Alta had a clear vision from day one, to showcase the Adelaide Hills as Australia's premiere cool climate wine region. Emphasis was placed on a careful selection of site, grape variety and controlled yields of the highest quality hand picked fruit. Alta were adamant that the Adelaide Hills would make marvelous Pinot Grigio and have now made sure there's no doubt about it. Alta is fashioned to vibrant cosmopolitan style, relying heavily on the varietal characters and naturally high acid levels in the grapes at harvest to provide aromatics and structure.

The north Italian style of Pinot Grigio winemaking, grapes are picked earlier and do not see any oak, an aromatic wine of profound fruit structure and vibrant zest. Fruit is crushed into fermenters, a complimentary strain of yeast is selected for its ability to highlight primary fruit flavours while enhancing palate structure. A long cool vinification achieves a pristine wine with great depth of flavour. In keeping with the true Pinot Grigio winemaking style, Alta is filtered until the final assemblage, completely unwooded and unoaked.
