Hello folks! Question: After 20+ brews or so of traditional lautering all grain, my buddy and I switched to batch sparging (time saving decision). Since we switched, we always hit the pre-boil gravity (as calculated in Beersmith), but come short (between 5 - 7 points) on post boil gravity measurements (final volume is fine). Can't figure out why since we haven't change our kettle or anything else post mash. Any ideas?
After hearing Denny Conn advocate for using the batch sparge, I've used it ever since. The Brewing Network had him on an old episode of The Sunday Session and after hearing him describe how simple it was, I was sold.
