Default Ice in the wort worked for me... but remember ice expands as it melts to water.

In the past, I have cooked the 2 gallons of wort and put it in my primary without adding the ice, topped everything off with the water and had to immurse the whole shebang in a tub of cold water until I got it down far enough to pitch my yeast. Took a long time. I liked adding the ice, and so far, so good. I racked to my secondary last weekend and it is clearing up just fine.
I just followed a similar process after receiving some advice from the guy at my local home brew store. I made 3.5 gallons of wort. Before putting it in my primary I added some purchased ice to the bucket so the wort would begin cooling instantly (not a lot, maybe up to the 1/2 gallon mark). In my area, bagged ice that you buy at the store must be filtered first, so I wasn't too worried about contamination. Once the ice melted, I mixed it well and checked the OG so that I knew how much more volume I could add. I added a little more ice, let it melt, mixed it well, checked the OG. Repeat. Once I reached the appropriate OG (less than 10 minutes), I checked the temperature and it had already dropped from boiling to about 82 degrees. Almost there in less than 10 minutes! After that, I wanted to continue fast chilling the wort without adding anymore volume that would throw off my OG (volume wise I was just under 5 gal), so I put some ice in a large baggie, sealed it, and put it in the bucket, holding it down and stirring it around for about another 3-5 minutes. By then I was at 78 degrees and was good to go. So I took 3.5 gallons boiling to around 5 gallons at 78 degrees in less than 15 minutes without a chiller. I was thrilled!

My advice would be to not add an entire bag of ice all at once. Remember that ice will change in volume as it melts to water.

That is not true, in fact the exact opposite happens. Water expands once it is frozen. It will contract as it melts to room temperature.
Of note though, you will want to check your volume measurements.

Pipelovejoy,

Thank you for the correction. I got it turned around when typing quickly. I do know that water actually expands as it freezes. That's why you empty some water from a water bottle before freezing it! Either way, my point is to control volume and not let it get away from you by dumping an entire bag of ice in at once.

P.S. I have corrected my previous post.
