Errazuriz Wild Ferment Chardonnay 2000, Casablanca Valley, Chile (Sainsbury's, Oddbins, everywine.co.uk, £9.99). A portion of the Errazuriz La Escultura Estate Chardonnay is fermented with yeasts that occur naturally on grapes. These add complexity and a creamy texture. This price tag is cheap for a wine brimming with scents of roses, apricot and tropical fruit. Sometimes, a tenner a bottle is money well spent.
