Giesen 0% Sauvignon Blanc is part of the brand's alcohol-free wine series, made from grapes sourced across New Zealand's Marlborough and Waipara regions. Giesen uses spinning cone technology to dealcoholise the wine, a process that captures the aromas before alcohol removal and reintroduces them at the end, preserving varietal character through the dealcoholisation step. The regional sourcing from Marlborough and Waipara is shared with other wines in the brand's 0% range.
