This brew is in honor of the late Michael Jackson, the ``Beer Hunter'' who passed away last week. This style is one he popularized; this batch is a kit from Northern Brewer.
Some notes: this time I tried doing a two stage mash, holding the temperature at 153F for one hour, then 170F for ten minutes. To do this, I kept the mash in the kettle on the stove. This did not work as well as I hoped. The thermometer, a probe type, fluctuated wildly as the probe moved around, and it took forever to figure out if I had reached a target temperature or not. Time to get a real thermometer I suppose. The final gravity was low, but within the style guidelines, so I think it will be okay. Other than that, the brew went very very well. Each time I do a brew, it seems more streamlined than before.
Here are the notes.
