I normally do batch sparges where I vorlauf and drain off the first runnings, then add sparge water, wait about 10 min and then vorlauf and drain again.
I had a discussion with another brewer the other day where he said that you can just add some boiling water to the mash to raise the temp and then vorlauf and drain the whole batch.
So I tried this technique this morning on a robust porter and my effeciency sucked, 66%. Does anyone else use this type of sparging? Is it normal for efficiency to get so low? The main reason I ask is because my efficiency varies a bit from batch to batch, by about 5%, and I'm just curious if the technique dropped my efficiency or something else went wrong.
