On the Wine Trail is local in the sense that blog-master, Alfonso Cevola, lives in Dallas and mentions local themes and places once in a while. But Cevola is also something of an international authority. A lifelong wine seller whose mom's mom came from Calabria at the toe of the Italian boot, just across from Sicily, Cevola can tell you all about things like the tension within the Calabrian wine world over strictly regional tastes versus a more international mix of grapes. If you were real lucky, you could get this kind of stuff from him in person any Saturday morning when he might happen to drop into Jimmy's Market in East Dallas for some wine schmoozing. But the blog is the more reliable place. A salesman for Glazer's Wholesale Distribution in Dallas, Cevola has watched Dallas' wine palate develop over 30 years. Asked what the big new thing is in these times, he said, "Wine under $15." He's got the skinny.
