So I've just gotten back into brewing after a 2 year break and am getting horrible efficiencies. I remember getting well into the 80%'s but now am not even getting out of the 60%'s. I've used the same online brew store for all my pre-milled ingredients both before and after the break. I've also kept the same equipment.
I've brewed 2 batches so far since brewing again and after the first I bought a new thermometer as I though the temps may be off, nearly the same result on the second brew day. It has been cold which makes hitting your temps a bit harder but my mash temp seems pretty close.
Here is a picture of the crush through the plastic bag. It seems as if it could be finer but since I've never had a mill I thought I would let you guys decide. I don't really want to mill my own grain but if its either fight with the mid to upper 60%'s or mill my own and get mid 80%'s then I wouldn't care to mill my own. Brewing just isn't as fun if you efficiency sucks lol.
