Cannonball Coffee Company

Cannonball Coffee Company was launched in 2018 by Duncan, an ex-British Army veteran who served for 8 years before founding the business. The proposition is built around high-caffeine coffee that is roasted at medium rather than dark, a deliberate counter to other strong-coffee brands in the UK market that use heavily dark-roasted beans.

The key ingredient is a Robusta variety from Rwanda, verified by lab analysis to contain more caffeine than competitors' claimed strongest offerings. Cannonball roasts in partnership with Beanpress Coffee near Blandford, Dorset.

The business sells online to consumers and wholesale, and also offers portable brew equipment. It currently has over 1,300 verified reviews.
