This is more of a general question that I'd like to throw out to homebrewers that like to 'experiment' with beer recipes. I've been through enough all-grain brews now that know my equipment fairly well, and even though I'm still learning tips and tricks along the way I want to throw out a question on experimenting with different ingredients (different yeast, malts, hops).
I like the art and science of brewing as much as drinking my results. So much so that I really enjoy seeing how certain combinations taste rather than just attempting to make a 'clone'.
Do any other curious brewers that like to try to make their own recipes have any suggestions on ways to experiment various combinations most efficiently?
