Which K cup brand has highest caffeine?

The K-Cup brand known for having the highest caffeine content is typically "Death Wish Coffee." This brand markets itself as the world's strongest coffee, with a caffeine content significantly higher than standard K-Cups. Other brands, like "Green Mountain Coffee" and "Veranda Blend," also offer high-caffeine options, but Death Wish is often recognized for its intensity. Always check the packaging for specific caffeine levels, as they can vary by blend.
