I have two of the Cellar Craft/Vineco KenRidge showcase reds on order from George. I have the standard 7.9 gallon primary fermentors, and am wondering if I need a larger primary for these kits since they have the 2.6L "super pack". Just want to know if I have to get a bigger primary for these to avoid making a mess. If I do need a larger primary, what would you suggest? Thanks
