I have a big RIS that started at 1.100 and is now stuck at 1.034. It's on WLP001, from a stir-plate starter (~400 billion cells). I suspect aeration caused the stall as I use the 'shake' method to aerate.
It started out vigorously, but is now without question stuck (2 weeks unchanged). Most everything I can find says to rack it onto a new yeast cake and the combination of a little bit of oxygen and the new cake will get it going again.
My next planned batch is a citra hopped XPA, somewhere in the 60 IBU range. I'm pretty sure this RIS could hide anything at this point. The RIS is already 90+ IBU from magnum/goldings.
Are any off flavors from the yeast cake from a citra hopped beer going to show up in the RIS?
Any dangers in reusing the yeast cake? (autolysis, trub, over-pitched to restart, ....)
