This didn't go quite according to plan! I'd just put the second decoction back in to get to mash out and then life got in the way so the brewing had to be abandoned for the rest of the day. I got up this morning and got started again, the temperature of the mash had only dropped to 50C in about 16 hours so not as bad as I'd expected, the smell was quite sour in a lacto way but I think this might be nice in a wit.

or so I thought! I lifted the bag and somehow I managed to get a "stuck" BIAB

Very odd, the run off was kind of thick/gelatinous (starches?) but I finally collected about 9 litres and got it on the boil whilst doing the first sparge, this gave me another 8 litres of something that looked more like wort at least. I checked the gravities of these two runnings and got 1.104 for the first one (much higher than my normal first runnings) and 1.052 for the second. The second sparge has given me 8 litres at 1.020 so I'm stopping at that. I've tasted the wort and it's odd - a bit like very sweet porridge.
I've just done the maths and my efficiency looks like 96%, that will give me 23 litres at 1.066 - I'm strongly suspecting that not all of my gravity points are coming from fermentables.
Not holding out much hope for this one but I've come this far so I might as well carry on, even though I'm half expecting it to set in the fermenter.
Definitely "F**k Wit"
