I have had my brew in the secondary fermentor for about 5 days now. I put it in the fridge because it was recommended to be at around 40F since its a Pilsner brew. My question is does the light hurt my beer when I briefly open my refrigerator door? It's not continuous light but only 3-10 seconds at a time. Am I hurting my beer to exposing it to the light bulb in my refrigerator when I opened the door to get something out???
