Background Information

In vintage 2002: According to Allen Meadows, Ente is gradually changing things “because he is now interested in crafting age worthy and balanced wines. As a consequence, he is doing much less bâtonnage and generally trying to be less invasive in all aspects of both vinification and élevage.”
In vintage 2004: According to Stephen Tanzer, “Ente is experimenting with a bit of lees stirring this year, as this is exactly the style of of wine that can use some enrichment in barrel, but he emphasized that he normally avoids this technique.”
In vintage 2008: According to John Gilman: Ente is now using corks with a wider diameter and coatings with virtually all paraffin in an atttempt to avoid premox. He also uses “virtually no batonnage these days.”
In vintage 2014: According to Steven Tanzer: “ Ente admitted that he had some problems with premature oxidation early on—from 1996 through 2002. But he’s much more confident about the staying power of recent vintages as he’s bottling his wines with considerably lower levels of dissolved oxygen. Ente has also continued to cut back on his use of new oak owing to his experience with Alsace Rieslings, which he loves (fans of Ente's wines will hardly find this surprising). He's also making greater use of larger foudres and stainless steel cuves, not to mention glass containers.”
