THE GENERAL ASSEMBLY,

IN VIEW OF Article 2, paragraph iv of the Agreement of 3 April 2001 establishing the International Organisation of Vine and Wine,

CONSIDERING the work of the “Microbiology” Expert Group,

CONSIDERING the monograph COEI-1-NOSACC Non-Saccharomyces selected yeasts,

CONSIDERING the latest studies done on products and subproducts of non-Saccharomyces yeasts,

AT THE PROPOSAL OF the Commission Oenology

DECIDES to modify the resolution OIV-OENO 674-2022  and consequently the monograph COEI-1-MANPRO adding to part 1. "Object, Origin and Field of Application" the text in bold and removing the strikethrough text as follows:

  • Mannoproteins are extracted from Saccharomyces cerevisiae  spp. or non-Saccharomyces yeast cell walls by physico-chemical or  enzymatic methods.

DECIDES to modify the resolution OIV-OENO 452-2012 and consequently the monograph COEI-1-EPLEV adding to part 1. "Object, Origin and Scope of Application" the text in bold as follows:

  • The proteins of yeast protein extracts mainly come from the cytoplasm of Saccharomyces spp. or non-Saccharomyces yeasts.

DECIDES to modify the resolution OIV-OENO 459-2013 and consequently the monograph COEI-1-INAYEA adding to part 1. "Object, Origin and Scope of Application" the text in bold as follows:

DECIDES to modify the resolution OIV-OENO 496-2013 and consequently the monograph COEI-1-AUTLYS adding to part 1. "Object, Origin and Scope of Application" the text in bold as follows:

  • Yeast autolysates are derived from Saccharomyces spp. or non-Saccharomyces yeast biomass.

DECIDES to modify the resolution OIV-OENO 497-2013 and consequently the monograph COEI-1-YEHULL adding to part 1. "Object, Origin and Field of Application" the text in bold as follows:

  • The cellular yeast hulls are obtained from Saccharomyces spp. or non-Saccharomyces yeasts.
