Z WINE is seriously dedicated to making some of Barossa Valley’s best wine. Z is for ZERK, a pioneering Barossa settler family in 1846. Janelle and Kristen Zerk are fifth generation Barossans and are the only sister duo in the Barossa Valley who produce, own and operate their business. Their wines can proudly stand alongside many well-known wines. The Cellar Door and dog friendly wine bar is in the main street of Tanunda and is popular with locals and tourists alike, offering regional produce and local live music to accompany the selection of distinct wines. They have a shaded verandah that is dog friendly and overlooks the main street.
