Wow...I just fed my must with nutrient this morning and aerated when it was at 1.075; checked SG about an hour and a half ago and was down to 1.060. A few minutes ago I started smelling rotten eggs...rhino farts! I can't believe that the yeast ate through the nutrient that fast, but fed it again and gave it one last good stir with the lees paddle. Didn't check the SG this time but will check it in the morning. Smell seems to be dissipating; at this rate my ferment will be about done tomorrow and I just pitched it on the 28th.
