On the way to a boil now, gravity isn't great. 1020 temp 54, temp adjusted to 1031. I can only think the bag i'm using isn't letting enough liquid to mix with the grains, i was expecting to be close to around the 1040 mark. As the grains filtered through, the wort was lovely and clear, i got bored of waiting, so started putting through another colander without a bag, more cloudy, but a lot quicker. Did i do the right thing?!
I've reviewed feedback in this and other forums, and went with the followng method\recipe:
2.5KG Marris otter
100g torrefied wheat
160g Crystal
6L water to 73.7
Grain into pot
stir out lumps
check temp, build slowly to maintain 68, insulate and leave for 1 hour, stirring after 30 mins. Added extra 1.5L of hot and cold to get 67.6. temp dropped after stir, so added heat back up to 68.3-68.4. ended at 68 degrees
strain through bag in colander into FV
Heat 10L water to 78
add grain bag and steep for 10, then stir and strain into large pan
I'll then boil up, add hops etc.
