The excitement is real. You've stood in line for a beer, traded from across the country, or are simply enjoying an old favorite. The desire to share with social media circles is powerful and so you pour into your preferred glass take a picture, and post.
Maybe you're at a bar and order a pint of a newly tapped beer. Or at a bottle share where glasses are being passed around at a healthy clip. Being at the source, a brewery, offers a chance to not only try experimental recipes, but established one as well, toasting with friends between flights.
The biggest thing that can ruin these moments is the beer being served in a dirty glass.
