I started a mango passion fruit wine a couple days ago and usually ferment in a bucket and the move to a carboy. This is a smaller 3-gallon batch and it ended up in a Fermonster for a variety of reasons. When I went to check on it last night, I was mesmerized by what I usually don’t get to see under the cap as fermentation is in full swing. Apologies about the sound, it’s fairly quiet until the boiler kicks on.
