The 2006 Bordeaux vintage is progressing well, the Conseil Interprofessionnel du vin de Bordeaux (CIVB) has said.

Climatic conditions of good sun, high temperatures and moderate rainfall since April, have been very favourable to grape maturation, after a particularly rainy March, the CIVB said.

"The sanitary conditions are good," said Michel Gayllard, oenologue and production director for Andre Lurton's seven Bordeaux vineyards.

Ludwig Vanneron, oenologue with Michel Rolland's laboratory in Pomerol said grapes had a tendency to be bigger this year and, where possible, had benefited from a second green harvest, or pruning.

The grapes have started to mature, and if the same favourable conditions persist, harvests could start at the end of August for whites and mid-September for reds, the CIVB predicted.
