What does the "bold" setting on my Cuisinart coffee maker do? I recently bought a Cuisinart coffee maker.

It has a button to switch between "regular" and "bold" when brewing.  I have no idea what this actually does.  I thought that usually bold coffee came from different beans or from the amount you used, not from a setting on the coffee maker.

What does this function do and when would I use it?
"Bold" appears to be a flavor term in general, usually referring to a type of bean; however, on coffee makers, it appears that the water drips more slowly, which allows more flavor to be extracted from the beans. This source confirms that this appears to be the case on at least one Cuisinart model.
