Topping off a fermenter

When topping off your fermenter to 5gal should the water be boiled first?

Some do, some don't. I never did and never had any issues. I'm not suggesting I'm right, I just never did it.

No boiling for me, but I use bottled water to avoid adding chlorine.

Most of the time I don't.  I don't recall ever having a problem either.

I don't either.  I top off with bottled water.

I use bottled water if I need to topoff. I think sealed bottled water is sanitary enough not to cause a concern. I don't like to use a bottle I've already opened, but honestly that's probably fine as well.

I've topped off straight from the tap numerous times with no issues.  However, I'm lucky to have very good water.  YMMV....

I top off with filtered tap water.  I do not boil, water runs through a carbon filter deal under the sink.

Are you not able to do full boils?  If not, +1 on topping off with bottled water.  However, before I was able to do full boils I just topped off with filtered water.  No boiling done.

Now that I can do full boils, I don't add water on purpose to a fermenter.  Before I add my immersion cooler to the boil, I will check the volume and top off if necessary.

I used to use tap water, before doing full boils.  If you use a proper starter and your water is satisfactory then you could probably get away with topping the fermenter without boiling.

i often have a few quarts of wort left over from mash, as my efficiency seems to be a touch higher than my program calculates. i top off with that when needing extra volume, and i do boil it just to be sure.

with wort that is a very good idea. there are a lot of microbes on that grain and not all of them are going to die at mash temps.

Just remember, if you are adding water boiled or not you airate well. Boiling removes oxygen, you need to put it back.
