Hi I recently made my first 2 gallon batch, I used yeast nutrients and also added in fruit (blueberries & raspberries) my question is more about the yeast process. Im using plastic fermenting buckets, I'm yet to see any activity in the airlock but I've heard that could be down to the gasses leaking out and I shouldn't worry but tonight I got curious and decided to take a quick peak in the bucket I didn't really see any foam but I could hear fizzing like cola fizzes and I could smell what I think is yeast. Is this normal for the mead fermenting process? Also when I looked at the bucket it looked like you could see a top layer of sesame to and also a bottom layer from the yeast dropping down.
