Homebrewers - Whats in the fermenter?

[BeerAdvocate]

Last night I racked a basic Blonde on a Hefe yeast cake.
I have never reused a yeast cake before, hopefully it will turn out good.
This morning it was bubbling away.

Okay, hang on, I'm trying to understand what you did--did you just rack a new batch of wort onto the leftover yeast & trub sitting in the bottom of a fermenter? And it worked? That's genius!

I've been brewing for a lot of years, and I've salvaged/washed a lot of yeast--in fact, I have about 6 bottles of re-used California ale yeast sitting in my fridge, waiting to be pitched into something. But I've never just started a new batch off of a completely spent yeast cake. Sure would save me a lot of effort!
