Our specialty decaf coffees are decaffeinated using the chemical-free Swiss Water decaf process.
BUY DECAF COFFEE
For those with a low tolerance to caffeine, decaffeinated coffee is the answer.
However, for many years, decaf coffee has suffered from a poor reputation as failing to live up to the taste of caffeinated coffee.
While, in the past, this may have been the case, things are completely different now.
In fact, at Cast Iron Coffee Roasters, we absolutely love a good decaf coffee.
As always, however, we are pretty picky about what decaffeinated coffees we offer our customers.
That is why we only roast and sell decaf coffee that has been decaffeinated using the Swiss Water process.
This method involves absolutely no chemicals in the decaffeination process, relying exclusively upon caffeine’s inherent solubility
and the power of osmosis to remove caffeine directly from the green beans that we buy and roast.
Frequently Asked Questions About Decaf Coffee
What is the Swiss Water process?
The Swiss Water process of decaffeinating coffee is entirely natural, involving no chemicals or artificial methods at all.
The Swiss Water process was created in 1930s Switzerland (hence the name), reaching commercial coffee production by the 1980s. But how does it work?
First, normal green coffee beans are soaked in hot water, which dissolves the caffeine.
It can, however, dissolve some other components in the bean which contribute to its amazing flavour and aroma.
To get this good stuff back into the bean, the water solution is then passed through a very fine charcoal filter.
While the caffeine gets trapped in the filter, the sugars, oils and other flavour components pass through, creating a solution called Green Coffee Extract.
The Green Coffee Extract is then used to soak the next batch of green beans.
Because this solution already contains all the good stuff, all that good stuff won’t dissolve from the new batch of beans, so just the caffeine is removed.
The whole process takes between 8 and 10 hours, but is highly effective at removing 99.9% of caffeine without affecting the flavour of the coffee. Ta-da!
How much caffeine is there in Cast Iron Coffee Roasters’ decaf coffee?
The Swiss Water process removes 99.9% of caffeine from the green coffee bean.
For a standard 12oz cup of coffee, which would contain anything between 120-160mg of caffeine,
the decaf version would contain less than 2mg.
Is decaf coffee good for you?
All coffees contain a high level of antioxidants, which are really good for you.
These are not lost during the Swiss Water decaffeination process.
