But resisting the urge to panic (too late, I'm panicking!) and interfere, I left it alone and went to bed.
Next morning I could see this was an extreme example of a TILT not acting as expected. Notice the huge jump in SG yesterday (17th) morning? This is obviously the TILT getting caught up in the yeast cap. You can see a small sharp drop in SG after I rocked the fermenter, but after that it's "flat lined" again. As I've said before, a TILT caught up in the yeast mat will remain caught up for a while. My conclusion this morning is the fermentation finished yesterday morning, and the SG will be around 1.018 (it's a historic recipe and "designed" to finish high).
So, this is an extreme example of what a TILT can do, and more reason not to rely on them for final gravities (perhaps if using pathetic yeasts you can get away with it - but I'm British and want to use manly British yeasts ). So the beer is not interfered with and left safe from panic induced introductions of unwanted bugs (I avoid opening fermenters unless absolutely necessary). Hopefully this new TILT PRO I've acquired will be free of such error (when I get around to using it).
Assuming my analysis of the situation is correct?
