Essentially yes, but it depends on a variety of factors; the type of coffee beans used,, the size of your grind, the extraction (brewing method) used to make your cup of coffee and so on. Essentially, some light roasts could have more caffeine in less scoops than a dark roast, but using more scoops of that dark roast could match the caffeine content of the light roast and even surpass it if you use more scoops.
