Captain Morgan has put drink recipes on their website to promote the use of their rum as more than just something you add to coke. It seems to me they are trying to appeal to a younger audience that wants to try new drinks and share with friends. Captain Morgan’s most recent ad campaign has been trying to promote itself as the choice of alcohol for a night of fun with friends and using owned media like their web page to share recipes for people to try out with their rum is a good way to further that idea.
