Porto’s port wine lodges in Gaia are packed with history and barrels, and this half-day walk gets you inside a few of the best ones without feeling rushed. A wine-savvy guide leads the way, showing you cool cellars and an interactive museum where you learn how grapes from the Douro Valley turn into port – from harvest to aging. The real fun is tasting seven different ports along the way, picking up tricks to spot the differences between ruby, tawny, vintage and the rest like someone who actually knows what they’re doing. Everything’s included, so you just show up ready to sip and listen.
