Default Is store bought bottled water sanitary?

I'm going to brew my 2nd batch soon and was thinking about various methods of cooling the wort. My plan is to freeze bottled water from the store (will the plastic be able to stretch when the ice expands?) and put them into the primary. I did the math and found that 3 gal of boiling hot wort and 2 gal of Ice come to about 80 F which should be ideal for pitching the yeast.

I read a previous thread about using Ice to cool the wort and found that even store bought bagged ice may be contaminated. That's why I want to freeze it in the botle. I didn't want to bother boiling the water before I freeze it since this might be a waste of energy if it is not necessary.

Thanks,

You should be fine. This is exactly what I have been doing for years (I use distilled water to be safe.)

As for the expansion problem... you could rupture one of the bottles in the freezer. It happened to me with a 1 gallon jug one time. Ever since then, I started dumping out a half cup of water from each jug, re-capping, and then putting them into the freezer to give the water room to grow as it freezes.

One more thing... on my last two batches I used 3 gallons of ice-cold (but not frozen) water to chill my wort instead of 2 gallons of ice. I did this because I got sick-and-tired of having to cut the plastic bottle off the huge ice blocks I was pulling out of the freezer.

This also solves the ruptured water bottle problem, but you DO have to keep an eye on the water to make sure it doesn't freeze when you aren't paying attention.

The melting of Ice actually absorbs most of the energy from the hot water. That's why I plan to use ice so I can still boil 3-4gal of wort. I'll see, how much cutting the jugs open will bother me.

But thanks for the tip with dumping some of the water.

When you did your calculations, how cold did you assume your ice was? That's going to play into this. One time my 2 gallons of ice OVER-cooled my wort and I had to add boiling water to bring it back to pitching temps.

I'm sure you'll be fine. Best of luck!

I thought using distilled water was a no-no because it has no minerals and stuff. Is that not the case?

Just add yeast food if you are doing all extract and use distilled water. Otherwise the grains will provide everything the yeast need.

I used two 2L soda bottles in my last batch. (I keep them in the big freezer for trips to the store, I'm way up in the hills!) Sanitized the outside & put them in the pot. Could have hooked up the chiller, but I was being lazy.

I should have been more specific... I use 3 gallons of bottled spring or drinking water in my kettle. I only use the distilled water for the cooling since I won't be boiling it.

Question: if the grains provide everything the yeast need, then why are things different when using extract? After all, that extract was made from grain.

I checked the web site for the spring water that I plan to be using, and they say that they disinfect the water. I assume that this is a requirement for all bottled water and I don't have to boil it or use distilled water.
