I was looking at the Wyeast seasonal release archive and noticed a couple strains I thought were core strains but they showed up as past seasonal releases.
Past Seasonal Selections | Wyeast Private Culture
Does anyone know if 3522 Belgian Ardennes and 1968 London ESB ale are no longer core strains?
