Champagne growers and houses this week agreed on a 2010 harvest yield of 10,500 kilos per hectare - an increase on last year. This is up by 700 kgs/ha on 2009, following a recovery in sales this year at home and abroad. Ghislain de Montgolfier, president of the Union des Maisons de Champagne (UMC) said, 'We are giving a sign of serenity to illustrate to everyone that the 2009 crisis is truly behind us.'
