Quick quiz: can you name how many different beers you've had in the last week, their country of origin, and their brew style? Do you know what beer to recommend with barbeque shrimp? Have you ever successfully used the word "mouthfeel" in a sentence? Then Beer Citizen is for you. It follows the basic formula for enthusiast "social" apps (in other words, just like BeerAdvocate) but presents all that information in a mobile-friendly format that's got more taste and is less filling.
Friends, reviews, photo annotations - it's all here. The sliders for different qualities is a nice touch for those who want to get really specific.
