Provides Winemakers with More Choices for Their Wine Programs  MODESTO, Calif.  (January 19, 2023) – Diam Bouchage, the leading manufacturer of technical cork closures for still wines, sparkling wines and spirits, has introduced new permeability options for its popular DIAM 10 and DIAM 30 corks designed to provide winemakers with more choices for their wine programs.   The new closures can be viewed at the Unified Wine & Grape Symposium in Sacramento, January 25-26, at the Diam booth, #538.  “Oxygen management is critical for winemaking, so Diam offers a wide range of products with different oxygen ingress rates (OIR) and oxygen transfer rates (OTR) for our Diam 2, 3, 5 and Origine by Diam corks.  However, winemakers have been asking for a cork option with higher OTRs and this solution will provide them with a brand-new tool to consistently age wines after bottling,” said Dimitri Tixador, director of permeability at the Diam Bouchage&
