Decaf

[EcclesCake]

Is decaf tea and coffee fully decaffeinated or is there a residual amount that remains?

I've been noodling away on the web and can't find an answer which may reflect that it will vary from brand to brand perhaps?

It looks like there`s a small amount left according to this http://www.scientificamerican.com/article/how-is-caffeine-removed-t/

Thanks 237SJ, I suspected as much.
