    I brewed a stout last Wednesday and by Thursday evening the air lock was popping at a good pace. That night a heavy winter storm hit and early Friday morning I lost power. The fermentation slowed and came to a standstill. Power is back on as of 7am this morning. What do I need to do to save this beer? Any help is appreciated.

    So the lack of power means a loss of heat as being your issue? I don't think there will be any problem with the beer finishing up. The yeast likely went dormant but should revive and finish their work. I'd try to slowly get the temp up to around 70-72 for a brief period to 'goose' those little buggers a bit and wake them up, then back to 65-70 for the finishing process.

    Nothing. As long as your wort temperature gets back to where it was, the yeast will finish the job. And no need to 'goose' above that range. (And I can think of at least two reasons not to.)

    Normally yeast will come back to work when temperature falls in the correct range, if it doesn´t(wait 6-8 hours) then give the fermentor a gentle shake to rouse yeast.

    How far off the temperature did it get? Did you measure the gravity? It could just be done with the visibly active part of fermentation?

    As long as your worth never freezes you are good. Total freezing will break the yeast membrane cell and kill it.

    Rookie error.

    I've had several lagers partially freeze when fermenting in our attached greenhouse in the winter. They all resumed fermenting when they warmed up and were fine. No need to do anything special.
