I'm trying to start a Google+ Brand Page for a specific liquor. We are required to restrict any page we create to users that are 21 years of age or older. I noticed that I had the option to select either "Users 21 and over" or "Alcohol related" under the "It's content is appropriate for" section. However, when I try to select either the "21 and over" or "Alcohol related" options, the page states that "Our product is not available for you yet. Please come back later."

Any idea why that is? Is that option simply not available yet, or are there other steps I need to take first (for example, verifying that I do in fact represent a liquor company)?
