(Decanter) - Napa winemakers are hoping for a 'Bordeaux-like' vintage, as the harvest gets into its stride with rain and its hazards a constant presence. Some 3.8cm has fallen between 3 and 6 October, with all the attendant problems of rot, mildew and dilution. While some are playing down the worry – it ‘shouldn’t be a major setback,’ Chris Phelps, winemaker at Swanson Vineyards said, ‘It will cause delay rather than be a declaration of disaster’ – all winemakers are aware of the danger of rain at harvest time.
