Mildew is a type of fungus that travels through the air in the form of tiny spores, which land in damp and humid environments in order to colonise and grow. Mildew grows atop flat surfaces, which is unlike the molds that penetrate the surfaces and grow into the materials they lands on.
Due to heavy downpour earlier this month, champagne manufactures are facing losses because of the damages caused by mildew fungus. This fungus infected around 20 to 25 per cent of the champagne vineyards. This adds to the losses caused by frosts earlier in the season.
