Hello, first time poster. Somewhat new to AG brewing (and brewing in general). I made an Imperial stout OG 1.084 FG 1.018, so it was about what I was looking for. The recipe called to add champagne yeast in the secondary, so that's what I did. I was wondering if I should rack the beer again if a yeast cake forms at the bottom similar to what I did in primary. I plan to have this beer in secondary for a while (~6 months or longer) and I figured racking it separated it from the "trub" at the bottom to reduce off flavors. I'd appreciate some opinion in this matter. If you need any more clarification I'd be happy to provide some.
