100% munich alt stuck or just done?

I brewed a 100% gambrinus 10L munich malt alt and fermentation has pretty much ceased at 1.017 (OG 1.050) for the last 3 weeks (66% attenuation). I was really hoping for a dry 1.010. Used WY1007.
Mashed at 150F and below.

I roused it and sprinked in a packed of US05 2 days ago and nothing happened. The bubble looks like it goes through maybe once or twice i day- i never see it happen though. Its 72-80F in the house now.

Could it be that this particular malt comes with a lot dextrins in it? Is this type of thing common for 100% munich brews because the grain is so malty?

Or is pouring the cool wort from 2ft height in to the fermenter really enough aeration? Ive never had a problem before.

any feedback appreciated

100% 10L Munich? I’m pretty sure it’s done. If you would have pitched big and aerated with pure O2 that might of shaved off a couple gravity points. There are some big dopple bock brewers lurking here with lots of munich malt experience, maybe they can give you a better answer.

Did you do a yeast starter? Has the entire fermentation been at 72-80?

I just did a Festbier type of lager that was 100% munich, 25 IBU’s of Hallertauer.
Pitched it onto a whole cake of Wyeast Czech Pils yeast.
It went from 1.056 down to 1.018. 66-67% apparent attenuation, works out to ~5% Abv.
But thats just numbers anyways, most importantly:
It’s pretty darned tasty, and keeps getting better.
I think you’ll like this brew better at 1.018 than 1.010.

Totally. What Scott Miller said.

+1 to ^^^.

I assume if using 100% Munich (drooling right now by the way) that the point would be to have a very malty beer. Which at 1.018 sounds like you got.

What temp did you mash at?

Missed that thanks. Gotta be the Munich then. If it were say pils malt, it would have finished much lower.
