  1. The Keurig pod is a pre-measured amount of coffee that will give you the same amount of caffeine regardless of the size you brew. The caffeine content won’t be diluted with the addition of more water, so no, the amount of caffeine from a Keurig pod will be the same whether you choose an 8oz or 12 oz.
    The caffeine will only change if the amount of ground coffee were changed.
    It’s good to know also that roasting affects the caffeine content as well. Roasting actually removes some of the caffeine from the bean, so a light roast will have more caffeine in it that a dark roast does. If your aim is caffeine go for a light or medium roast.

  2. Somewhat. The more caffeine will come out first, so the small will have more caffeine per ounce than the large. But it doesn’t vary greatly.

  3. If anything, it would only be a few milligrams difference because caffeine is so highly soluble in hot water. As soon as the hot water hits the grounds, it is mostly all extracted within one second of contact. I can also confirm that a kcup brewed with 4oz gives me the same buzz as a 10oz cup, I can’t tell any difference.

  4. No.
    The caffeine levels will not differ. Let’s say you’re using the same brand/roast of kcup and make 3 different cup sizes- one 6oz, one 8oz and one 10oz.
    All 3 cups have the same caffeine content. This is because it’s based on the amount of coffee you’re using to brew the cup, not the water volume by which it’s diluted.
    2 TBSP of coffee is 2 TBSP of coffee, no matter how much water you mix it with.

  5. It depends on how the bean is roasted, where its roasted and when its roasted for the level of caffeine you will recieve in your cup.
    The lighter the roast the more caffeine it will have. A hot chocolate will have up to 10mg of caffeine and an espresso and decaf will contain up to 5mg of caffeine. A light roast is 75 to 120mg l. Medium is 60 to 100mg and a dark roast is 50 to 75mg.
    The ounces selected on a machine determines the boldness and wrongness of the flavor of the coffee. For example if you press the strong button on your machine at a 10oz cup size it will slow the brewing process down for a stronger and bolder flavor. Not more caffeine.
    The cup sizes do not determine the level of caffeine.
    Nor does pressing the strong button on your machine.
    If you want more caffeine I suggest going with a breakfast blend. Those are the lightest of the lightest blends. And you can put your favorite creamer in for a great taste.
