“First high caffeine coffee that lives up to its tout as highly caffeinated, medium roast and smooth to drink” Jeffery O

Need help getting shit done? Then we have the coffee for you.

Maximum Charge contains significantly more caffeine than other brands claiming to be the 'World's Strongest'. 

The difference between this and other strong coffees is its smooth, mellow flavour. It is a lighter roast from single-origin speciality grade robusta beans from Rwanda. You can expect a smooth taste with hints of dark chocolate and toasted malt. 

Bean
Rwandan robusta (fully washed) - 100%

Strength
Lab analysis shows that 25g of ground coffee brewed with 250ml of water gives you over 400mg of caffeine. We do not recommend drinking more than 2 cups per day. 

Which Grind?

What if I don't find it strong?
Because this is a medium roast, people who are used to burnt & bitter dark roast coffee can be surprised by the subtle taste. Trust us, Maximum Charge packs a punch.
