M&S Silver Frond Sauvignon Blanc is the non-alcoholic counterpart to M&S's full-strength Silver Frond Sauvignon Blanc, drawing on the same Marlborough grape source. The alcohol is removed using spinning cone technology, a thin-film vacuum evaporation process used specifically to preserve the wine's delicate aromatics. M&S describes the result as crisp and zesty, with notes of passionfruit and gooseberry. The Silver Frond sub-range also includes a Merlot expression, extending the series across both white and red.
