Hi all
I was brewing my house pale ale this morning and I got a very high OG 1.061
I step mashed from 123f for 30 mins then rose temp (using berms) to 152.5f for 30 mins then mash out at 170f 10 mins, sparged with 20.5 L at 173.5.
I was 2.5 Litres short in the kettle due to human error 😜
Grist
2.5 kg Maris otter
2.5 kg Vienna
.075 acid malt
Ph was 5.35
My usual efficiency was 75%, according to these figures I got 104% efficiency 😂
hydrometer is calibrate in water seems correct (re checked) refractometer reads the same...unless I added too much grain...possible but..... I'm at a loss
If I added 1kg too much my efficiency would be 87% surely not (taking into account lower boil volume)
Any ideas or suggestions as to what might have happened
