Harvest time at Yquem. 2013 promises to be a good year not like 2012 which they classified 100%. Grape bunches are coming in botrytised rather than just Berry by Berry. Sweet wine harvest started 26 September and will normally continue for some weeks normally round en October (depending on the weather). The grapes are picked with a potential of alcohol of 20° alcohol. Fermentation stops at 14° when yeasts die off and sulphur is added.
