Time Out says
The Barcelona Beer Festival is back! This is a great chance to get to try craft beers from all around the country and beyond. You'll find a huge bar with more than 80 taps, where they rotate the more than 350 participating brews that are all great examples of national artisan beers, plus this year for the first time, some quality international names as well.
The festival works with its own glass and currency that you can get at the selling points around the venue in L'Hospitalet. Beers will be poured only in the official festival glass and only the festival currency will be allowed as payment. The entrance fee includes the glass, a guide and your first two tastes. It also gets you access to a variety of parallel activities on, like tastings, presentations, conferences, and talks with the aim of spreading the word and educating on craft beer culture.
