Just about to bottle a stout, it's been in my 2nd FV for a couple of days and the temp has dropped to about 15 degrees, when I bottle it and prime it, will it start to ferment again or have I ruined it by letting it get too cold? Also, what kind of temperature do you keep the bottles at?

It will be fine, there will be plenty of yeast about although they may be a little sleepy due to the temp. I would bottle and bring them back to the warmth for 2 weeks for the yeasts to convert the priming sugars, back cool for a week and then drink... enjoy

18-20 ideally...any lower than that and it probably won't carbonate, at least not in a couple of weeks. Any lower than 16 and it won't go at all. Have you got a hot water tank cupboard? If not, I'm stuck for an answer...

There's your answer then - unless there's a risk of 40 bottles becoming 30... :)

Just a word on low temperature fermenting. I used to put my beer (all grain) in 25litre plastic cubes that used to hold sherry, they were free from my local club. Clearly they could not be pressurised or they would explode. BUT.. in the winter I used to prime and put a cube in my garage for a couple of months in freezing conditions. ALL of the gas stayed in the liquid at low temperatures and the conditioning was superb. Which shows that yeast does work if given time at low temperatures. And this was with ale yeast not lager yeast.
