A recent certified lab test found that an average sample contained 310 mg of caffeine per 100ml when using 4 oz (56g) of ground coffee beans to 12 fl oz (355ml) of water. This is the recommended way to brew Maximum Charge.

Maximum Charge uses Robusta coffee beans sourced from the Coko region in Rwanda.
