What are some ways to add body to beer? I am brewing a stout that is getting fairly good reviews but criticism revolves around a thin body or mouthfeel. How can I affect that? I heard a certain percentage of cara pils maly but was thinking oatmeal as well.
What do I need to keep in mind when trying to add body? Are there any measures/percentages that I can use? How is that controlled by the brewer?
