Cold brew is made by steeping extra coarse ground coffee in cool water for 12 to 24 hours, and nitro cold brew is cold brew coffee infused with nitrogen gas. Due to its extended brew times, cold brew coffee is known for its strong flavor. Nitro cold brew offers the flavor richness of cold brew, but the nitrogen gas removes any unpleasant acidic or bitter notes. It requires almost double the amount of coffee grounds to make cold brew, producing a highly caffeinated beverage. Because of the nitrogen infusion, nitro cold brew is more expensive to purchase and create than regular cold brew.
