Wine maverick Josh Wesson of Best Cellars says, "fear not the screw top!" There are good bottles to be had sans a cork. Here's some to try:

From France: Colombelle Gascon Blanc. About $8

From the United States: Bonny Doon Vineyard Big House Red or White. About $12

From Australia: Jacob's Creek Riesling. About $14

From New Zealand: Felton Road Premier Pinot Noir. If you can find it, get it! About $90.
