Anything to watch out for when dumping a new batch on the entire yeast cake? Will it affect the taste much with all that trub on the bottom?
I'd go the yeast rinsing route before I'd rack a new wort onto a yeast cake. There's a lot more than just good yeast in there, and it's generally stuff you don't want in your next beer (dead yeast, hops, break material, etc.). People do it and it'll make beer, but I've been much happier with the results when rinsing. It's a little bit more work, but you don't have to spend a ton of money (a few bucks for some mason jars, or polypropylene bottles).
