I am in the midst of my first 15 gallon day with three different 5 gallon batches and I miss-timed something. I have 16 pounds of grain mashing at 153 degrees in my cooler at one hour now, but I still have nearly 40 minutes left on my boiling wort for batch number 2. What can I do with my mash? Should I find some various vessels to drain off the wort from the cooler, or keep it in there and continue the mash for 40+ more minutes?? All help appreciated.
