If something could go wrong it seemed like it did. Tuesday I was brewing a Kolsch using BIAB method. 1st time trying a step mash. Step 1 & 2 went off with out a hitch. Step 3 I attempted to get to 159F. With adding boiling water I achieved 151F. Pulled bag & added flame. 9lbs grain & the water it holds is heavy. Achieved 156F, called it good. Got the kettle lid on & towels wrapped to retain heat. Turned my back and crash, the kettle was on the ground. Right side up miraculously, so nothing spilled. One of the legs on my burner failed. Lugged the kettle up stairs to the stove and waited for the mash to finish. Did I mention this stuff is heavy. I knew I would be pressed for time, so I skipped the mashout step. The stove takes a lot longer to bring to a boil, and I wouldn't call it vigorous. With the added time I had only 10 minutes to attempt cooling down with chiller. I got it to 110F, wife was getting after me that we were going to be late. I poured into sanitized bucket, closed, & added an airlock. Three hours later it is only down to 98F. I stupidly shake to aerate the wort thinking it will cool down & I can pitch. Realize that was stupid, closed it up went back to it in the morning.I 11:30 AM it was 69F & I said the heck with waiting longer. Aerated again and pitched US-05. On the bright side I saw signs of fermentation 24 hours after pitching.
