1 cup of exhale coffee = 12 punnets of blueberries, 55 oranges or 1.2kg of kale!!

(in terms of its antioxidant power that is...)

In September 2020 we hired an independent UK lab to test the antioxidant power of our coffee vs fruit & veg. We bought them a grinder and cafetiere and sent them our exact brewing instructions. We even paid them to pop out to their local supermarket on the morning and buy the fruit & veg fresh on the day to get a real comparison of a brewed cup of exhale coffee vs the kind of stuff you actually buy and eat everyday.
I'd read the research saying coffee can be one of the most prolific antioxidants in our diets but wasn't quite prepared for just how potent ours was...
1 cup of exhale coffee = 1.8kg of blueberries, 55 oranges or 1.2kg of kale! 🤯
The owners of the lab, and the inventors of the very test themselves, said they couldn't believe their eyes.
The below link is to the full report they issued to us. It's not designed to be peer reviewed, we didn't use a big enough sample size for that, but what it does do is paint a clear picture as to why we think exhale coffee should be part of your diets, today!

Hi Team, this sounds like a fantastic product although I am yet to try some. Thank you for the transparency with the report. Do you know what percentage of the polyphenols are lost during the process of decaffeination?
What method do you use for decaffeination? Solved or CO2 are two I’ve read about. Thanks,
Frazer

Absoloutely amazing coffee. The best I’ve ever had the pleasure to drink.

Hi there – is your decaf as potent in antioxidants as your caffeinated versions?
Ollie
Great to see you’re testing the coffee. Have you compared to other coffee brands?

Hey Ben, thanks for the message.
We test for total polyphenols and chlorogenic acid with every shipment and it’s those that give coffee it’s antioxidant potency. And often inbetween shipments too. Have you seen our Our Process page? https://exhalecoffee.com/pages/our-process I have recently added a new batch of certificates there. Plus I’m currently co-ordinating a mass investigation, working with a speciality roasting consultant, to see if we can come up with some imaginative new roasting techniques to push those numbers further. So we’re always working on it!
Also check out my recent blog on polyphenols for a whole different side of testing I’ve been doing myself to try to find the best way to brew coffee. Because how you brew it at home has a massive impact on how much is extracted too.

On that, also check out my Complete Guide to Brewing Healthy Coffee for tips and tricks there too.

Finally, because brewing is so important I’m also working with a factory direct to invent a new coffee brewing device to maximise the polyphenol extraction! So watch this space on that too.
Hope that helps reassure you of the level of nerdery going on at Exhale behind the scenes!
Best,
Al
