Quick take: A K-Cup is a brewing format, not a fixed caffeine dose. The amount varies with the coffee in the capsule, the blend and brewing conditions. Use broad category ranges carefully unless the specific product has been tested.
What does Keurig say?
Keurig Canada says coffee K-Cups generally contain about 75 to 150 mg of caffeine per 250 mL cup, depending on roast strength and other factors.
That range is useful for understanding the category. It should not be copied onto an Urban Calm product page as though our specific K-Cup has been laboratory measured at one point inside that range.
Why K-Cups can still vary
The capsule contains a fixed amount of ground coffee, which improves consistency compared with a randomly filled scoop. But the coffee species, blend, roast and actual dose in the capsule can differ across products.
Brew size can also change the finished concentration. A larger cup uses more water through the same capsule. It may extract somewhat more caffeine, but it also spreads the beverage across a larger volume.
What about Urban Calm K-Cups?
Urban Calm mushroom coffee K-Cups are made from real caffeinated coffee. The mushroom ingredients do not remove that caffeine. Until we have SKU-specific lab results under a defined brew condition, the most accurate wording is that our K-Cups contain caffeine and that the exact amount can vary.
If you are choosing between formats, see Whole Bean, Ground or K-Cups?. If the bigger question is mushroom coffee itself, see Does Mushroom Coffee Have Caffeine?
The useful takeaway
Single-serve brewing is consistent, but not chemically identical across every brand and roast. Treat caffeine ranges as category guidance unless a specific product has been tested.
