Voted one of the World's strongest coffee beans

Coming in at a whopping 1293mg caffeine per 12 fl oz brewed, our coffee has been voted one of the strongest coffee brands in the world! A strong coffee that is very high in caffeine, so it not for the faint hearted, that's why this is our only coffee that has a strength ratio of 5/5.

The Strongest Coffee We Roast

Need a strong coffee that gives you the same rush as jumping out of an aircraft? Red On! Coffee is our highest caffeine coffee, a single-origin Robusta that will give you the kick you need. So, if you are looking for high caffeine coffee beans or high caffeine ground coffee, then you've found the strongest coffee here!

Single Origin 100% Speciality Robusta

A single origin 100% speciality Robusta from the Badra Estate in South West India. A perfectly balanced, clean coffee, high in caffeine with a sweet and subtle acidity.

Best served as an espresso or brewed by cafetiere.

Arabica or Robusta beans?

Most coffee drinkers default to Arabica. It is smoother, sweeter, easier on the palate. Robusta has roughly twice the caffeine of Arabica by weight, which is why it is the bean of choice when you need real caffeine and a genuinely strong coffee.

Cheap Robusta has earned a bad reputation because most of it ends up as filler in low-grade instant coffee. Single origin speciality Robusta, grown and roasted properly, is a completely different product. That is exactly what Red On is.

Red ON! is hands down the strongest coffee we have roasted, with a very high caffeine content that most people would be scared to try, but still produces a quality serving.
