 However at the time of AOC creation, the maximum allowable yields for Saint-Nicolas-de-Bourgueil were slightly lower than for Bourgueil but subsequent revisions of AOC regulations have now made them completely the same for both AOCs.Located on the north "right bank" of the Loire river in the Touraine wine, Saint-Nicolas-de-Bourgueil experiences some of the maritime climate influences from the Atlantic that the neighboring AOCs in Anjou see but with some continental climate elements as well.The Vienne river reaches the Loire at Candes-Saint-Martin across from the AOC creating a large body of water with a resulting lake effect that tempers the climate.
