Hello everyone. I just brewed my 100th batch of beer today and for all of those I have used Beersmith. The last few batches I am now all of a sudden a half gallon short (5 gal into the fermenter instead of 5.5). What is the best way to fix this. Start doing 6 gal batches? I have changed my mash efficiency to 78% from 72% Will this effect anything? My volume into the kettle is spot on, so do I increase my rate of evaporation? I have a pretty good grasp on all numbers but need a little guidance. Thanks.
