Lash night, whilst cooling my fist batch of wort, (5 gallons) something awful happened. I do not have a wort chiller, but there was snow outside. So we put it outside to cool. I later came to check the temperature, (140-150 F), and the snow I had put on top of the lid was of course melted. Because of the vacuum effect, when I lifted the lid it was a little less than graceful, I spilled to water into the wort. Along with a couple leaves... I immediately fished out the leaves with a sanitized spoon, and continued with the process.
Is my beer contaminated? Should I just toss it and make a new wort?
