The first time I had one of these poured for me in the South, I almost screamed when I saw the barman actually turn the bottle upside down to get the last dregs of yeast out of the bottom, and my friends held me back, saying that this was normal procedure in the country and I should not look so worried.
In the days when potentially cloudy beers were sold in England, great care was taken NOT to allow any of the yeast to get into the glass, for fear of severe stomach upset which would require you to spend the following day indoors. For some reason, this beer does not have that effect.
Anyway, having taken a sip from the one photographed above last Sunday, I thought that it didn't taste quite right. Normally, any beer that didn't taste right would also look cloudy like this one, but I really don't know the criteria that is used for telling the difference between a Wiess Beer that is off, and one that is ok.
I asked to borrow some Thai Fish Sauce from a friend once, because I needed to make a curry and the shops were shut. I looked at the date on the bottle, and saw that it was about 3 years older than it's designated shelf life, and mentioned this to my friend.
She said, "Thai Fish Sauce is already rotten when it is first made. It cannot get any worse - there is nowhere left for it to go" so I took it home and used it to good effect.
I drank this beer too - it would have been a case of my word against the barman's. So far, no ill effects.
