Hi guys,
I have recently brewed to big beer: One double IPA and one wheatwine.
I usually achieve a 80% mash efficiency. I don’t know why but for these 2 beers my mash efficiency dropped to 60%.
I have changed nothing to my process :
- I mill my grains with a double roller monster mill. My gap is set at 0.61 mm which is fairly narrow.
- I have a tree vessels system with one kettle and two coolers.
- I continuously sparge over a long period of time like 45 minutes.
- I don’t experience stuck sparge.
I’m wondering if its my mash tun (Igloo cooler) that have difficulty to handle too much grain.
Any clue why my mash efficiency get so low?
