Technically yes lighter roast has more caffeine in the beans because less is burned off.
However, you use more darker roast because lighter roast is heavier (because darker is effectively more dry). Also because the darker roast is more roasted, the caffeine in the beans may be more easily accessible/dissolvable.
Yeah I’m a huge fan of James but no one measures by weight really unless you’re a nerd like us. So hence why I said if measured by volume specifically.
Weirdly enough, lighter roasts have more caffeine typically if measuring by volume.

I think roughly it evened out in the end.
