Here's the coffee that contains the most amount of caffeine
Popularly referred to as NCB, this cold brew coffee is charged with nitrogen to give the beverage a rich sweet flavor and a creamy velvety texture.
Starbucks has listed its version of NCB as having 280 milligrams of caffeine. Which is, hands down, a lot more than its regular cold brew, which contains 205 milligrams of caffeine.
Interested in knowing the difference between iced coffee and cold brew? Say no more. While the concept might sound similar, the two beverages are anything but. Iced coffee is made by brewing hot coffee, letting it cool and then pouring it over ice, a pretty quick process.
On the other hand, cold brew is made by steeping ground coffee in cool water for hours at a stretch. But it is worth the wait because the finished product has a natural sweetness and smoother texture. Since it's made without heat, this beverage is also less acidic.
