Im at a loss. I did a test batch using flaked wheat and dextrose, but otherwise following the same recipe except for the ingredient change and the mash stalled after 24 hrs. At 12 hours it was looking very promising, was very active but by the time it crossed 24 hrs, all activity had stopped, the SG readings indicated very little ethanol had been made (<1%). Aroma was good, temp was good, Ph was around 4.2 if I recall correctly. The yeast was fresh, included nutrients and judging from the initial roll, I was expecting a good abv from this test. Since I was changing 2 ingredients (dextrose AND rolled wheat instead of whole berries) I did a second mini mash using sugar along with the rolled wheat. Both stalled. This was my first with flaked wheat, but made sure I heated and maintained at 160 degrees for about 10 minutes, then I removed the grain and transferred the sticky stuff to a small fermenter and added water, just as I always to with this recipe. (I usually pull the starches out with a third of my overall water, then add the other 2/3 to cool it faster so I can pitch and seal it up. This recipe has been spot on many times before, so Im at a loss as to what caused the stall. I may try adding more sugar to see it it will come back...but thats what puzzles me, it should be necessary. Never had to do that before.
