First go using lager yeast

[Greeny]

Still new to the HB game. Just attempting my first brew using lager yeast. I have just put down a pilsener using Morgans Saaz Pilsener with 600gm LDME and 600gm Dextrose with some extra saaz hops. Yeast used is saflager W34/70 and it was dry pitched @ 22c. Within 2hrs it started bubbling away but the initial bubbling started to die as the temp dropped and this morning it has stopped. Temp of batch down to 14c (Sydney nights getting Cold) which is about where I want to keep it from the temps Sydney is at and from what I have read I will get the best result at.

The question I'm hoping to have answered is is this normal for a dry pitched lager yeast? Start bubbling then stop? Just want to know what I can really expect from the primary fermentation of this batch being my first lager yeast attempt.

Any yeast can become inactive with a large temperature drop like that. 14C is typical lager yeats temperatures but I'm guess the drop from 22C made the yeast go dormant. You really need to stop the temps from swinging so much. It stresses the yeast and makes off flavors. I had a saison that tasted like liquid band aids once.

Try warming it up a bit, slowly and maybe gently rock the fermentor to rouse the yeast

Thanks m00ps. Pretty much said what my mate said when I called him. His comment was I should have kept it at ~22c overnight with a heat belt (14-16 hours) to let the yeast grow and let it drop off over the day time when the temp would have dropped much slower than a night which got to 6c outside. His comment was just to leave it for 3 or 4 days and see if it takes off if not heat it up again as you said. Live and learn I guess.
