Hi, this is my first lagering, I racked today a pilsner with german lager white lab yeast to a second fermentator. This was fermentating for 7 days at 50 degrees Farenheit and it was at less of a bubble per minute so I racked to a second fermentator. But the smell was unpleasant compared to others I made at room temperature temperature. It was disgusting for me although not for my friends that thought it was alright. Can anyone tell me if its normal? What is that smell? Pleeeease answer me and thanks in advance.
