I have been playing with a batch of Trebbiano-Riesling, which was very brown when I started it (the kit was at least 3 years old). I decided to go ahead with it and see what happens (not much more to lose). I had followed the kit protocol up to the point of adding Kieselsol, Chitosan, K-meta, K-Sorbate and the "flavor pack." I deviated slightly from that this morning. I had added all the chemicals but not the flavor pack yet. The SG is a very low 0.990, so even though I had not planned on using the flavor pack, I will use some portion of it, maybe all. The color is still way off, so in addition to adding the K and C, I added a dose of Bentonite (2 t. Bentonite in 1/2 C. water). After stirring everything it, here is an updated shot of the wine, still not clear but encouraging:
