Wanted to brew some cider and purchased a Munton's Autumn Gold kit. Has been brewing now for 8 days and was just about to put it in the keg. However, I have noticed that there seems to be white spots growing on the surface. Is this and infection or just yeast? There are no colours, just white spots. All was sterilised correctly and has been fermenting with a lid on. Spots must have appeared within the last 3 days. I have posted link to an image below. Thanks!
