I bought a 52 qt igloo marine cooler and have been using the SS braided line. I have had some terrible numbers lately, so I took some more accurate temp readings tonight. Tonight is a big beer - Bombastic 1.075. Because my efficiency is so low, the LHBS set my efficiency to 65% in proMash.
Almost 20 Lbs of grain, mashed in with about 6 gallons of water at about 164 degrees. I was using a digital thermo that was inside the mash tun. Started great. 153, then 152 about 5 minutes in. Then it started falling quicker. Needless to say, last time I checked I was at 144 with about 12 minutes left in my 60 minute mash.
Should the temp drop this much? I thought it held very constant after you mashed in. Thoughts? What am I forgetting?
