Back in November I made a batch of pumpkin wine. I have one three gallon
and a one gallon. I have not at all racked the 3 gallon since racking to
the secondary sometime in February. The one gallon I raked just the other
week. The 3 gallon is still very yellow/orange and doesn't appear that much
has sunk to the bottom. The one gallon a day or so after racking it was
crystal clear. After seeing this I racked another batch that was not
clearing well and it cleared very fast as well. So here is my question, I
actually have two.

1. Why is it that a wine will clear that much faster if you rack it?
2. Since I haven't racked the pumpkin since November, could I get some off
flavors?
