My first two brews where 5 gallon kits which included 6.6# LME and about 1# specialty grains each. Since then, I decided to experiment a bit and try my own recipes or tweaking others. All of my recipes are a base of 6# DME and about 1-1.5# specialty malts. So the issue I have is that the two brewers best kits I made had fuller body and nice head retention. My own recipes turn out pretty thin and have almost no head. Is there something that I'm doing wrong? Also, with the kits, I did not sterilize the included priming sugar. I simply poured into the bottling bucket and stirred. Since I purchased a 3# bag of sugar I sterilize it then pour into bucket. My carbonation doesn't seem the same as when I simply poured it into the bucket.
