De Bortoli Fizzero Sparkling White is the white expression in De Bortoli's Fizzero range, which also includes a Sparkling Rosé. The Fizzero line takes a different approach from the brand's The Very Cautious One dealcoholised wines: it uses 100% bacterial fermentation of grape juice, with a green tea infusion, rather than yeast fermentation. The brand states this process generates wine-like complexity without producing alcohol as a byproduct.
