Sidewood Estate is a substantial family-owned Adelaide Hills producer, owned by Owen and Cassandra Inglis, farming vineyards around Oakbank and Nairne in the cool, elevated Onkaparinga Valley. Its higher-altitude sites sit on sandy clay-loam over ironstone and schist, where cool nights and a long season give bright, aromatic white fruit with fresh acidity. 'Nearly Naked' is the estate's zero-alcohol sparkling, built from a house blend of estate and Adelaide Hills white grapes selected for delicacy and natural acidity, made to a consistent non-vintage style rather than one season.

A dry white base wine is made conventionally from cool-fermented Adelaide Hills white varieties, then de-alcoholised to zero per cent, most likely by spinning-cone or vacuum distillation to protect aromatics while stripping the alcohol. The de-alcoholised wine is balanced and carbonated to give a crisp, dry sparkle. Because the alcohol, and much of the body it carries, is removed, the focus falls on preserving citrus and orchard-fruit aromatics and keeping sugar in check. Exact base varieties, de-alcoholisation technology and finishing NEEDS VERIFICATION.
