Joinvilense take their suds very seriously and Mad Dwarf is the best of several brewpubs. There's 40 rotating taps, 10 of which are reserved for guest brews (available in pints) while the remaining 30 are devoted to its own concoctions (available up to 300ml). It's just outside of Centro in Atiradores, a quick hop and skip from the bus station.
