Paulaner from yeast starter

This weekend I'll be brewing another batch of Paulaner clone. Last time, i put a little of the wort back into the yeast tube and it grew some more yeast. So last weekend, i created a starter, just a couple of cups of water with a cup of DME and that bit of yeast. It's grown a lovely deposit of yeast since then and I'm going to pitch this weekend's batch with that yeast. Let's hope it's good, alive and uncontaminated.
