Black Rock Coffee Bar Caffeine Guide
One caffeine figure on this menu is published where anyone can check it: the I.V. line. The Iced, Hot, and Blended I.V. each carry 384 mg of caffeine and six shots of espresso, flagged right on the menu. At $8.05 - $8.80 for the iced version, it is also one of the priciest signatures.
Six shots, 384 mg. The I.V. is the only drink on the menu with a printed caffeine figure, flagged on the menu itself.
What About Everything Else?
The chain does not print caffeine values for its other drinks in the listings we can verify, and the Fuel line's caffeine content is not published either. Plenty of sites fill that gap with estimates presented as facts. We would rather tell you the honest state of the data: beyond the I.V., treat any exact milligram number you see online as unverified unless it points to the chain's own nutrition document.
The Practical Ranking
What can be said from the menu itself: the I.V. (six shots) sits alone at the top, the Jackhammer adds an extra double shot to a vanilla mocha, and standard espresso drinks follow their shot counts. The Protein Cold Foam Fuels and regular Fuels are energy drinks whose caffeine the chain has not published.
