Wes Marshall is the wine writer for the Austin Chronicle where his column turned into the inspiration for a book, “The Wine Roads of Texas,” which in turn has now become a three-part PBS documentary. His never-ending search is for value wines – be they $10 a bottle or $100 – which he defines as tasting better than most other wines at twice the price. As wines become more homogenized, he has been a keen advocate of appellation-specific flavors and aromas, and always marks up for luxurious mouthfeel.
