The Old Vine House in Maribor is home to the oldest grapevine in the world—over 450 years old and still going strong. It's a fun and unique stop for wine lovers, with tastings, virtual reality experiences, and a deep dive into the wine culture of the Štajerska region. If you’re in town in October, check out the Old Vine Festival for great wine and local food next to this incredible piece of living history.
