I was at the grocery store and I bought a gallon container of spring water when I got an idea.

Now, I'm new to brewing so this may already be a well known method, but I haven't read about it in these forums thus far. What's to stop me from freezing an entire gallon of water in the container and adding it to the primary? I was planning on taking the gallon of ice out of the container and putting it in the bucket, then pouring the hot (or semi-cooled in ice bath) 3 gallons of wort on top of it. I can then fill the rest of it to equal 5 gallons and see how much the ice drops the temp.

Any objections?

Wouldn't that bring it down too much? I thought you wanted to take your gravity reading at around 70 degrees... my .02

I've actually read about it in other websites. If you do it this way there are two major items to keep in mind.
1. You're diluting the wort with the water so make sure the wort is 'concentrated'.
2. Since you're adding a one gallon ice block, calculate it so your final volume is the desired final volume.

I do a 2 gallon Boil and pour it over a 1 gallon block of ice. That leaves 2 gallons that you can add at what ever temperature you need to bring it to the required temp...Works great

I would make sure to have previously boiled the water for the ice block to be sure you keep it sanitary. Before I started full boils I had problems with off flavors

The gallon jug that I'm going to freeze is distilled water. I don't think I have to boil it.


Any suggestions on how low I should lower my wort temp before I pour it on the ice?

My first batch, i put all 3 gallons of water in the freezer. Man. it went to 65 in no time. I used regular springwater. I'm not sure i'd recomend it. I saw it in a Sam Adams video.

I'm not completely sure on this, but isn't it recommended to use spring water over distilled?

No idea. It's only a gallon of distilled anyway.

I don't know why, distilled is just pretty much pure water.
