Sauvignon Blanc Wine Glasses has another excellent article relevant to drinking SB.  The really relevant bit is this: 

""white wines -- which rarely need to breathe as much as reds -- get glasses with narrower bowls that allow the wine to sit in a more compact shape, helping them keep cold longer."

(Actually I knew that white wine glasses had narrower bowls, but I didn't realize why.)  Most of their taste tests -- I think the results are all in their heads.

The author recommends somewhat pricey Riedel glassware, but amazon carries the Bormioli line, which is much cheaper and receives excellent reviews.

For the article, go here:  The comments are quite entertaining too, with one by me; you'll be able to figure out which one.  So did Salon pay for his $125 test bottles of wine?  Where do I apply?
