High Caffeine Coffee Bags: Red On

10 individually wrapped brew bags filled with our Red On single-origin Robusta. The strongest coffee we make, in brew bag format. Drop a bag in a mug, add hot water, brew, drink. No grinder, no machine, no clean-up. Part of our coffee bags range.

Why these are high caffeine

Red On is 100% speciality Robusta from the Badra Estate in South West India. Robusta has roughly twice the caffeine of Arabica by weight (2.2 to 2.7 percent vs 1.2 to 1.5 percent). A brewed cup of Red On delivers 1,293mg of caffeine per 12fl oz, putting it among the strongest coffees in the world. Strength 5/5.

NHS guidance is 400mg of caffeine per day for healthy adults. Pace yourself.

How to brew a coffee brew bag

1. Drop a bag in your mug.
2. Add hot water (just off the boil).
3. Steep for 3 to 5 minutes. Longer steep, stronger cup.
4. Bin the bag.
