Can someone estimate an FG for this Oktoberfest recipe?

Hi All,

I have an Oktoberfest Ale in primary (boil was on Sunday night). The recipe is below but did not include a target FG. Can anyone estimate it for me? The reason I ask is that I've never used this yeast strain before and the krausen has already fallen about 80% from peak and it was not a very hard fermentation. Since I begain noticing signs of fermentation only on Monday, it seems like I may have a stalled fermentation, although this may be charasteristic of this yeast. Fermentation temp (not ambient) is 68* which is at the high end for this strain, but I think the temp is fine.

Since I don't know the target FG, I can't determine whether its done. Don't worry, I'm not planning on botteling now. I plan to primary for 3 weeks but I am wondering if I shoud repitch.

Assuming a 5 gallon boil and all american specialty grains at 40% efficiency for steeping, you have a 1.054 estimated OG and at 65% to 72% attenuation that you can expect from the whitelabs website it would be 1.015 to 1.019 for estimated final gravity.

Excellent. Appreciate the help! I'll take a gravity reading in another day or two and see where its at.

Just pulled a sample...1.016. You were right on. I can't believe how fast this fermented out with no starter.

Thanks for your help.

No problem. You should let the yeasties clean up after themselves. Leave it in primary for at least another week.
