Coffee is something that is not only the second most consumed beverage on the planet behind water but for many people it's the fuel that gets them through their day (or at least until mid-morning!). But, HOW coffee is brewed is not something many people put thought into. They buy coffee makers because their last one died, they see one at the store on sale and it will do the trick, or a friend has one that seems like the next best thing.
But if health matters to you, the coffee BREW METHOD you use should also matter.
Unfiltered coffee brew methods including French press and espresso have high levels of oily compounds called Diterpines, Cafestol and Kaweol specifically. You’ve undoubtedly seen the oil slick floating on the surface of the coffee, well, now you know what it is. There is also quite a bit of published research that shows those compounds may not be good for you. According to Dr. David Moore, Professor of Molecular and Cellular Biology at Baylor College of Medicine, Cafestol is the most potent cholesterol-elevating compound known and according to Dr. Marie-Louise Ricketts, a postdoctoral student and first author of the report, French press coffee and espresso contain the highest levels of Cafestol.
For more in-depth information on this research here are a couple of articles that go into more detail:
Cold brewing coffee dramatically reduces these oily compounds in coffee. Cold brewing uses no heat to brew and involves a steeping process of 12 or more hours so you are brewing coffee in the most natural coffee brewing process possible.
At BodyBrew we wanted to know more about how various coffee brew methods might impact the healthiness of the coffee they produce. We wanted to compare our cold brew extraction method with other brew methods, so we conducted third party lab tests. We discovered that French Press had 697% (6X) more Cafestol, Single Serve had 5177% (51X) more Cafestol and wait for it…Espresso had 7621% (76X) more Cafestol (yes you read that correctly!). Great news for health conscious coffee lovers!
What’s great about cold brew coffee is that after brewing you have a super-concentrated coffee extract can then be diluted with hot or cold water, or milk, to create delicious and healthy hot coffee, lattes, iced coffee drinks and cocktails in seconds. You can even add the extract to make delectable desserts too. Here’s a hint, when you're drinking your last serving of cold brew start the next brew process and in 12-24 hours you’ll have 8-12 servings of cold brew coffee, ready when you are!
