Short answer: Califia Farms cold brew runs from about 50mg to 270mg of caffeine per serving depending on which bottle you grab. The XX Espresso line is the one most people reach for, and it sits around 90mg per 8 fl oz serving in the multi-serve carton, or roughly 150mg in the 10.5 fl oz single-serve bottle. Numbers below are from the compiled label data at Caffeine Informer, cross-checked against Califia's own product pages.
Why the same brand swings from 50mg to 270mg
Califia does not brew espresso. Every ready-to-drink coffee they sell, including the ones with "Espresso" on the label, starts as cold brew. The naming is about strength and flavor, not method. That is worth knowing at the shelf, because two bottles that look almost identical can be triple the caffeine of each other.
The three things that move the number are roast strength, serving size, and whether it is a concentrate. The sweetened almondmilk drinks like Café Latte and Mocha are the mildest because they are mostly milk. The black cold brews are stronger. And the concentrate is the outlier: 90mg sits in just 4 fl oz because you are supposed to cut it with water or milk before you drink it, so do not treat that number like a finished cup.
One more shelf note. The multi-serve cartons list caffeine per 8 fl oz serving, and a carton holds several servings. If you pour a tall glass you are stacking servings, so a 12 or 16 oz pour of XX Espresso is closer to 135mg to 180mg than the 90mg on the panel.

Source: Caffeine Informer compiled label data. Per fl oz figures are calculated from the listed serving and rounded. Caffeine in any coffee product varies batch to batch, so read these as close estimates, not lab numbers.
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.
Put next to a coffee shop drink, Califia lands where you would expect. A grande brewed coffee at a big chain is often in the 300mg+ range, so a single-serve XX Espresso at 150mg is closer to a small drip or a couple of shots. The Pure Black at 270mg per 12 oz is the one to respect if you are caffeine sensitive, and the concentrate is easy to over-pour if you eyeball the mix instead of measuring.
