I have been around a while..brewed a bunch of what I consider good beers...some not so good. I am doing all grain...wash and save yeast..have a 3 tier gravity system...have good temp control ( well semi good) what is the next step to improving my brewing? I REALLY like this hobby but feel like I am just replicating what everyone else is doing...meaning I basically brew other peoples ideas and recipes. What should I delve into next that will educate me more on brewing my own beers?
