Description 
Maximum Charge is one of the most powerful coffees available anywhere and officially stronger than 'The World's Strongest Coffee'. Made from 100% single-origin speciality grade robusta beans from Rwanda, you can expect a smooth taste with hints of plum and caramel. Traditionally robusta has been seen as inferior to arabica beans but this variety has the taste and complexity of arabica but with a much higher caffeine content. If you need a strong coffee to help you get stuff done, this is the product for you!

Beans
Rwandan robusta (fully washed) - 100%

Strength
This is our strongest and most caffeinated coffee. Don't be fooled by the lack of gimmicky packaging - this bad boy has been lab tested and contains over double the caffeine of regular coffees and more than an number of other products claiming to be the 'world's strongest coffee'. 25g of ground coffee brewed with 250ml of water yields over 400mg of caffeine. This makes it ideal for those times in life when you need a serious boost but we don't recommend drinking more than 2 cups per day.
