I started a new batch of wine 4 days ago. I used the recipe I found on here using 5.5 gallons of pure wleches white grape juice, I followed the recipe and its got a strong smell to it right now. Its in a plastic fermenting right now with bung and its not horrible but its enough that when I come home and walk in the door I can really smell it , like someone cooked eggs for breakfast or something. I am wondering if there is a problem here ? My other batches used only a couple gallons of pure juice with water is the only difference I can say here. I have heard about the rotten egg smell with wine making. I can not say its horrible rotten egg smell but kinda like your cooking eggs. Wanted to get opinions on this?
