So I took a couple years off from home brewing and just started up again. After I brewed an extract kit I put it in an ice bath to cool down to 100°. I then put it in my fermentation bucket and added about 3 gallons of water that I had in Individual gallons in the refrigerator. Unfortunately, I have been using one of the gallons to store my star san mixture in. As soon as I started pouring it into the wort I could see that it was somewhat cloudy and I stopped pouring immediately. My question is, have I ruined the whole batch of beer?
