What beer has 10 percent alcohol?

You may want to consider reWording your question. I'll try to answer this in the two possible angles I imagine you're trying to ask about. Firstly, a beer with more than 7% ABV is considered a High Gravity Beer. Secondly, there are plenty of high gravity beers available in most states. Styles that can usually bear high ABV's include IPA's, imperial stouts, belgian ales, among others. Try looking at the craft beer section for high gravity beers as opposed to your generic domestic section, you'll likely find a larger variety.
