I too, seek out moderately priced red wines. Thanks for the recommendations. I usually concentrate on Australian and Chilean wines, as Thailand seems to have bilateral trade relations with them. One of the better brands (600 Baht) is Louis Philippe Edwards in the Malbec and Pinot Noir, available in Topp’s Market. And if you can buy and wait a year—some of the less expensive reds at BigC turn out OK—such as LaVida. I even find some decent California reds—Gallo and Robert Mondavi from time to time.
I drink less wine and more beer now because of the cost. And I only drink socially anyway. Happy hunting.
