Now I am going to be trying to make apple cider, but I am asking this question for learning purposes first. I wanted to use tap water and let it ferment with other ingredients plus the champagne yeast I have.

1. I was wondering is tap water safe to use, if not do I have to boil it first? or can i just filter it?
 
you should boil the water. The nasties that can ruin your ferment can pass through a filter but not a ten min boil.

thank you very much, I appreciate your help a lot. I bought a filtering system and I thought that would be good enough, I guess that was a waste though. Ill boil it as you mentioned. I'm not a big fan of beer so I hope this cider works out. Thanks again.

edit; btw would bottle water be ok to use without boiling?
 
If you are doing cider why would you need tapwater to begin with?

I am only asking this question for learning purposes. I will be making cider with apples, but I also heard of people making cider with frozen juice concentrate that has no preservatives, so Im assuming they add water to that if im not mistaken.
 
Many brewers, including myself, use tap water for top-off without boiling. It depends on the quality if your tap water. For beer, the only thing I do is add campden to take care of chlorine, but as I understand it, that's not necessary for cider or wine.
 
On the rare instance where I have added water to cider I have used bottled water because I didn't want to bother with campden tablets for dealing with chlorine/chloramine

What if I were to add tap water to the actual batch and not just for top-off?
Would I need to boil it first or can I used bottled water instead without boiling?

Thank you for your help
 
That's what she said. I routinely use tap water for various parts of my brewing operation. Starters, top off water, dissolving priming sugar. I have faith in my city water supply.
yeah thanks i edited my message, after I noticed that.... and thanks for the help.
