I've an imperial Russian stout fermenting for about a week now and I took my first sample last night. I sanitized the turkey baster I used, the bucket rim, lid and even used an isolation mask from the hospital I work at. But when I removed the lid some cloudy star san I had in the airlock dripped into the bucket. I heard that once its cloudy it loses its sanitizing properties. Would that be enough to contaminant my stout? I used fresh solution in distilled water when I took the sample but forgot about the airlock..
