I've been making wine from grapes for 3 years, and I'm still not sure if I'm handling the gross lees properly. Here's what I normally do:
I press when fermentation is almost done. The juice goes into carboys. After 2 days I have a heavy layer of gross lees, so I transfer wine off the gross lees.
That seems to work, but last year, when I racked a month later, there was about 1/2 to 3/4" of lees, and I got a rotten egg odor (which went away). This year, I did the same thing, and a couple of days after transferring off the gross lees, I have what appears to be another 1/2 inch of lees.
So, should I be waiting longer to initially transfer off the gross lees? Should I rack what's left (after transferring off the gross lees) in a couple of weeks?
What do you guys do?
Thanks!
