Our Team

I try to create wines that suit our climate and our way of life – wines to drink with the food we grow, make and eat.

– Spectra

Spectra winery was realised to focus on our passion for the region and its ability to produce dry – grown and environmentally sustainable wine. Recently a new home was established on our holistic philosophy to winemaking which starts with climate, empahasises the importance on the vineyard, as well as wine’s relation to the food we love to grow, cook, and eat.
