What do you mean by the deal?

It kills any bacteria that may be in the water and also helps to get rid of Chlorine that is in the water.

When waters temperature gets to 212F (100C) it starts to convert to steam (a gas).

You can boil it for several reasons:

- Precipitate the disolved solids if your water is too hard, so you can later modify it by adding minerals depending on what beer you want to brew (some say this is pointless, but depending on how strictly you want to follow a recipe to brew a Pilsner, which normally has low disolved solids)

- Remove chlorine (like Brewjunky said)

- Kill bacteria (like Brewjunky said)


I don't trust my local municipality to provide consistant, "good" water. They sometimes take it from a local lake rather than the mountains, and it will taste "brackish", it also contains varying amounts of chlorine (more for lake water, less for mountain water). I also live in a 600 year old house, so lord knows what all is growing in the pipes or in the water mains.

So, I boil my water prior to fermenting (I am currently doing extract brewing, so I put cold, disinfected water into the fermenter to dilute the high-gravity extract wort).

Cheers,
Awfers

Boiling only gets rid of Chlorine if your locality uses Gas.. Where I'm at they use chlorine compounds that don't boil out

A carbon filter should clean them out.

If it is a concern, buy a cheap 5 gallon or larger vessel and buy it at walmart. It is like $.35 a gallon for RO. I usually let my tap water sit out overnight and then dilute it with RO. (50/50).
