If you use something inexpensive but follow no Rules , then it becomes Expensive
Well said!
Imagine getting the ingredients together for spaghetti sauce. Tomatoes, onions, garlic - hey, cantaloupes are on sale! I'll put one of those in as well.
Everything about brewing is a rule, one way or another - how to mash, how to clean, how to ferment... (here's a tip I learned when studying music theory: if the word "rules" bothers you, it's a little more philosophically satisfying to substitute the word "principles.") All the advice we give, the numbers we spew out, the critiques we offer, they all come from somewhere. Sometimes it's from personal experience, but often we're drawing from the ten-thousand years of brewing history. The likelihood of you brewing a beer that no one has brewed before is very small. While I rarely follow the style guidelines very strictly, I recognize that the styles are what they are because they define beers that people like to drink.
In a recent BYO article, Jamil Zainasheff pointed out that oats don't have a whole lot of flavor on their own. The flavors and aromas we usually associate with oats (think oatmeal cookies) come primarily from the things we mix with them to give them more flavor. Toasting does help, but be careful not to over-toast. Burnt
anything gives beer a harsh astringency. Witbier is often made with wheat, pils some raw oats, and some spices.
I should also point out that even if you mash the oats, your beer may still be a little cloudy, but at least it won't be like gravy.
