Cold Brew experiment results.
@mikewilburn ooo I forgot about this. Edited in the results.
tl;dr the colder the better starting water temp imo
I had a plan for ratio's but the brewer ended up not having the room for it all. I'll set up a new batch over the weekend

The purpose of this test variation is to find a methodology that will support the best balance of strength/taste but also allows me to start at the end of a work day and drink at beginning of following work day. I have carried over the 5/1 ratio and 21 grind size measurement from previous tests. I am hoping by starting at a hotter temp, as was done in test #4 but leaving the conditions from the highly rated test #2, I can achieve the desired balance. Volume measurements done using side of mason jar.
This test is the result of a failed test from yesterday (undocumented) that used less exact measurements and very cold water.
Update: Edited quality after taste test. Smooth, did not need to be cut flavor wise. I found it to be too strong though and needed to be diluted. This is what contributed to me not giving it an A. Also, took a long time to filter but that may just be how it goes.
