Time Out says
This honest and unique Barcelona Craft Beer tasting and brewery tour gives you a private experience as you delve into the local craft beer trend. After tasting four fresh craft beers, brewed just ten metres away from your seat, you'll learn how craft beer is made in Barcelona, as the brewer takes you on a guided tour and explains the process step by step. See the ingredients and smell them yourself, even taste them if you want. After the tour you get to enjoy a pint of your choice from any beer on tap.
Along the way to the brewery, you'll get a quick visit to the Born Cultural Center, the Santa Maria del Mar church, Parc Ciutadella and the Arc de Triomf. Photos are welcome. The walk is only about 35 minutes, and you will have time for photos.
