I purchased 70 new cases of bottles from morewinepro.com and because this is our first bottling I’m not sure if they should be sanitized before use. Again they are new, inside down in their cases on a wrapped pallet. I’m getting conflicting information from a local wine equipment supplier saying don’t bother, and a lot of published info on YouTube and online saying absolutely sanitize. Because of the 840 bottle count and the labor involved with sanitizing them I want to get this right. Would it be ok to hit them with StarSan or should I use Potassium Metabisulfite?
