Someone had told me that Decaf Coffee?

Question

Some had told me that Decaf Coffee is not 100% decaffinated. What is the percentage of caffine in Decaf?

Answer 1

decafination is a facinating process where they subject the coffee beens to carbon dioxide or oxygen in supercritical fluid state which absorbes the caffeen. There is a chance that it does not absorb out all of the caffeen, but it takes most of it...I dont have a percentage for you because it varies.

Answer 2

The best and most expensive process is the Swiss water process.

It removes about 90% of the caffeine.

Always buy "Swiss Process Decaf".

Answer 3

Decaf coffee is 99.9 decaf.

Answer 4

That is true.  I'm not sure what the percentage is, certainly not enough to get worked up about.
