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

Maximum Charge is the strongest coffee in the UK. It's made from highly caffeinated single-origin Robusta coffee beans. Medium roast for a really smooth & complex taste, with notes of dark chocolate and toasted malt. Unlike other strong coffees it is not over-roasted and bitter. With over twice the caffeine of regular coffee Maximum Charge will make you become a morning person.

DETAILS

Bean
Single-origin Rwandan Robusta (fully washed) - 100%

Caffeine Content
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?
For more information on the best grind type for your coffee maker head to the making coffee section.

 

What if I don't find it strong?
This is a medium roast coffee. If you prefer the rank, bitter taste of a dark roast you'll find this coffee pretty mellow. 

Money Back Guarantee
If you don't love it, we'll give you your money back.
