How long does nitro cold brew stay fresh?
In a sealed pressurized keg, the coffee itself stays good for several days to about two weeks, and it holds its charge as long as pressure remains. Once poured, drink it within a minute or two while the head is at its peak.
Is nitro cold brew stronger in caffeine?
Not inherently. The caffeine comes from the cold brew base, not the nitrogen. It can taste bolder and is often served without dilution, but ounce for ounce it is not automatically more caffeinated.
Conclusion
Learning how to make nitro cold brew comes down to four repeatable moves: brew a clean strong base, chill it thoroughly, charge it with nitrogen, and pour hard for the cascade. Nail those and you will pour a creamy, cafe-quality glass at home for a fraction of the price. Start with whatever dispenser fits your routine, dial in your cold brew strength, and enjoy that velvety head every single time.
