I found this on a different forum...
"We're low on Crushendo due to a processing issue. We have lots of raw materials, but the grapeskins are processed in a very specific, very finicky way. Our previous processor (who did a great job) didn't really want to do it from the start, and was doing it mainly as a favour to us. We switched to another processor, but they had trouble with the fractionation sequence and retort processing."
