There might be something to this yeast washing thing

On my way out the door this morning I saw the beginnings of fermentation in the 090801 Geordie Boy Ale, which (I suppose) demonstrates the efficacy of the yeast I reused from the 090702 batch. I'm traveling, but I got a report from the brewmistress that there was a foamy krausen layer on top of the brew tonight. I guess I'll wash this cake as well. Need to get some more quart jars and a gallon jug.
