I’m not worrying too much about the type of beer per se. The top one was a spec concept based on an existing brewery/beer. Dark color just felt like it worked for the “Muddy” part and hipster graphics 
These days beer types and graphics are so diverse I think it would be kinda hard to communicate the type of beer exclusively by graphic. What does a dry hopped sour pineapple IPA look like?
Really, the exercise is just a fun one to combine some graphics, hand lettering (sometimes), type, logo design, illustration and branding all in one neat package…
