So, i brewed a batch of oktoberfest recently. It was my first lager and my second beer with a yeast starter. I realized that the marzen yeast i used was faulty, and after a few days of no fermentation, i decided to pitch two packets of dry lager yeast from my local hbs. anyway, that took care of it and it fermented, but had some off flavors. A weird sweetness, i would say. And it the aroma is just like strawberry preserves. Anyone ever have this, or know what its caused by?
