I've just taken delivery of a case of 2009 rosso di montalcino and it has a type of sediment I've not seen before. Being a bit eager to try it I didn't really give it any time upright before opening so a slug of sediment came out, almost in a single piece. Thing is it looks quite different to sediment I've seen before, it is a sort of greyish white, almost slimy texture, with a more normal looking dark crystaline sediment embedded in it. Is this normal??
