Yeah, I'm clearing the W.E. Luna Rossa right now and I don't know if I'm ever going to see a light through it. Shining a light on the side I can see a line of demarcation that is moving about 3" per day down the carboy, and plenty of pink sediment, but I can't see a flashlight beam from the other side at all, even at the top. I guess big reds might not allow much light through? Or will it eventually get clear enough to see a beam through?
