There are manyvariables as to how fast a wine will clear. Did you add bentonite to it in the beginning as that will help rid the wine of any protein hazes, did you add any pectic enzyme as that will help aid in any pectin hazes. Bentonite will also help aid in dropping out any heavy sediment right in the primary. Temps will also play a big role in this. If clearing naturally cooler temps will help drop sediment, if using a fining agent then warmer temps work better. I cant really tell you how long it will take naturally but if you are in a hurry then Sparkaloid or superKleer is the way to go and I recommend SuperKleer KC as you dont have to do any boiling of water or stuff like that, its very simple and works very fast!
