More caffeine. No compromise on flavor. Harper's Max Caf Blend is a high caffeine coffee blended specifically for people who need the extra energy kick without sacrificing the smooth, satisfying taste they expect from a great cup of coffee.
If regular coffee just isn't cutting it anymore, Max Caf is your answer. The strongest coffee blend in the Harper's lineup — bold, smooth, and packed with significantly more caffeine than a standard roast.
How Max Caf Delivers More Caffeine
Most people don't know that light roast coffee has more caffeine than dark roast — because caffeine breaks down during longer roasting. Harper's Max Caf Blend uses a higher proportion of lightly roasted, high-caffeine Robusta beans blended with premium Arabica to create a cup that's both bold in flavor AND significantly higher in caffeine than a standard coffee. Maximum energy, maximum taste.

Frequently Asked Questions
How much more caffeine does Max Caf have?
Max Caf contains significantly more caffeine than a standard Arabica blend — thanks to the addition of high-caffeine Robusta beans and a lighter roast profile that preserves more caffeine during roasting.
Does high caffeine coffee taste different?
Robusta beans have a bolder, more bitter character than Arabica. Harper's Max Caf balances this by blending carefully with premium Arabica for a cup that's bold and strong but still genuinely enjoyable.
Is Max Caf good as a pre-workout?
Yes — natural caffeine from coffee is one of the most effective pre-workout supplements available. Max Caf gives you a significant energy boost in a delicious, natural format.
