Brewing again tomorrow, but this time with some darned wyeast yeast nutrient. Pitching collected yeast slurry combined with an aerated starter I added yeast nutrient to.
I think I would hold above 5.5c until fg is reached.
In my experience lager yeast stall below 42f.
I'm certainly in no position to disagree, but that seems to be in contradiction to what other people here seem to be experiencing ? The paper regarding LODO Helles brewing suggests holding at 3C until FG, and someone here mentioned holding at 4.5C as a safer bet. I don't mean to come across as ungrateful for the feedback. It's all good, and I appreciate every bit of it. Just confused by conflicting information.
I have held a batch a primary temp (8C) after transferring on an earlier batch, and it stalled all the same, so I suspect temp isn't the issue. I'm hoping adding yeast nutrient at the end of the boil, will finally get me over the line, if all other things are in order.
I'm not saying everyone else is wrong either, just my experience. The brewers from devil's backbone had come to the same conclusion as well.
I'm sure yeast strains has something to do with it as well.
