So I have been brewing for almost two years, mostly extract, and I just started doing some all grain kits. I've been noticing that my all grain beers have little to no head. And they have also been taking longer to carb. My extract kits all had good head and carbed fast. I'm thinking I am doing something wrong during the brewing. I brewed a coffee stout and a Indian brown ale, both have terrible head retention. Both are taking their sweet time to carb. I did a partial mash pale ale using the same equipment and no problems with head, but it had some LME in it...
