In order to check-in (which is the term used to record a beer on your profile) to Untappd - you need to search for that beer. Once you've searched for the beer you can either use the Quick Check-In feature from the search results, or tap to the Beer Page to check-in. Don't forget that you can also scan a UPC label or QR code on your beer to search for it!
Tap left menu that will bring out the sidebar which contains a search bar.
