I don't expect anyone to spend a lot of time spelling this kind of stuff out so all I'm asking for is a good resource. I'm looking for a resource in which I can study to learn the different aspects of DME, LME, and the different types of grains for steeping. I want to be able to eventually build my own recipes but in order to do that, I feel like I need to know more about the different characteristics of grains and the extracts. Like what colors, flavors, and aromas each imparts on the beer. Anyone know of a good resource for that kind of stuff or is it all experience? (For right now, I'm just focusing on extract brewing, not all grain).
