Gunns...if you are finding grey matter at the bottom of your glass of tassies it means that the vineyard is distilling grapes with lead piping. This is not actually wine, but rather some thing more like a Colditz brew. There are certain well-known dangers associated with lead poisoning and I have absolutely no idea what they are. Acute impotence could be one of them. I suggest filtering your tassies throuh your socks. Although that might also have health implications. Life is so complicated.
