I don't know what will appeal to a younger group, since I am a Gramma.. :) I wish to appeal to millenials. My region is now having 1000's of new homes built, and many will be young families moving in. But not just them, I want to appeal to anyone who likes good food, drink, enjoys life. Great value for great wine. Our area is also big for cottagers. 
I like the name of my business. I think it's clever :) Play on words, D-Vine, would be Divine or The Vine, get it? :) My shop will be a fun, friendly place to visit. I'd like the logo to reflect that while still portraying high quality. After all, good wine is the only wine worth drinking, and I take that task very seriously! 
  I do have a store front that will have a sign. I am not sure how to approach this. Will this work for a sign as well, or will I need to design that somewhere else? Will this be my logo for cards, web site, Facebook, etc?
