Some think this stresses or kills off yeast. I've washed yeasts from 7.5% lagers, did a starter, and had no issues whatsoever. Drinking a Doppelbock right now that was re-pitched with a Dunkel Doppelbock yeast. It is clean and delicious.
Never tried it with a 10% Quad, not sure I'd risk such a costly beer for an experiment.
