What is the difference between the KBG and the KBGV Select?

The two are quite similar, as the KBGV Select is built upon the technology of the KBG. The difference is that the KBGV Select has a selector switch which allows you to optimize your brewing for either a half or full carafe. Based on your selection, the water flow and the hot plate temperature adjust so that you brew perfect coffee to industry standards at either amount. In fact, the KBGV Select is the only coffee brewer certified by the ECBC (European Coffee Brewing Center) to brew both a half carafe and full carafe of coffee to their certification standard.
