Yeah it is all grain, with coriander, orange peels and rosemary. Definitely a lot trub. I did notice some trub under the hyrdo so I swirled it around. This is the best explanation so far.
Yeah it was still floating. Jus kind if strange. I even pulled a sample out of the fermenter after fermentation had stated and it was at 1.030.
Evaporation could have occurred, my main concern is that iam getting proper extraction.
Yesterday I brewed a hefe (great recipe I might say) and with a hydrometer reading I got 1.044 at 70 degrees. I left the sample out overnight and now it only reads. 1.033 . How does the sample differentiate that much with no variables taking place?
Since I started brewing All-Grain I have had some batches will lower efficiency and I think this may be related to me using a batch size of 5 gallons instead of 5.5 gallons(what is actually going in the fermenter) . I know efficiency is related to the amount of sugar in an amount of water.
If...
The temps are high because you will lose anywhere from 5-10 degrees from just transferring it to mash tun and then by the time it hits the grain bed it will be around 168-170. Hope this helps.
