I know there are different versions of each, like Light or Dark, I II III. I'd like to have the general differences between the two, mainly!
The "cara" in CaraMunich indicates that it's a crystal malt. It's essentially "mashed" in the husk, then kilned to produce sugar and a glassy kernel, like other crystal malts. Munich malt does not go through that process. It's a relatively dark kilned malt than can be used as a base malt. Their flavors and uses are very different. Munich can be combined with other base malts or used as 100% of your grist if you like. CaraMunich, on the other hand, has a much sweeter flavor and should always be used as a "character" malt in relatively small quantities (generally less that 10%) of your total grist.
