Well, evolution has a couple of parts to it. Trial and error gets some results that are good and continue on, and other results that are not so good, and don't live on.
My JTR Irish Red Ale is one of those that will likely go by the wayside. It is actually tasty, but since I'm still dialing in my brewing setup - I ended up with a much 'lighter' beer than I wanted. Lighter as in alcohol content, which is upsetting to me. In past batches, I have sacrificed volume for alcohol content, but this time I wanted to get a full 5 gallons of drinkable beer. Turns out, I think I used too much water and blah blah blah... the beer is bit on the BudLight side of Alcohol content.
Now, this will likely be alright as my family and I will be able to drink all day and not be completely hammered. But damn, I like me some decent percentage alcohol in my beers.
I'll figure it out, though, don't worry about that!
