I've been on a kick lately where I've been wanting to experiment with using yeasts in a manner they traditionally aren't intended for. My first recipe called for pitching an imperial stout onto a yeast cake of Ringwood, no tasting yet though.
For my next idea, I'd like to rack a heavy milk stout onto a cake of WLP500 Trappist Ale yeast. The question though is, what lighter gravity beer should I pitch the vial of 500 into so that I can have a nice cake to rack onto when it's done? I was thinking maybe an ESB, or even an Irish Red, but I'm open to suggestions!
