Is there enough yeast in the Crisp lager AG kit from GEB?

[Cptn_Needa]

I'm 7 days in to fermentation of my 9th AG brew and it's the Crisp German Pilsner kit from Get Er Brewed (my first time doing a lager).
OG was 1.043 and it's currently at 1.027 (FV @ 13C).
The kit was supplied with one 11g packet of Lallemand Diamond Lager yeast.
Is this likely to be enough to get it to target of 1.007?

I tasted the sample after taking the SG reading and it was heavy with buttery tastes (diacetyl I think). I'm worried that this won't clear up if the yeast is under pitched.
Any thoughts on this or if I need to take some action?

This is the recipe in case anyone needs more info

Being at 13 it'll take a while to get near FG, I brewed a pilsner yesterday and pitched 2 pkts of s23. I would leave it another week before checking again.
Then I'd look into a diacetyl rest when you are a few points off FG. I don't know much about this as I've never done one but it's to clear those buttery flavours..

I've used Diamond quite a few times and always just one packet and never any issues. I would ferment at 11°/12° normally but as @Clint says give it a week and check back.

Thanks both. Good to know all is not lost at this stage.

@Clint yes I think I’ll give a diacetyl rest a go. The buttery butterscotch flavour was not great.

@Gerryjo good to know you’ve had success on a single packet. When I did the calculator on the Lallemand calculator it came back with 3 packets!

TBH I never use more than one packet of yeast on a 23l brew ale or lager.

Hey, we did alot of testing on these recipes working closely with Crisp Malt & Lallemand and found a single pack was plenty for this brew, lagers/pilsens tend to need a little more time generally so need to panic. Hope that helps Jonathan
