so yesterday i messed around and gave the crock pot vs UC a full test. I must say really impressed with the result. I have a recipe I know inside and out. I dont even know how much of this mix Ive made but its alot. I used to use the ultra sonic all the time. 15 mins on 15 mins off for a total of 4 hrs then let it rest for 24 hrs. Ill add real quick that I have also had alot just naturally steep because i make so much of it. when i used the ultra sonic there was always more of a TH with it even after a 24 hr rest than a natural steep but not enough to swear off the UC . now fast forward to yesterday. i made my mix and had already had my CP at 150 degrees for at least an hr making sure i could keep a constant temp. dropped the bottles in and went about my day. 2 hrs later. opened it up, it had a pressurized burp , capped it shook it kinda and back in the water. 2 hrs later took it out again. opened it up, no pressure built up this time shook it up and in the cabinet it went. this morning threw a fresh wick in and filled my tank up. the TH I experience with the UC is gone and there is this smoothness and creaminess Ive not tasted before. sooooooo good. from what i can tell the crock pot is hate to say it better in my opinion. the creaminess im tasting is awesome. lets let my noob shine through a bit and even say I think it might even be better than a natural steep. like I said I know this recipe like i know walking around my house in the dark. there is no need for 6 bottles of various testing this against that etc. maybe the UC shakes it to much or something. Ive messed with heating over the past few weeks but first time Ive tried it on this recipe just because like I said Ive got some much hanging around Ive never really needed to speed steep it anymore. so anyways wanted to throw in my 2 cents into the crockpot vs UC vs natural steep and my results. CP-1 UC -0 lol.... its so much faster. 24 hrs and its ready and very very tasty.
edit. also tested the temp of the liquid in the bottle. at 150 degress water temp in the crock pot at 2 hrs the liquid inside the glass was only 139 degrees.. at the 4 hr mark water temp was 150 liquid in glass bottle was again 139 degrees. made 20 ml. not sure if the temp would go up or down with more or less liquid inside.... something to test next I guess.
