No, Affenberger does not operate a public tasting room. It's a production-only or by-allocation label, so its wines are found through retail, restaurants, or a mailing list rather than an on-site visit.
Affenberger is in Prebensdorf, in the Vulkanland Steiermark wine region. Phone: +43 3113 2984. Confirm hours before visiting. Winery schedules vary seasonally.
