I recently began my journey with brewing beer, and i bought a 15L bucket with a spigot. After the brew has been fermenting for a week, i decided to make a gravity reading. I forgot to remove the airlock and when the beer began flowing through the spigot, the sanitized water in the airlock went into the beer. If this was StarSan, i wouldn't mind. However this time for sanitizing everything i used potassium metabisulfate. I am now worried my batch is ruined. The sanitzed liquid was created by mixing 10g of potassium metabisulfate with 500ml of water. What do you guys think?
