It was dark in a hygrometer cylinder. I also noted the extremely dark color in the fermenter but that's to be expected; however I can see it lightening up in the fermenter, and checking in a cylinder again requires me to steal a hygro sample. I'd guess it's lighter than it was.
Northern Brewer kit, The Innkeeper. Doesn't say to add extract late.
There was just enough left in the kettle that the autosiphon wouldn't work with the kettle tipped up about 15 degrees. A lot of it was dark, murky junk. I topped up to 5 gallons, which is the kit size.
The kettle has trouble boiling and requires the lid most of the way on, lifted up at one end, to keep a boil. It burns on 2 burners. Perhaps I didn't mix it enough; I did shut the heat off and stir, but the water was dark to begin with and I can't tell what's in the bottom. There was an LME component, and LME sinks; DME tends to float.
