I have made about 10 batches of hard cider. I have yet to have a contamination issue ruining a batch. I clean the carboy with washing up liquid and warm water. The bottles are the same. I use a juice if juicing apples, and that's not sanitised.
I read a lot about the need to be very careful with sanitization for beer homebrewing, which I'm experimenting with now.
Is beer more vulernerable to contamination than homebrewed hard cide for some reason?
