Black Rock Coffee publishes caffeine for every drink and size in its official nutrition statement. The short version: an Iced Fuel runs 160 to 270mg depending on size, a canned Fuel is 180mg, a latte is 185mg in the two smaller sizes and 370mg in the two larger ones, and the Iced I.V. sits at 550mg no matter which cup you order. All numbers below come straight from that document (the BRCB 5.26 edition of their master nutrition PDF), which Black Rock notes is approximate and based on standard recipes.
The size jump is the thing to watch
Black Rock's espresso drinks do not scale smoothly. A 16 oz and a 20 oz iced latte both carry 185mg, then the 24 oz jumps to 370mg. Same pattern on hot drinks: 12 oz and 16 oz are 185mg, 20 oz and 24 oz are 370mg. In practice the two large sizes get double the espresso, so moving up one size at the wrong point doubles your caffeine while the price barely moves. If you want the big cup without the big dose, that is what the Fuel line and drip are for.
Two more quirks worth knowing. Frozen Fuel has noticeably less caffeine than Iced Fuel at every size (100mg vs 160mg at 16 oz) because the blended base dilutes the energy drink. And the I.V., their signature breve-style heavy hitter, is 550mg in every size and format, which clears the FDA's 400mg daily benchmark in a single cup. The Jackhammer tops even that at 560 to 565mg in the larger sizes.

Canned Fuel (Original, Sugar Free, or Organic) is 180mg per 12 oz can, which the company also confirms on its FAQ page. An extra espresso shot adds 25mg per the same nutrition sheet, a smaller bump than most chains list for a shot, and Black Rock flags all of its caffeine figures as approximate. The Hot I.V. and Blended I.V. carry the same 550mg as the iced version.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. How caffeine affects you depends on your own tolerance and health, so treat these numbers as information, not advice.

How Black Rock compares to other drive-thru chains
Black Rock's menu logic mirrors the other espresso-and-energy drive-thru chains: a proprietary energy drink line for the fruity crowd, espresso drinks that double up in the big sizes, and one or two deliberately absurd heavy hitters. Their cold brew at 200 to 345mg is stronger per ounce than most of their espresso drinks, which is common across the category.
