cold start ferment

[scott78]

hi, im sure im fretting over nothing but i did my first AG lager a week ago. duing the mash i rehydrated 2 packs of youngs lager yeast, my the time i pitched in it was starting to get active. the wort must have been less then 20 when i added it, i know it needs a cold ferment so its been in a cool room (11deg) for a week. i know its a bottom fermenter but i thought i would get some activity on the surface first. should i warm it up to get it started or kep the faith and give it another week?
thanks in advance

I have no real experience with lagers, but at that temp fermentation will be slow and steady.
I think you are just going to have to play the waiting game.

I use S - 23 Yeast for my Lagers , i get activity on the surface after about 12 hours @ 12C

Maybe you should have pitched the yeast at 16 degrees then when fermentation starts drop temp to 12 you should have seen activity by now. You really need accurate temp control when doing lager. Give it a stir up and warm to 16 then if you see signs of fermentation cool down to 12. Usually with the packet yeast you don't need to ferment cool. If you want a decent lager get some good yeast like white labs etc
