Mashed a little hot, maybe 158-160. Shouldn't be a problem since most of the fermentables come from the DME anyway.
|

Wow, what a bonehead move. We were cooling the wort to get it ready to go into the fermenter when we noticed that we hadn't added the DME. The last several batches I've done have been all grain, and I just forgot about adding it. We couldn't re-boil for anothe 15 minutes because we'd already done all the hop additions. The DME should be nice and clean, so we just added it to the partially chilled wort. The wort was probably in the 150-170 degree range.
