My wort chiller will not be here till tomorrow. So my brother the chef said about useing ice direct in the wort. I explained not to use unless you know it is not infected and such. So what we did was. Use ice from our ice maker. It is the same as the water that goes into the wort. So the theory is that it will be fine. The beer we used it on is popping away and smells good comin from the airlock. So the hopes is that it will be ok. Also the ice got added while the wort was still at about 200 degrees. So assuming there was something in the ice, it died. We did not and will not add ice from the store. Just our home ice. Think it is ok? we will find out in a cpl of weeks.... Ha!
