In the spiritual homeland of Malbec, many of the most innovative new wines being produced today are white. One might be forgiven for thinking that winemakers are being deliberately contrary; however, over the past decade and a half, underneath wave after wave of reds, a revolution has been simmering away quietly. Chardonnays and Sémillons are now being produced that are every bit as good as some of the best Malbecs in the country.
