I have a question with which I hope you can help. I was making an all-grain oatmeal stout recipe yesterday. During the last 15 minutes of my boil, I hooked up my outdoor immersion wort chiller to the hose and tested it out. To my horror, I found a huge hole in one piece of the copper tubing spurting out water. Since I had no other option that I could think of, my buddy went to the store to to get lots of ice. We transferred the hot wort from the cut keg to a fermenting bucket and then put the bucket into an ice bath. Here's the problem -- it took 5 HOURS for the wort to cool to pitching temperature!!! Usually, I can get the wort down to 68 degrees in about 20 minutes with the chiller.
I ordered another immersion chiller last night for the next batch, but I am worried about what this exceptionally long cool-down time will do to my oatmeal stout. Any information or advice would be most appreciated.
Thanks!
