Which flavor is essential to all beers?
At the beer festival, Paul talks to a craft brewer at his booth.
Craft brewer: Welcome to our sampling booth! We have a great cucumber spring onion infused summer wheat!
Try our garlic habanero imperial galactic coffee porter! Or would you like to sample our new sour raspberry tart ale?
Paul: Can I just have a beer-flavored beer?
