So I did an all grain stout today and my og came in super low. Was supposed to be 1.080 but instead came in at 1.052, and that's after temp adjustment. Expected og was calculated by the beersmith app, and unless I got screwed by the local brew store, all grains called for in the recipe were accounted for. Here's what I did for the 5gal brew:
Heated 4.5 gal mash water to 178, poured in 10 gallon Cooler mash tun, added grains, stirred until I hit 154 degrees, closed lid and let it sit for 1 hour. Vorlaufed 4 times, drained wort into kettle. Added 4.5 gal batch sparge water at 170 and stirred again till 154. Let sit 15 minutes, vorlaufed 4 more times, and drained into kettle.
Now I did end up with about 1 gallon too much wort and I didn't want to waste it, so I boiled what would fit into my kettle and then added the extra gallon once I'd boiled off enough to fit it in. That didn't take long, maybe 15 or 20 minutes. Any ideas what went wrong with my og?
