I'm no chemist, and I only have the basic knowledge I need to make beer. I got into this hobby to create recipes, same reason I love to cook. I started creating my own recipes about 5 batches in, with a few misses along the way I believe I really know now how to build a recipe from scratch and the ingredients I am working with. I say "keep it simple", as big complicated recipes don't usually translate into a complex beer, but simple well calculated recipe formulation always works well.
