What percentage of caffeine is typically removed in the Swiss water decaf process?

The Swiss water decaf process is known for effectively removing caffeine from coffee beans using water and osmosis, without the use of chemical solvents. This method typically removes around 97% of caffeine, which aligns with the standards of quality decaffeination.

Choosing the percentage of 99.9% suggests an extremely high level of decaffeination that isn't representative of the Swiss water method's output. In practice, while this process is very effective, achieving near-total caffeine removal doesn't reflect the realities of the technique and the tiny amount of caffeine that may still remain post-process. Thus, the correct understanding of the Swiss water decaf process indicates that about 97% of caffeine is usually eliminated, making that the most accurate answer for this question.
