Does Decaf Mean No Caffeine

Does Decaf Mean No Caffeineの注目ポイントを丁寧に掘り下げてご紹介します。

Here’s the honest truth: A typical cup of decaf still has about 2 to 5 milligrams of caffeine. Compare that to regular coffee’s 95 milligrams—it’s a tiny, almost theatrical amount.

But “almost zero” is not zero. It’s like saying “I’m almost not ticklish.” You still flinch a little.

Even the FDA says decaf must have at least 97% of its caffeine removed. That’s not 100%—it’s a loophole big enough for a mouse to squeeze through.

Why Can’t They Just Get It All Out?

Blame the chemistry. Caffeine is a stubborn little compound, clinging to coffee beans like a toddler to a favorite toy. Removing every last molecule would turn your cup into a chemical science experiment.

Processes like Swiss Water or methylene chloride are good, but not perfect. They’re like vacuuming a shag carpet—you get the big stuff, but a few crumbs always hide.

And honestly? If they removed all the caffeine, the flavor would suffer. Coffee needs a hint of bitterness to taste like coffee, not hot leaf juice.
