The iS10 Winescale and Wine Shows

A Special Licence is available for Wine Shows that enables all judges to utilise the iS10 Winescale for the duration of that Wine Show only, regardless of how many judges are used at the show and whether or not the individual judges are licensed to use one of the iS Winescales. Go to Wine Show Licence.


Any publishing of iS Winescale scores by the Wine Show will be permissible. Publishing of iS Winescale scores by judges individually after the Wine Show will require an individual licence for that judge.
