Here is what I did:
-Started the kit on 2/16
-Racked on 2/23 with SG of 0.998
-Racked on 3/5 with SG of 0.990
-On 3/5 added metabisulphate, sorbate and stirred for 2 mins
-On 3/5 added 1/2 the f-pac and stirred for 2 mins
-On 3/5 added isinglass and stirred 2 mins. Topped off with reserved wine.
-The four week kit was scheduled to be done on 3/15 - I mention this not because I think all kits are done in four weeks, or should be, just for reference
-From 3/5 to 3/21 it sat in my kitchen under airlock
-It was clear with the color of apple juice by Friday 3/21 and looked beautiful
-I picked up the carboy from the floor and set it up on the counter on Saturday 3/22 at 11AM, planning to rack and then bottle, but the wine in the carboy became cloudy when I moved it. It seemed like the sediment was stirred up. I let it sit on the counter for a day, but the sediment did not settle out, and it acutally got cloudy all over without me stirring it or doing anything else.
-Added Superkleer KC on Sunday 3/23 at 4PM, which states it will clarify in 24-48 hours. The package stated to put in the first package, then wait an hour for the second package, which I did. Stirred gently per the instructions.
-It is 3/25 Tuesday afternoon and it is not clear AT ALL. Looks completely cloudy like primary fermentation.
I haven't had this issue before, so it is strange. The wierd thing was that it cleared until I picked it up, and then hasn't been clear since. I am really diligent about doing all the racking, stirring, sanitizing because I don't want to ruin a $200 kit (not Mezza Luna but others) by being a lazy stirrer.
