Notes

Just brewed this today (7/6/14) at the request of my wife who just had a baby and can now enjoy a beer or two a bit more freely. We hit all the gravity, temperature, volume, etc targets that I wanted. The wort smelled and tasted great, seems like it is going to turn out really good. I will update in a few weeks once I get a taste.

The brew turned out good. It was judged as 32 points out of 50 in a local home brew contest. I think a mediocre fermentation was the culprit. I will brew this again, especially since I have now improved my fermentations by dialing in my fermentation chamber and adding an oxygenation system to my brew gear.

Based on contest comments I will: improve fermentation, beware of oxidizing the grain, mash, or wort, increase the % of oats, and edit the dark grains to achieve more roastiness.
