So it seems that after 48 hours, my stout has seriously either run out of steam or finished in record time. I'm taking a reading tonight to see if I had the same problem, so I'll post and let you know. The S-04 should arrive today and if I'm high on the FG (which I just have a feeling I am), I'm going to re-pitch, stir gently and see if we can get it down.
bd, I did use the 3711, did a 2 liter starter, and held it at 72-73. That yeast went crazy, highly attenuating, lots of the fruity esters, though I wish I had used more of the orange peel and coriander. My first time with the saison and didn't want to over do it.
