Pre-boiling water for a batch

Post by baldguy80 »

Any of you folks pre-boil (and then cool) water for a batch? If so, how do you store it? Unused carboys?? And is it worth the trouble? (I'm using "city water", as opposed to a well, and I'm wondering if it's a good practice to pre-boil water for use.)

Thanks for the input! (And thanks for your patience too, I feel like I've been hogging the "Beginner Home Brewing" board!)

Presume you mean boiling to remove chlorine?

Should do the trick ok, but I have been using RV type water filters with hose connections for this purpose since I got back into home brewing a couple of years ago and it seems to work fine.

It will remove chlorine, chloramine, and various other elements such as lead etc. You can buy the filters at CTC and probably Walmart in the
RV section. Probably about $25.

I use the filter for about a year for beer making and also with our travel trailer when we go away and replace it yearly. I normally by them in the US where they are a bit less expensive.

Between use, I put the end plugs (provided) and store the filter, wet, in a fridge, which is what they recommend.

Not sure of there is much advantage over boiling, but less trouble - and I only do it when I am ready to fill the boil kettle.

Save the whales ...................................... collect the whole set.

I measure my water out the night before; chlorine will evaporate on its own given 12-18 hours. Chloramine will not be driven of by boiling, unless you boil for extended periods of time (i.e. 20+ hours), so if that's in your water you need to either filter like Brian does or precipitate with a campden tablet.


EDIT: if relying on an overnight evaporation, you want to use a wide-mouthed container (e.g. a bucket). The narrow opening of a carboy will limit the rate of evaporation.

I use tap water for my brews, and have previously used a faucet-mounted filter to remove unwanted chlorine/chloramine from the water. The filter was only about $20 at crappy-tire, and works well. However, because it is designed to filter drinking water right at the tap, it has a rather low flow rate and filling several pitchers at the kitchen sink, then pouring into my kettle just became too tedious. Also, the filter cartridge should be replaced after around 2000 litres.
I now use the same water, but rather than filtering, I simply fill my kettle and add a campden tablet to remove the chlorine/chloramine. Cheap and easy... Just the way I like it.

Like many other brewers, I just use straight tap water, treated with 1/4 campden tablet per 5 gallons. For strike/sparge water, I actually use hot water from my tap. I figure why waste propane and time heating up cold water when there's a huge tank of water already at 130-ish degrees F? Cuts several minutes off my brew day.

I sprinkle in roughly 1/4 of the crushed-up Campden tablet while the pot is filling with hot water from the faucet. I then give it a good stir, put the lid on, and carry it outside to the burner to heat it the rest of the way to strike temperature.
