So since getting back into brewing and this time getting an MM2Pro as opposed to my previous MM2 I've had a few issues with my efficiency being a couple of points lower than in the past. Used to be 86% now it's average 81% but can swing between 76% and 83% - usually with the swing tending to be in the lower than 81% range. I went from the Robobrew back to using a Rubbermaid tun with bazooka screen like I used to but kept finding I was leaving too much liquid in the tun. Bought the Ss Infussion and used it first time today. Got 83% efficiency but the vorlauf/sparge was a little bit of a pain. I'd read people report that the false bottom lets too many particles through. I found the same. I used a mesh hop bag to strain which worked but it took longer. So, question is if my crush is just too fine. I use a sample credit card that you get in the mail so I assume it's 0.30 but I can't say for certain. Look at the pic and let me know.
