Penfolds 2010 Bin 51 Riesling From Eden Valley, Australia

This is quite possibly the worst wine that we've ever had (it has a screwcap, so there is no possibility that is was corked). From first pour, the wine smelled like rubber and around the table, it's taste was described as "gasoline" or "kerosene." Very disappointing.

Paid $19.95 at Sherry-Lehmann

Remy Pannier 2010 Vouvray From Loire Valley, France

This is a poor wine at any price. At first whiff, the bar for this wine is set low, but the taste is even worse (there's a hint of blue cheese in there). The taste of alcohol stands out as just that – alcohol – and the sweetness of the wine is not what you would expect of the great Chenic Blanc whites that come from the Loire Valley. It’s sweet like a tray of mass produced Italian cookies. Only the aftertaste is somewhat normal. Very disappointing. 

Paid $14.99 at Kings Cellars in Brooklyn

P.S. There are excellent Loire Valley wines at this price point, this is not one of them.
