40 degrees is quite a bit lower than the bottom range for your yeast. I'd expect that they've gone pretty much inactive. But don't worry! All you need to do to reactivate them is to warm your brew back up to the optimal temperature and provide some gentle agitation. Be careful not to splash! As fermentation has already stated, you don't want to add any ...

No you haven't. But, you should probably let it warm up to the recommended temperature, let it finish fermenting and then switch to fermenting ales for a while. It ought to still ferment fully and be drinkable, but it won't taste anything like what you might expect a lager to taste like. Lagers are really much more difficult to produce well than ales due to ...

Those temps are close enough together that it really doesn't make much difference which you choose. If I had to choose, though, I'd go with the recipe. The temps recommended by yeast manufacturers are very approximate and often too high.

If not ruin it, it will make fairly bad beer. It is always better to wait til the wort reaches a good temp then to pitch the yeast at too high a temp. You can put the fermenter into a bathtub or other container and add cold water and ice to the water. Don't put ice directly into your wort. Ice is not sanitary and you risk contaminating your beer by doing ...

Yes, if that is the target temperature for fermentation is 21-27 C it is most certainly ale yeast. I would just let it ferment an extra week or so at somewhere around 20 C. If you are interesting in true lagers in the future, your shed sounds like a nice place for lagering if you can trust the weather. I think you will find you love the beer no matter ...

I'd try to keep the beer warm for at least two or three weeks to ensure good primary fermentation. If you can do that, I say just go for it. The wild/bacteria portions of the culture will express themselves eventually. Many are slow moving to begin with, and the initial lower temps will not stop them, just slow them down a bit. The beer won't taste right for ...

14C is 57F or so. That awfully cool for an ale yeast. Even 16C is only 60F. That's still below their recommended range. While it may be recommended to ferment at lower temperatures, 4C/8F lower than WL's recommended minimum will definitely slow, and possibly halt, fermentation. You said that initial fermentation was "extremely vigorous" so this drop in ...

I just kicked a keg of Helles fermented with WLP940, great yeast! I pitched at 46°F and let it ramp up to 48°F for primary. I used this quick lager method and the beer was fantastic just 3 weeks later.

No, it won't. Yeast companies generally overestimate the high end temps. They tell you where the yeast will work best, not necessarily the temps that make the best beers. And no matter what the high end is, you'll always get better results by pitching at the low end (or below) of the stated temp range. The first 72 hours are the most critical. If you ...
