Will be bottling my first batch tomorrow... Finally drank enough crafts to have enough bottles. I made the solution that cam in the kit during making the brew and stored it sealed. My guy at my lhms told that that is fine and would last no problem. I was just going to rinse my bottles in the solution prior to bolting tomorrow in six bottle batches. A friend of mine told me I should pre-sanitize my bottles by soaking them overnight in a chlorox solution.... Is this really necessary?
