Hi, took the leap and had a go at making my first ever batch of turbo cider today. I added 2 ltrs of apple juice to a sterilised DJ, sprinkled in about 150g of sugar and added a pack of yeast (didn't realise until it was in that it was wine yeast, not sure if this is good or not). I then topped up with another 2 1/2 ltr of apple juice. I loosely place a bung in the top with an airlock. Within minutes the inside of the DJ looked more like a snowglobe with all sorts of stuff floating about and the airlock was bubbling away merrily. Is this normal or am I worrying too much?
