lush, velvety smooth texture to the drink. I do know that many vendors have started packing coffee in nitrogen instead of oxygen packaging in order to preserve the freshness. They say that nitrogen is cheaper to produce & delivers a better tasting product.

It’s their iced coffee. Nitrogen is the gas in Guinness Stout. Yes it is mouth feel and adds a creaminess to the drink.

^ I don’t drink iced coffee either. I don’t like the taste nor smell of coffee!!! I also don’t care for the taste of beer so never tasted Guinness either.

It does reduce exposure to oxygen so might enhance ‘freshness’.
