German Ale yeast for a Robust Porter?

I have a kolsch bubbling away, well at least I assume it’s bubbling away, havn’t actually looked in a couple days, but my next brew is a robust porter. I was planning on just using US-05 for the porter but then I thought, hey, I’m gonna have a big ol’ yeast cake ready right around the time I am ready to brew the porter.

so who thinks a yeast cake of WLP029 would be a good, or at least interesting, choice for a porter?

who thinks it would be a terrible idea?

Stats

Kolsch OG 1.046
Porter OG ~1.061 (my efficiency had been all over the place lately so I don’t know for sure, might end up a bit higher, maybe a touch lower but right around 1.061)

Do it! Keep it low and it’ll be a nice clean porter

while I didn’t have much luck with it as a house strain, there are a lot of commercial breweries and brewpubs who use wlp029 in everything from kolsch to IPA and porter.

cool! that’s a plan then and I don’t have to make a starter!

would it be complete overkill to just pitch the whole cake? or should I pitch half? can’t relly dump directly on the cake from the kettle as my chiller will only get me down to about 78 so I have to stick it in the fridge to get down that last 20 degrees

Half will be plenty.

Great, I was wondering the same thing as I may be making WY1007 one of my house strains.  Would make a good hybrid Schwarzbier too I think, so I imagine it would make a good porter.
