This is a great way to refine brewing processes. A very light beer where defects are more easily noted is the best way to really enhance one's technique. For example, altering grind settings to see the impact on lautering, yield, flavor, and fermentbility. Change fermentation temp by a couple degrees and see that impact. Continue to make other small adjustments to see what the impacts are. Then, apply the learnings where applicable. Happy Brewing.
